Well the dream begins. I'm embarking on the building of a 914 project. Here is the candidate. Bought a roller from LA area. Looks like its not going to be too much rust. Firsts thing will be to strip it. Taking front fenders and rear quarters off. Then sending to Cal Blast for media blasting. I look forward to the knowledge that I can gain from fellow enthusiasts. Plan on taking a lot of pics Stay tuned......

Come to the G&R swap meet. Lots of stuff there you will absolutely need. Forget the roll cage. (Unsafe in a street car). Go with the Sheridan body. first.gif

Just out of curiosity, why would a cage be unsafe in a street car?

and Elliot, wasn't there a Cage in Zonker? Personally I felt a lot safer with a Cage in my car. It was padded

Generally cages are unsafe in street cars because you don't wear a helmet on the street. Since the 914 is so small, it's likely in an accident you will bump your head on the roll cage. In that event, the cage always wins.

I see your point. Thank you for the heads up (pun intended) However, since I am making this a speedster, I'm thinking of moving the rear hoop to be more in line with the back of the firewall.

I'm going with Sheridan. I changed my mind (September 17, 206). I'm going with 916 steel gt flares and will offset the front and rear fenders 2 1/2" and then add the 916 gt steel flares. I need to offset the front and rear since the 996 suspension has a 5" wider track. Trouble is the rears are set up for 14" rims. I don't know if there is rubber to fit that wide? When is G&R swap meet. I would definitely go. If it is in Riverside, then it's only a 45 min. drive up the 15.

I have most of the car stripped. Making a rotisserie. As soon as rotisserie is completed I plan on media blasting. Looked into media blasting with pressure washer and crushed glass. Looks like that is the way I will be going. I'll post pictures as soon as I complete the rotisserie.

The Zonker had a roll cage but I didn't install it. I bought the car as it was. I don't like a roll cage for the street because it just doesn't "give" on impact. Roll cages and roll bars are there to protect you from a roll-over. Every time a chassis or body is bent and crinkled in an accident it absorbs energy and increases the chance of survival in a collision. That's my .02 worth. (although some consider it to be worth about .015). lol-2.gif

I can personally recommend the Sheridan body. They are made here in Paso Robles, are well made and are incredibly strong. I'll be at the G&R and can tell you from my experience how strong they are. biggrin.gif

Well here are some more pictures of the progress. We have removed everything inch of wire, grommet, tubing, cable. All we need now is the suspension. Building rotiserrie before i take suspension off. My trusty helper is my son. We are enjoying this project immensely. Attached Image

Take good care of that Harness! Your gonna need it when you restore it welcome.png

Posted by: Curbandgutter Apr 16 2013, 02:22 PM

Thank you for the suggestion. Also with respect to the harness, I'm going to have to do a diet on it as I won't be using any of the engine fuel controls. I'm also going to need some grommets as I found it impossible to remove the harness through the rear firewall without removing the large rubber elbow. Also there were some relays underneath the passenger seats that were completely rusted out. I could not remove them without cutting them out. I will be needing a factory manual to see exactly what those relays are for.

Posted by: Curbandgutter Apr 16 2013, 02:38 PM

I'm also planning on removing the center tunnel and making my own. This can serve various purposes: it makes it easier to re install the wiring harness, the fuel lines, the drive by wire throttle, the hydraulic clutch line, and it gives me the opportunity to install the shifter at the proper height. Also, I have been toying with the idea of bringing a cold air inlet from the front of the car to the rear via this center tunnel. Obviously the cold air/ram tunnel would be separate from the other cables. I could remove the existing fuel tank and buy a cell that fits into the spare tire well. It would be a direct ram of cold air into the cold air box! piratenanner.gif Also the center tunnel would be taller and much stiffer than the low profile one that it came with. This would add additional stiffness to the frame. The Sheridan front certainly has some real estate in the front for various ports to accomplish this. What do you guys think?

keep it up! a lot of work ahead, but it will be worth it!

Posted by: Curbandgutter Aug 4 2014, 01:13 PM

Well it has been a while but I have been collecting "stuff" so that I can start and not have to stop too often. I purchased a 2000 996 C4 that was involved in a fire. I am able to use the full suspension, Brembo big reds, jic coil overs, radiators, ac condensors, power steering, power brakes, transmission, axles, pedal assembly. I am purchasing steel flares this week and then I will be able to start work. I will be posting pictures of the German piece of coal donor.

It is going to be a 916 like you haven't seen yet. Top is coming off, steel speedster humps, lowered floor, lowered glass and raked back. Steel cage/frame. I'm wanting to modify the 996 aftermarket front bumper to work with the 914 front an 916 front flares. I'm also removing the front square pop up lights. The real surprise is what I have planned for the rear fender and quarter panel. More to come.

Posted by: Justinp71 Aug 4 2014, 01:31 PM

Sounds like a good project... funny, one just sold on ebay (not flared though). If you look you can see the radiator behind the seat even, that's new on a v8 car.

Whats your plan on using the transaxle in mid engine conversion. I don't think you can rotate the 996 transaxle to run in a inverted posistion. Is the ring gear reverseable like in the 930 boxes. idea.gif

You can invert the 996 gearbox. Verified with GBOX. Only thing is that I think that I will need to add taller ring and pinion. If I use a 325/30 19 tire with stock rear it will cruise 70 MPH at 2550 rpm. If I use the 3:1 rear end, then it will cruise 70 MPH at 2200 rpm. I'm getting a quote to do the taller rear and LSD. Let's see what it ends up at.

Posted by: Curbandgutter Jun 7 2016, 07:15 PM

It's been a while......life happens. I'm back on track and started to build the rotisserie. I'll finish this weekend and then I'm going to media blast. Enjoy the pics.

Well here is the rotisserie that I made. I took the best ideas from all of the different ones and made my own. I am satisfied with the way the rotisserie came out. I'm now waiting for my wet sandblasting kit from Power Eagle. They are on back order and will be available at end of June. For now I will just pick up the recycled glass and wait.

Well since I have to wait until my sand blast kit shows up, I'm taking the front and rear suspension off the 996 to mock up on the 914. Looks like the front will be easy. The rear will require a tube frame. That's OK though since I am planning to tube the rear. I'm planning to pressure wash the suspension this weekend and mock it up on the rotisserie with the car upside down. cheer.gif

Neat project.

For mounting the suspension, what are you using for a datum or reference plane to make sure the a-arms are not tilted too far forward or back? Any part of the suspension that is supposed to be parallel with the floor pan?

I've really thought it through and finally came to the conclusion that a modified 916 look is what I will do. I will extend the 916 flares enough to cover the 245/18 front tires and 335/18 rear tires. I have thought it through though as I want to stuff the wide tires but I don't want a ridiculous bulge at each corner. I have a couple of tricks up my sleeve to accomplish this though. Also the 996 suspension will make this car to have a 5" wider track in the front and a 4.8" wider track in the rear. It's interesting that the wheelbase of the 914 is 4" longer than the 911?? dry.gif

I will be building a chassis table. Also I have the 996 on hand to compare the measurements. I will be putting all of the measurements into software that will tell me what the instantaneous roll center (IRC) of the 996 is. Then I can make sure that I am not lowering the IRC. If anything I might set the suspension cradle of the 996 further up into the 914 chassis to lower my CG. When I place the 914 on the chassis table I will carry out a twist test to see what the torsional stiffness of the 914 is before I add the 8 point roll cage. I have structural software to design the roll cage as well.

whats the smallest wheel that you need to clear the brakes? I would aim for that size. 18s are way too big for a 914. 17 would probably look good with that wide body and still fit over the brakes

Is it your opinion that it is too big because of your preference or that the wheel is too big and won't fit. If it's just your preference I can respect that. However if you're saying that the wheel is too big then ponder on this. The original 914 wheel rolling diameter for a 914 is 25.4" the 335/30-18 rolling diameter is 25.9"??? Also as they say a picture is worth a thousand words see the attached picture which shows a stock 914 wheel next to a 265/35-18. As you can see that tire is shorter (it is under inflated), however it's rolling diameter calcs out at 25.3 in. Am I missing something?

Is it your opinion that it is too big because of your preference or that the wheel is too big and won't fit. If it's just your preference I can respect that. However if you're saying that the wheel is too big then ponder on this. The original 914 wheel rolling diameter for a 914 is 25.4" the 335/30-18 rolling diameter is 25.9"??? Also as they say a picture is worth a thousand words see the attached picture which shows a stock 914 wheel next to a 265/35-18. As you can see that tire is shorter (it is under inflated), however it's rolling diameter calcs out at 25.3 in. Am I missing something?



Thats a preference thing for sure.


I run 18's rear and think it looks great. I personally prefer 17's in the front though as to have a little better ride quality.

Don't forget that the floor diaphragm is there to take the shears. The cross bracing is at the transmission - rear suspension area. I will be providing tube clamps to be able to remove the struts when needed. Good eye though.

Sweet! You don't see too many people doing FEA iterations on chassis. smilie_pokal.gif

What software package is that? Almost looks like Ansys APDL or maybe more like Grape? You're modeling with beam elements or trusses? Can you glue a shell element floor on to better match reality? In one of the racecars I worked on laminating a thin carbon shear panel on the floors increased stiffness by 25-30% (experimentally verified via twist test too).

I think you're seeing artificially high loads in N43A because of the huge open box in the cockpit. If you add triangulation near the doors and closer the floor I bet you'll move some of that load path (if my visual FEA makes any sense haha).

Your loading seems a little weird. Why load the lower arms so highly in the vertical direction? They shouldn't see all that much vertical force since it's really all desisted by the spring/damper unit. Why not model the suspension in as an infinitely stiff member and then load with bump, lateral, and longitudinal forces? Then you wouldn't have to draw a free body diagram to figure out point loads.

With actual loading N36B might be more heavily loaded than you think (and in some combined weird bending/buckling mode so it probably needs a big safety factor). If you're doing frame stiffness twisting it (via moment about the front suspension nodes with the back fixed) seems more widely accepted than loading one side. There is a good SAE paper on it, I might be able to find it somewhere.

Sorry if you know all that stuff already. I'm not a mechanics guy by any means but I've spent a bunch of time doing chassis design/analysis for some tube frame racecars and a Lotus.

Now that's what I'm talking about! aktion035.gif aktion035.gif aktion035.gif Love this kind of input. Now to answer some of your questions. The lower A arms were not loaded, what you are seeing is the 3 points where the suspension cradle is bolted to the chassis. The 900 lb vertical load represents a 5g load on the wheel. The next step will be to simultaneously load a 900 lb load in a downward fashion on the opposing suspension cradle support points to create a couple, or rather twisting of the frame as you mentioned. I will be running the same scenario at the rear and then run another scenario to simulate bending forces in the frame. I will go ahead and model the floor and both firewalls with plate elements and see what happens. Might as well model the "longs" as well. this will give a better representation of the behavior.

I'm modeling with beam elements with fixed joints in all directions being that the joints will be notched and welded.

I would love to get my hands on that SAE paper. I'm sure that I will learn a couple of things.

Hey thanks I'll remember that when I need it. Right now, I'm getting a feel fro the way the frame will behave. The next item on the list is to build the frame table and to mount the 996 to get all of the suspension pick up points tabulated. Then mount the 914 to start building the chassis with the same suspension pick up points built in. I'll be using a plumb bop and a laser meter to measure and square every thing. It's finally coming together. piratenanner.gif piratenanner.gif

Hoping it is built with I beams and 1/2" plate, so you can weld to it. In reality the I beams are fine, you should make the plate float on individual sections. So you can level the plate separate of the frame.

So it looks kinda like this on a much larger scale.

I am making it out of 4x4 tubing. The tubing has much tighter mill tolerances than hot rolled I-beams. Also square tubing is much better than an I-beam in torsion. To make it out of an I-beam I would have to have it blanchard ground. I'm going with 4x4x3/16 frame with six 4x4x3/16 legs. All cross braced with 4 casters and 6 leveling screws. I'll tack weld on the ground enough so that I can raise and assemble. Then I will level all six legs with my survey equipment. Once leveled I will continue welding all seams a little at a time and from opposing corners so that the table does not warp. Then I will finish in that same Hunter Green as the rotisserie. That small chassis table looks like it's awesome for small projects though.

beerchug.gif I get worried that people will take offense to comments like those sometimes.

Gotcha, I just looked at your pictures again; didn't realize the 996 stuff was all on a subframe. Now it all makes sense.

Looking at that model again it might get stiffer if you switch from the bent front windshield frame halo-style bar rearward facing bars like found in a non-halo cage. Then you'd spread the longitudinal bars (N44 and N43 maybe) out towards the edges moving them further from your head and building a better node at the windshield corners. I just get scared seeing cross-bracing put hoops in bending. It might also be worth switching around some of the triangulation (ie: in front of and behind the door) to meeting at the same places to form some "super nodes." I noticed on the full tube chassis that this seemed to help stiffness without any weight penalty. The x-bracing on top and bottom of the rear might make maintenance very difficult. I did this over a chain drive differential in the name of stiffness and really hated myself for it after the fact. You could probably get most of the stiffness with a bolted shear panel. Hopefully that makes some sense; I can draw it tomorrow really quickly too.

The 5g load is pretty conservative; I've always designed around 3g bump, 2g lateral, and 2g longitudinal loading (though not all at the same time since tire friction circles limit the combined grip) and haven't had many problems. Your analysis plan sounds good to me! Unfortunately I'm at a conference right now and having trouble remoting into my regular computer to look but I'll check for the paper as soon as I get home.

Totally unrelated to the design stuff, but when you notch everything be sure to drill small holes in all of the receiving tubes at the joints. Being able to back purge while welding makes the whole process much better. You have less problems with oils, etc. running out and end up with much higher quality welds. smile.gif

2g Lateral in front yields a WHOPPING 0.70" lateral defelction. This is the worst case. It makes sense too in that the hole where the engine is allows this deflection. I'll have to fix that somehow.

Nice! Those numbers look great! beerchug.gif

If you have time it might be interesting to run a case with a bunch of tubes connecting the rough engine mount locations into one node. At least it'd give you some idea of how much deflection the engine stops (assuming it's not super softly mounted). I bet with an "engine" surrogate in there you'd get a lot of the 0.70" back without making any other changes. Adding a bolt-on stressed panel under the engine (could double as a belly pan for aero) would bring back a bunch of stiffness too.

Two pure curiosity questions...How much does it weigh? What software are you using for FEA?

Posted by: Curbandgutter Jun 24 2016, 11:52 AM

That did it. Since the lower frame is flush with the bottom pan of the car. I can bolt on a plate along the bottom and it totally fixed the flex. The flex now is 0.1" as opposed to 0.7"! I like the way you think. beerchug.gif beerchug.gif The bottom plate will also blend into a rear diffuser. I am planning on exiting my exhaust above the rear bumper line.

With regard to weight it will add about 150 lbs. However, the front and rear hood, and the front and rear bumpers will be fiberglass. I'm going with about 600 HP av-943.gif so the extra weight will not be a distraction.

beerchug.gif

Fantastic! Easy fix! My guess is that you will retain nearly all of the added rigidity even if you have to cut some holes in it for access to things like oil filters, etc.

The weight doesn't seem bad at all, especially considering that you are cutting out existing structure and using some glass parts.

Is this design using different diameter/wall thickness tubing?

Posted by: Curbandgutter Jun 27 2016, 04:51 PM

It uses thick tubing for the main hoops and thinner everywhere I can.

That's a lot of metal there. But then again your connected in the welding biz, right?

Posted by: Curbandgutter Jun 27 2016, 06:35 PM

No more connections. We used to be in the industry 30 years ago. Now the only connection you need is the green kind. Damn steel is crazy expensive. hissyfit.gif hissyfit.gif hissyfit.gif The material was around $1,200 barf.gif I'm usually in the office, so if you're by the area come on by.

Looks like a NASCAR chassis, which would be a good reference.

Hard to see numbers with my eyes, but you will need bars at n14-n15 and in the front n13-n06 and n12-n07, or your first t-bone will be your last anything.

Posted by: Curbandgutter Jun 27 2016, 09:41 PM

I see what you mean but just think how much better this car will be than stock. Or even those that only are able to reinforce the longs. I think I'll be all right.

Posted by: Andyrew Jun 28 2016, 08:15 AM

So your not planning on gutting the chassis and putting this tube frame under it? Because that what it sounded like.

Posted by: Curbandgutter Jun 28 2016, 01:34 PM

No I'm not gutting the entire chassis but I am removing quite a bit from the rear. It will not have the rear strut towers, transmission mounts, engine support, rear suspension attachment points, rear lower trunk sheet metal and engine sheet metal wrap around.

Posted by: Curbandgutter Jul 9 2016, 08:14 AM

Well I've had to take a break to prepare for my son's wedding. I've taken little windows of time and worked on the chassis table thoug. It's almost complete just need to add the webs for the trusses and it's ready to mount the 996 on it first. I'm going to compile xyz coordinates for all of the suspension pick up points on the 996 and then transfer those coordinates onto the 914. That way I will keep the same suspension geometry that the factory had. I'll also be doing a twist test on the 996 and on the 914 pre-tube chassis and post tube-chassis. It will be interesting to note how much better the 914 chassis will be. I'll be taking all of the measurements with a laser plummet and a laser distance measure....stay tuned.

Sweet table! Very very nice! drooley.gif You work fast!

I've always wanted twist measurements; they should be really interesting. I've built solid "shocks" and twisted some formula cars. It's relatively easy to do and really neat to see how the results compare to FEA expectations. Unfortunately, our FEA was always a bit optimistic because it didn't include finite stiffnesses for all of the suspension joints.

It would be really interesting if you could twist it a few times after the tube frame with and without the engine, belly pan, etc. just to see how much incremental stiffness each piece adds.

Posted by: csdilligaf Jul 11 2016, 10:30 AM

Looks like your moving along well. I did a 914 with 993 suspension a long time ago with an LS6 and G50-52. I had the rotisserie and set up and a welding table For the suspension set up. With no room to store the stuff I got rid of it and now I have a new 914 project starting and was planning on making all the stuff again. As you know it is a huge investment and a lot of work. How about right after you get your chassis set up and of the table you do mine and recover some of the money you have in all this effort? I am just down the road in San Diego. Also here is another thread that you may have seen but its always good to see what others have going and see how they went about things.

CSDIILIGAF hey that 914 you did with the 993 suspension looks killer. Let's talk about using my rotisserie and frame table. I'm thinking that I can just rent it out to you for an extended period of time. That way your cost will be a fraction of the cost to make and I get a little back for my investment. PM me and give me your contact information I'm sure I can learn from someone who's done it already. Glad to have you commenting.

Posted by: Curbandgutter Jul 11 2016, 12:43 PM

JD74914 Instead of using the solid shock idea, which is a cool idea by the way, I was thinking of just setting the car up on 3 jack stands on the frame table, clamping them down and loading the wheel that doesn't have the jack stand under it. What do you think? Is there a better way? And yes I would like to test the twist under various conditions. We're just going to geek out and have fun with the numbers as well as the final product. biggrin.gif

Posted by: Curbandgutter Jul 12 2016, 10:17 AM

Does anyone have a good idea as to how to set up a jackstand with some form of a clamp to attach to bottom of longs? Taking all good suggestions. Bad ones screwy.gif will be ridiculed lol-2.gif lol-2.gif . Just kidding of course but yeah let me know how you'v e done it or saw someone else do it. BTW no Mo-Clamps those are North of $200 each.

Posted by: Curbandgutter Jul 12 2016, 11:32 AM

I'm thinking of welding these to the end of a 2x2 post and using them instead of a jack stand. They are cheap and will do the job.

Weld a block of steel on one side, and tap for 2 3/8" bolts, add another on the others side and pinch the seem. Add knurling if you want between the jaws. Stands will need to be able to move as this design is not self centering.

Attached Image

Our weld C clamps to the to of the jack stands.

Or weld a set of nuts to steel plates, weld steel plates under the rockers, bolt them to the fixture and grind them off once done.

Put wooden blocks under the rockers, drill holes through the rockers , wooden blocks, and fixture, use all thread, bolt it down.

I am guessing this is to do twist testing.

I would weld three legs down, and not use jack stands, as you will have to strap the car down anyways

Use weldable trailer rings onto the logs, put what ever you want under it, ratchet it down with welded rings on your fixture.

Trailer rings can be found that are rated for 18,000 of force per ring, and cost about 12.50 per ring plus shipping. Then some big straps, or chain. Or just load binders.

Cast, thinking they will break at the bolt hole as you apply force diagonally to them.

Posted by: Curbandgutter Jul 12 2016, 12:23 PM

914FORME I like your idea about the trailer rings. Yes that will be necessary to be able to hold the car down for the twist test. I'm going to hold down into concrete with a wedge anchor. I do believe that the clamps that I have are rated for 750lbs. I'm going to give them a shot and see what happens.

Posted by: Curbandgutter Jul 13 2016, 10:41 AM

Well look at what came it today. The parts look to be first rate. Everything is USA made with the exception of a wand piece that is made in Germany. The company told me that they stand by their product and that if I'm not happy with the results that they will take it back. We will see. Supposedly they were able to do 1 sf per 1 min and 15 secs. Not bad at all.

Well chassis table is complete. I measured it with a survey grade level and it is straight to 1/64th or 15 thousands of an inch. Now I can start about with actually working on the 914 rather than building all of the infrastructure (Rotisserie, Chassis Table, Sand Blast Cabinet). I guess I could have done it on the concrete floor and then have a twisted frame. But I couldn't live with myself. Rather, I'm doing it this way though because I just can't do this not knowing if my work is straight. However I have 3 weddings to attend in the next 2 months so my weekends are going to be used up in nonsense confused24.gif confused24.gif cause you know where I would rather be.

The order of work will be as follows.

First load 996 and measure and do a twist test.

second wet sand blast 914 on rotisserie

repair rust and epoxy primer

fourth put 914 on chassis table and do baseline twist test then start building tube chassis

It all depends on what you want to get out of it.

The clamping jack stands sound like a good idea you're most concerned with seeing changes in chassis stiffness and comparing to your FEA model. It's certainly easier than making solid shocks and hub adapters to clamp to the table and would produce really interesting data. I would love to see how close the FEA comes to actual!

On the other hand, it doesn't give you a great feeling on the stiffness of the whole system. I like to think of the chassis as a huge bracket which holds the suspension together; basically something that connects the dots. The most important reason to have a stiff chassis (besides impact safety which is a whole other design arena) is to remove an additional "spring" from your suspension. A flexy chassis can make suspension tuning difficult since it is sometimes tough to tune around that unknown spring. I did hub connections for my twist tests because I wanted hub-to-hub stiffness to understand the whole system. There can be a shocking amount of compliance in suspension mounts and components which you will miss if just doing a pure chassis twist. I have read that OEMs spend millions of dollars making sure mounting compliance is minimizes which is something the normal person isn't able to do.

Since you're keeping the stock suspension measurements, perhaps making hub adapters which bolt to the table wouldn't be so bad since you could use them multiple times and on both chassis? Just thinking out loud. I really do like the clamping jack idea too, the above were jut things to think about. smile.gif

Those should do the trick! They can hold a stupid amount on i-beams so I don't see why they wouldn't work on a flange.

Your table is awesome BTW! I'm super jealous!

Posted by: Curbandgutter Jul 20 2016, 01:42 PM

JD74914 your responses are always so on the spot and I really do appreciate them. It is what makes these forums. With respect to the twist test incorporating the compliance in the bushings, tie rods, etc., I agree wholeheartedly. However, what I am trying to do is to get a chassis stiffness so that I know how to set up the springs. My current 996 suspension needs new bushings and ball joints, so checking it in this fashion will be counterproductive for my purposes. As you may already know, a rule of thumb is that if your suspension stiffness is more than 10% of the chassis stiffness, then a portion of the chassis will be flexing and absorbing the loads instead of it going into the springs and dampeners. This condition will give a horrible ride and will cause premature cracks in the chassis. I suspect that this happens quite often when people put a really stiff spring on a stock 914 chassis. As would be my case if I just used the springs off of a car that weighs 3274 lbs and placed them in a car that weighs 2100 lbs.

The chassis torsional stiffness that I will check will be:

1) The baseline existing 914;
2) The 914 with the longs stiffened;
3) The 914 with the steel roll cage;
4) The 996 in stock form (oh oh).

My intent is to help other teener's so that they can see if stiffening the longs truly works. And if so, how well? It will be very interesting to me and to others, I suspect.

I've been reading that a typical torsional stiffness for a sports car is somewhere between 10000 and 20000 ft-lbs/degree. Also, F1 cars are much higher than 20,000 ft-lbs/degree.

I hope to load the 996 on the chassis table this weekend. Them I'm off camping to Sequoia so I won't be updating for about one week.

BTW I really did like the way the chassis table turned out. It's nice to know that what you are basing everything off of is straight and true. beerchug.gif

Posted by: Curbandgutter Jul 21 2016, 10:31 PM

Well the 996 is up on the chassis table. I was surprised to find that it had a twist of 1" in the frame. Wow I wonder how this thing handled? I wonder how it got that twist? I don't see evidence of a major wreck? confused24.gif confused24.gif

76-914 That has to be it. The fire was centered at the left rear corner and that's where the twist is. And here I am asking the stupid questions to the obvious answer.

Chris H. Yes I love the way they did it. Interesting to note that they are set up to exhaust UNDER THE CAR. I figured out a way to use all three in my design. I want the front trunk to be completely useful.

Frames do some pretty weird things when highly heated, especially if they haven't been previously stress relieved. Moving that far is pretty shocking.

Glad my comments are helpful in some way. smile.gif

The 10% rule is good, you figure it keeps your chassis an order of magnitude stiffer so the end effect of its flexing is second order on the overall system. That said, I wouldn't base spring setup off chassis stiffness. What people normally do is decide on a suspension stiffness (say 1 deg/g) and then back out the wheel rate then spring rate, and then make sure their chassis is a stiff enough spring to be ignored.

Ride and handling doesn't have to be poor with a flexy chassis; think about how well some superkarts perform. From what I've read, some of the current F1000 cars also use the chassis stiffness as a tuning knob as well. In a 914 with stiff springs the flexible chassis is definitely bad because of fatigue failures like you noted.

I'm very interested to see as well. In a rust-free car I'm not sure there is actually much benefit to long-stiffening with the Engman/Maddog doublers since the area moment of inertia increase is fairly low. On my car I made the longs deeper (well, on the side I'm finished with at least haha) to gain the h^3 advantage in bending stiffness.

I've been reading that a typical torsional stiffness for a sports car is somewhere between 1000 and 2000 ft-lbs/degree. Also, F1 cars can be as high as 20,000 ft-lbs/degree.


I believe these numbers are a little low. We always shot for at least 1500-2000 ft-lbs/deg on our lightly spring formula cars. Just to provide a Porsche comparison, here is some stiffness information I saved from somewhere a few years ago:

Porsche 996 Turbo (early): 9,957 ft-lbs/deg or 13,500 Nm/deg
Porsche 959: 9,515 ft-lbs/deg or 12,900 Nm/deg
Porsche Carrera GT: 19,177 ft-lbs/deg or 26,000Nm/degree

The Lotus Esprit is known for being pretty flexy and is said to be about 4315 ft-lbs/deg.

Current F1 cars I believe are currently much stiffer, though some may also be using their chassis as sprung members; the modeling you can do with $100M+ is pretty crazy. laugh.gif

The numbers above might not be correct since I can't remember the source, but give a little perspective. It should be really interesting to see what your 996 looks like!

Just make sure you keep the suction tube on top of the wand and dont point it up.

Once I got water in the media suction tube it was a bitch to get clean.

And the Pressure ratings for the washer to use is minimum. Mine was adequate ate 3500 psi and 4 gpm

Posted by: jd74914 Jul 22 2016, 11:58 AM

Bet the twist was from when the fire hose quenched the fire; the sudden temperature change probably sucked it in like you would use a torch and rag to suck in a body panel.

Posted by: Curbandgutter Jul 22 2016, 03:58 PM

The mystery twist has been discovered. Note to self make sure all jack stands are set to the same height. headbang.gif headbang.gif headbang.gif Frame is straight. This is great news since I need to measure the suspension cradle points on the 996 to transfer them to the 914.

Posted by: Curbandgutter Jul 22 2016, 04:15 PM

cwpeden Yes thanks for the heads up.

jd74914 i'm wondering how much benefit it would be to use the Engman and then add a strip of 1/8" flat stock on the top and bottom flange. That would add quite a bit more to the moment of inertia. The section modulus would be much better than the metal along the sides of the stiffener kit. I suspect that the Engman kit gives more rotational stiffness than bending stiffness though. We will see.

Posted by: Curbandgutter Jul 22 2016, 07:12 PM

Well I finished measuring the 996 suspension cradle points. Here is how I did it.

First I laser plummet the bolt

This is the digital dial indicator that I usedAttached Image

Here is how it triggers the dial indicator Attached Image

I added 100 lbs (2 -45's and a 10) at a distance of 11.375' This created 1137.5'-lbs of torque. Crazy deflection in the 2x2 but it was still only 50% stressed.Attached Image

Well this weekend member CSDILLIGAF and I will be making the nest for the suspension cradle. He's doing the same project so we'll work on the suspension and frame portions, and who knows what else? It's very helpful to have someone such as him working along side with me. According to my count this will be his 3rd successful Frankenstein transplant. He's the one that did a full 993 suspension on a tube chassis 914. From what I understand his 914 currently races in a very famous race and does very well. I love these 914's they are an incredible platform to work with.

Posted by: Curbandgutter Aug 13 2016, 07:57 PM

Well here is the suspension nest or fixture as some call it. CSDilligaf came over and we hit it for 8 hours straight. Only stopped of for a carnitas burrito, with rice and beans and all the fixins. Couldn't have done it so fast without CSFilligaf. It was nice to bounce ideas off each other as we put this thing together. Thank you for the input, work and the sweet bushings that you machined. Really pleased with the way it's coming out. It is almost complete as we only need to add the strut tower locations and finish welding a couple of more beads and cross bracing. After this, I can start building the frame for the 914 with this suspension nest centered and elevated within the shell of the 914. Enjoy the pics.

NS914 Thank you for your kind words. This build would have been very difficult 20 years ago due to knowledge being bottled up in some guru's head and not being able to be shared with no more than those within physical proximity. However, now with the "information superhighway", all we have to do is to research online and fill in our void areas with the specialized knowledge of others. This truly is a great time to be doing projects such as this since one can pull from the collective knowledge of the online community. Trust me we all learn from each other.

Back to the project now. I'm tying in the strut towers today and will have pictures up later. After that....the suspension fixture will be complete. Next step will be to strip the 914 and epoxy primer. I'm using the epoxy primer from a company called SPI. Then pull the 996 of the chassis table and insert 914 onto suspension fixture. Then the fun will start. The rotisserie, the chassis table and suspension fixture was only preparation to work the on the 914.

Well the 996 is finally off the nest and no longer needed. Big milestone for me. cheer.gif cheer.gif I'm blasting the 914 this weekend and epoxy primering it.

Well I started to wet blast the 914 and I ran out of sand. I've already used 2000 LBS. I think that I can get away with another 5 bags but I'll just get 10 just in case. Sand is cheap. Here is the video

Hi, what set up are you using for wet blasting? I think I bought a similar set up: http://www.globalindustrial.com/p/outdoor-grounds-maintenance/pressure-washers/accessories/mtm-5000-psi-industrial-sand-blast-kit?infoParam.campaignId=T9F&gclid=COCzkNyi584CFcFbhgod4vUAMA

but I am definitely not getting the same pressure you are. I'm using a Costco 2,600PSI pressure washer so its probably more like 2,000psi (maybe) and I was having a lot of trouble with clogged lines. If I kept blasting and had someone making sure the pick up tube was always in sand and the pick up hose flowing down to the nozzle then it was ok. The minute I stopped to looked at my progress the sand would clog though.

Posted by: Curbandgutter Aug 29 2016, 01:52 PM

I'm using the Power Eagle set up. I blew by 2000 lbs of sand and no clog ever. I would dump 300 lbs (3 bags) of sand into a 35 gal trash container. Then I covered to keep the sand dry and clean of debris. I absolutely loved the performance. It wasn't cheap though. It cost $300. However, it did not clog once and I even turned it upside down. I am using a Dewalt 4200 PIS with 4 GPM. Sand is #30 silica sand.

Thanks for the info. Yeah I think my nozzle is basically the same. I think the bigger pressure washer is key though. I'll try renting a bigger one when I get going again. Your Build looks great! I'm going the V8 route as well.

Yes I was very happy with the performance. It will probably take another 2 hours. For a total of 7 hours and 2500 lbs of sand. Let me tell you though it is the messiest job you will ever do. It's best to do in an open field or in an enclosure. Definitely not something to do in your shop or in your driveway. I'm on 2 1/2 acres with no neighbors so it worked out for me.

Posted by: Curbandgutter Sep 3 2016, 04:31 PM

Well I finished epoxy primering the 914. The next step will be to mount onto the chassis table, take some twist measurements and start building the tube chassis. I will be replacing the entire floor. It's just too banged up and rusty to mess with. I will also be removing almost the entire rear half. The entire rear half will be in steel tube and rear half of the body will be bolted to the tube chassis. Found 4 rust areas that I will need to repair. That can wait as they are not in the way of the tube chassis.

Well CSDilligaf came over today and we did the twist testing on the 914. The final numbers are in! The 996 C4 Cabriolet has stiffness of 4,568 '#/Degree. The 914 has a stiffness of 3,326 '#/Degree. So the 996 C4 Cabriolet is 37% stiffer in torsion than the 914. Makes sense, since you'd think that the newer Porsche should be stiffer than the 914, which was built with technology of the 60's. The next step is to place the 914 on the suspension nest and start building the tube frame. I was thinking of stiffening the longs with the Engmann kit, but I'm steering away from that. I will be stiffening the "longs" with a truss system built inside of the longs. That will be the first order of work. I will twist test again at that point and see what improvement we get.

As far as trying to see how well the Engman works (inside reinforcing) or Mayeur (outside reinforcing), bring your car over and we will twist it. Have to wait until I'm done with my car though.

Steel for chassis is coming in tomorrow. Going to build 6 turnbuckle braces to square up driver compartment before I get started. Should have nest in place this week as well. Let the chassis building begin. cheer.gif cheer.gif

Posted by: Curbandgutter Sep 16 2016, 07:50 AM

Well..........this officially marks the point of no return. Up to this point the 914 could have easily been turned into a restored stock......but now the fork in the road has been reached and I'm taking the "road less traveled". Started to cut up the engine and transmission well. Planning on installing nest tomorrow and will start with "upgrading" the longs first. I couldn't believe how much sand was in the longs. The left long had about a large coffee can of sand in it. I don't know where it could come from since the left did not have any corrosion. On the other hand the right long, the one with the hell hole, that one only had about a up of sand in it? You would expect it to be the other way around. Also, the left long had some fibrous cotton like material inside of it? Anybody have an idea what this is?

So,it's true then,all 914s rust from the inside out,as well as outside in!
They get it from all sides,every direction.
The material found inside is the stuff that absorbs the moisture,inflicting it on the unprotected steel.
The horror.

That cutting and chopping with the plasma is what I've had in mind for the minor stretch,to accommodate the longer engines.
This is getting interesting.Kudos.

Thanks veekry9. After seeing the "surface" rust inside of the longs......I would encourage everyone to stick some of the Eastwood internal frame coating inside. These things rust from the inside out as well as the outside in.

The 914 chassis (body) is full of strategically placed weep holes; as such, I suspect moisture and small debris enter through them and start the corrosion process...over many years, of course.

The heater tubes inside the longs are non-metallic and insulated. My guess is the tube in the left long is broken / deteriorated. So any sand that went in the left rear or cabin heater tubes didn't leaked out of the internal tube and went into the long. On the right long the sand went through the tube and out the other end.

I taped the heater tubes so that sand would not get it. It had to get in there some other way.....and I'm not exaggerating when I say that it was enough to fill a large coffee can.

Hey Cracker w00t.gif but yes safety first. agree.gif Anyway I completed gutting out the rear (phase 1). Phase 2 will be remove the inner fender well weld rear deck lid in place and cut quarter panels and make it tilt back for easy maintenace smile.gif smile.gif I also removed the warm air tubes and boy was that tough. They are basically two dryer vent tubes withing each other and insulated with cotton. With the air tubes out I was able to remove all of the sand from the longs. Unbelievable amount of sand. Now I know why they say that you will never get all of the sand out!! In my case I did though. shades.gif I'm also going to take the opportunity to treat the inside of the longs to that eastwood rust converter. I'm hoping to install suspension jig later today and then start reinforcing the longs with the truss idea.

Since you're MIG welding it might not help too much, but it has helped me while TIG welding so I thought I'd share...Apologies in advance if you've heard this before, etc. smile.gif

If you drill a small hole at each tube junction so the whole cage is one single volume, you can back purge and the quality of the welds is much nicer. Even without purging, the holes let any of the smoke from oil in the tubes move so you don't get any blowouts from pressure buildup while heating and the welds tend to be cleaner.

Hey Jim....yes JD2 model 32. That's good advice on the back purging. I will save that for when I do the headers. Yes you're right I'm MIG welding the frame so no back purging required.

Yes that is a good suggestion. I ruined 2 hoops (the rear "easy one")l, but I just need to cut the bends off and then I have material for the webs. But yes after I ruined two hoops I learned the error of my ways and was able to do the A pillar hoop in one try. If you notice the A pillar hoop is complex in that it has an offset bend and it also has a slight arch that follows the roof line. That arch is not in the plane of the windshield it is twisted about 47 degrees from the plane of the windshield. It was tricky but I did it and am satisfied with the result.

I was always taught to drill tubes when welding, otherwise you run the risk of making it a pressurized vessel and it may blow out. Molten Metal is not a fun shower. sad.gif

Here are my rules for back purging from the old school welders I used to work with (these were aircraft welders who only wire brushed in one direction, degrease before and after brushing, etc.):

- 100% of the time if TIG welding carbon steel, stainless, or titanium tubing (just as you would if welding piping or pressure vessels).
- No back purging for aluminum tubing
- Typically no back purging for MIG welding, though it does help on thin tubing. If someone else is paying for the gas absolutely back purge. laugh.gif

Sorry for the hijack Rudy. smile.gif

Posted by: Curbandgutter Oct 25 2016, 03:42 PM

No highjacking just good information for those that are following the thread. And yes, I agree no need to backpurge for mig on mild steel. Also, I have never heard of the situation where the tube becomes a pressure vessel? Wow that is amazing and I am having a hard time believing it. One would think that the conditions for it would have to be a one in a million. It's possible but not probable, practically speaking.

Posted by: jd74914 Oct 25 2016, 09:29 PM

While certainly not pressure vessel grade, I've had melt blowout problems with smaller sealed tubes while TIGing. We're talking about 1" tubing of about a foot or little longer length. While not dangerous it's certainly inconvenient.

Posted by: Curbandgutter Oct 26 2016, 07:39 PM

Whats your thinking behind the placement of those upper bars connecting the front and rear hoops?

Im concerned that they are placed too far inward which could put them directly over the drivers head instead of off to the side. Is there a reason you haven't placed them off to the corners? Theres not a lot of headroom for drivers & passengers as it is in these cars, you might consider putting them as far off to the corners as possible.

Loving the build so far, keep the pictures coming!

Yes, the lengthening came about from thinking how this would give me a better straight line stability. Two inches is a number that I can sneak in and still look like a regular teener. This gives me more room in the engine compartment and allows the cv axles to line up better with the transaxle.

Move them inboard and you can build the B B tribute 914. After all their 928 was a targa also.

Hahaha. I remember those seats. I think Recaro made those?? In seriousness, I'm not too sure I'm going to use the tie bars for the a and b pillars. If they give me a 5% increase in stiffness then I'll use them. Otherwise they're out.

You're too funny, seems like the sarcasm went over both of our heads. poke.gif I'm actually 6'. It is almost impossible to "read into" sarcasm as you can see smile.gif smile.gif .

Anyway, I was able to get the suspension jig lined up under the 914. I stretched the wheelbase 3". I also raised the suspension jig 3/4" into the 914 thereby lowering the ride height by 3/4" as compared to a stock 996. The cool thing about this is that by lowering it this way, it will retain the stock 996 ride but in a lowered stance and the ride quality will be completely unaffected. Attached are the pictures of the suspension jig in place.

Ha ha ha, yes unfair advantage. I'm not retired however. Since I'm self employed, I sometimes take the time when I need a "mental pressure" holiday. Working on the 914 is a stress reliever for me. And yes aren't these 914s incredible platforms to modify? I've enjoyed seeing your's and Tony's post as well. By the way. the wheelbase is already extended, it's just that you won't be able to see it until the suspension is installed. I'm going to have to modify the rear 916 flares. I think it's going to have a look similar to the Audi R8 in the rear. It will still hold it's distinctive 914 look though. I want this to look like the "next level" 916. It will be about wider that than a typical 916 and the wheelbase will be 3" longer. I'm super excited with the way it's coming together. Thanks for the encouragement.

Yes it might have been easier to paste body panels on a tube frame. lol-2.gif

Naaah not 3,500lbs. If I wanted it that heavy I would have just as well gone full bore and tried for a section 179 IRS code exemption. I have a running total of how much weight I have taken off and how much I am adding. Let's just say that it will be somewhere around the weight of your car.

Engine is a coyote 5.0 . Transaxle is currently a G96 off a 996 but I am considering going with a 996 TT transaxle.

Thanks for the positive comments......I really appreciate them. I swear "the car" will be undeniably a 914. After this round I need to take the sheet metal off the inside of the rear fenders. The rear quarter panel and back trunk will swing up and back to expose all of the steel tube chassis, aluminum suspension, motor transaxle and 335 rears. I'm hoping to complete the front end today.

Here is the reinforcement from the factory that many use to feed water lines through. Notice the crazy amount of sand inside of these? Also....the corrosion. Put some paint inside of these whenever you can.

Posted by: csdilligaf Nov 21 2016, 12:23 PM

I wondered about needing to shorten the struts. Yours are already adjustable and may in fact go down enough to fit. I am working on shortening my factory ones first if possible. Hmmm! Brisket looks good!

Posted by: Curbandgutter Nov 21 2016, 04:07 PM

I'm not sure if the Gurney bubble would take away from the lines of the 914. But yes it is a solution. However I think that with my coil overs and some machining I may not need the bubbles.

I see, pun intended. Not feeling it though. I wonder what suspension that car has that it would need that??

Posted by: Curbandgutter Nov 23 2016, 07:55 PM

So I've been thinking and came to the preliminary hunch/suspicion that I can't just cut the strut tower height without changing the instantaneous roll center. This would be horrible and would affect the dynamics of the car. I'm going to do some calculations and figure it out. However I'm thinking that I may be confined to keeping the struts whee I have them now and then figure out how to implement it into the car. Anybody have some input????

Posted by: FL 000 Nov 23 2016, 08:19 PM

Isn't the instantaneous roll center determined by the upper and lower control arm geometry? If that is the case I would think strut tower height is independent of it.

Posted by: Curbandgutter Nov 23 2016, 11:48 PM

I believe that with the Mc Pherson struts you don't have an upper wishbone. The top of the strut tower is considered the upper wishbone location then you hold a right angle at that location and intersect it with the angle of the lower "a" arm.

see this article

https://balancemotorsport.co.uk/suspension-geometry

It appears that as I lower the strut tower it will raise my roll center. This may not be a bad thing, since depending on where the cg is, it may create a smaller moment arm between the roll center and the center of gravity. If this is the case the car will have less lean in the front end. That may help with creating less understeer. I have to think it through. I have to calc what my cg is up front and then what the 996 roll center is and then what the roll center will be if I lower the strut tower elevation. I need to do some calculations before I make a decision.

Posted by: csdilligaf Nov 24 2016, 10:16 AM

I think shortening the length of the strut along its axis will have much less effect than the article shows when the car is simply lowered. By lowering the car the wishbone angle is changed thus effecting the Roll Center. It does not change all that much if you shorten the strut a few inches with out changing the Steering axis inclination. It will change the Instantaneous Center(virtual Point) and I think the rest would still be the same? But I do not have any strut calculation engine so it is just my gut feeling. I just think it has to end up better than the guys who take a 996 and slam it. It will be interesting to see what your calculations come up with.

Posted by: Curbandgutter Nov 24 2016, 04:28 PM

Shortening the strut will be a step in the positive direction as is will raise the IRC approximately 5/8". Good cheer.gif cheer.gif cheer.gif I wasn't feeling those Gurney bubbles at all.

The weather let up a bit and I was able to sneak in some hours into tying the strut towers in. By the way I am really giving it some heavy consideration into changing engines.

A short passage from a book I think I'll write about Rudy:

"It will produce 600 HP so its where I want to be." He said this casually, as though this level of power was commonplace, even easily attained or available without much planning. He was, as everyone already knew, power hungry. He would come to look at his initial 600hp as "a decent starting point". Eventually, he printed t-shirts with this slogan on the front pocket:

If more is good then too much is just enough!

On the back was printed "I'd rather be sideways".

You asked Rudy... shades.gif

I am not a fan of the Audi 4.2 RS4 engine...I saw a nice conversion done into a Boxster race car - very underwhelming. It is low on torque and wasn't competitive either...honestly, I don't care for the sound too. There is a high-price to pay when squeezing big power out of small displacement motors - I know all about them, first hand. Synonymous with hand-grenade.

Remember, you asked!

PS: Although both heavy and large - I've thought the GTR TT v-6 would be a nice addition to the 914. Audi have already been done...

PS #2: I'm digging your progress - great job!

Posted by: Andyrew Jan 16 2017, 12:13 AM

4.2 tt rs4 motor? Thats a lot of weight to make that much power.

Its a compact and complicated setup but 600hp is easily made on that setup and it should be extremely torquey.

I think if It were me it would either be the rs4 NA v8 or a S8 4.2 motor for about 360hp to be more economical.

If I wanted to go turbos again with an auto motor I would go 2.7 built with gt28 turbos or KO4 hybrid turbos. That would put a power range from 325-800hp.

Posted by: csdilligaf Jan 16 2017, 08:19 AM

Andyrew, I think you nailed it with the Audi 2.7TT.

Posted by: jd74914 Jan 16 2017, 08:29 AM

Nice strut towers Rudy! They look like really stiff nodes! smile.gif

The Audi 2.7TT might be a good motor if you want to keep it German. Otherwise a Subaru EG33 or EZ30R with some turbos might work well too-and they'd help lower your CG to boot.

Why are you thinking of moving away from the Coyote? AFAIK they are pretty robust motors to ~650hp (forced induction).

Posted by: Cracker Jan 16 2017, 08:51 AM

I would love to see a small displacement motor - probably a six-cylinder - with quad turbos - since you are ambitious. A target of 600-800 hp at the crank would be fantastic. I have changed my tune on what is "usable in a 914" since my car is so composed with only 590 hp...my car with a 275 rear could hold another 100 easily. Looking forward to what you choose - even if it is an RS4 variant. Cheers.

Posted by: Andyrew Jan 16 2017, 09:46 AM

No need for extra complexity with extra turbos. Thats not going to gain power, just response. The 2.7 is plenty responsive with appropriately sized turbos or even just a single turbo like a precision 6262.

The biggest thing to do with turbo cars is pick the right turbo/s for the motor to eliminate boost lag and pick turbos that will efficiently work within the power range your looking for. From there you build the motor to handle the power, make it efficient and then start pumping in boost, timing, and fuel to make power.

My turbo system is a hair lagy but its only a 1.8L displacement, my efficient boost pressure range is 10-35psi letting me tune my boost curve how I want it. I can either turn the timing and boost up down low for the most torque I can make which will blow the tires off as quickly as possible and break things. Or I can give it medium hit and ramp the boost up as it gets higher in the RPM or time in gear to allow for more potential traction yet higher overall acceleration.

Posted by: Cracker Jan 16 2017, 12:32 PM

I do not know Rudy personally (but anyone taking this on - I'd like to meet) but through watching his build (much like Chris too) - it appears he wants to chart new ground - so to speak. The added complexity is the bait to chase - not the obstacle to be avoided - for the rare bird like Rudy that is! JMHO

Twin turbo's, superchargers, vee-eights, etc have all been done adnauseam - a quad turbo set-up on a hot v-6 with DI would be epic. If Rudy isn't that motivated to build something truly unique, I get it. I am not (but it would be otherworldly!)...

"I am not a fan of the Audi 4.2 RS4 engine" neither am I. CSDILLIGAF has succeeded into talking me into the Audi 2.7 V6 twin turbo.

jd74914
I thought you'd like those strut towers. I still need to add some gussets. I'm kind of steering away from the coyote for a couple of reasons. The coyote is a great motor but Chip has swayed me into the 2.7 audi because you don' t need adapters and special clutch assemblies. And, I like the way that turbo'd cars pull. Additionally since we will be doing the same exact car, we can brainstorm and have a better chance of success.

I totally understand the CG issue but I just don't like the way that 4 bangers sound. stirthepot.gif stirthepot.gif

Cracker
Thanks for the compliments. You and Tigaboy are so hilarious in your writing styles.....I love it. Sorry to let you down though, but no quad turbos, two is enough. I think that the pull on the 2.7 will be enough to give passengers vertigo. I'm hoping that the car will get better traction with a controlled power band up high than down low where it will just cause wheel spin. It's nice to know from real world experience such as yours, that the 914 can handle an additional 100 hp over your 590. Wow that says so much for the amount of performance that is locked up in these little cars that we love. I look at the fact that my car's track is now 5 inches wider, the wheelbase is now 3 inches longer than a stock 914 but 7 inches longer than a 911 and a chassis that will be at least three times as stiff as a 911 and weighing as little as a stock 914, I feel confident that it will not disappoint. It is quite telling that the new 911 is the same wheel base as a 914. shades.gif

Andyrew
The 2.7 will have the twin RS6 RS turbos.

I'm getting really close to bolting up the suspension. Just need a couple of gussets and the roll bar diagonal and it will be ready for the suspension. Then I'll replace the floor and close up all of the holes I made to insert chassis into the chassis. I will be adding shear connections along the floor pan, the dash and the targa to transfer loads between the chassis plate elements and the tube chassis axial members. In other words tie both chassis together so that they supplement each other where the other is weak.

I thought you'd like those strut towers. I still need to add some gussets. I'm kind of steering away from the coyote for a couple of reasons. The coyote is a great motor but Chip has swayed me into the 2.7 audi because you don' t need adapters and special clutch assemblies. And, I like the way that turbo'd cars pull. Additionally since we will be doing the same exact car, we can brainstorm and have a better chance of success.

I totally understand the CG issue but I just don't like the way that 4 bangers sound. stirthepot.gif stirthepot.gif

....

I'm getting really close to bolting up the suspension. Just need a couple of gussets and the roll bar diagonal and it will be ready for the suspension. Then I'll replace the floor and close up all of the holes I made to insert chassis into the chassis. I will be adding shear connections along the floor pan, the dash and the targa to transfer loads between the chassis plate elements and the tube chassis axial members.

As odd as it sounds they are my favorite part of the car! beerchug.gif

That makes perfect sense. Using components which are designed from the factory to bolt together is much better. I've personally never been really impressed with the adapter plates/flywheels-too finicky and too unique to the combination. Having two test mules should make it much easier to wring out all of the problems too.

ar15.gif laugh.gif Equal length headers fix that pesky noise issue...and make the 6's sound like 911's... rolleyes.gif

Can't wait to see the shear panels!!

Do you have any ideas on what a 2.7TT dyno plot might look like? Or your gear ratio's/final drive? Just curious as to what the tractive force curve might look like. If you have some numbers I can throw them into a spreadsheet I have and send it to you.

Posted by: Andyrew Jan 17 2017, 01:18 PM

2.7 with RS6's should be a lot of fun. Are you going to get the JHM one's?

What engine management and fuel are you going to go with? We could talk Audi engines all day...

It will be interesting to see how you build the motor, what you do with fueling, engine management, tuning, clutch, ect ect.

The 2.7 is a nice sounding engine, I will give you that smile.gif


Dyno for comparison.

Yes the JHMotorsports ones. By the way that looks like it may be the dyno sheet for the JHMotorsports RS6 car? Is that it? From reading your posts and the impressive tuning that you have done it looks like you will be an excellent source of input on the Audi stuff.

JD74914 here are the gear ratios

1st gear 3.307
2nd gear 1.95
3rd gear 1.407
4th gear 1.133
5th gear 0.972
6th gear 0.822
Final drive 3.875

Rear tire will be 335/30-18

Put it in your spreadsheet or if you can, send me the spreadsheet and I'll post the numbers.

Posted by: csdilligaf Jan 17 2017, 01:59 PM

Rudy, the gear ratio's on the G87.21 have taller 1st and 2nd gears as listed on the California Motorsports page. They are 3.307 for 1st and 1.95 for second. That's another reason to use the G87.21.
Plus your tire is a little taller than mine. Yours is 25.9 so you can stretch out the revs more than mine.

JD74914 I calculated the tractive force based on the Boxter S G87.21 gear ratios and the S4 Stage 3 Dyno plot and this is what I got. Seems like a smooth transition. Looks like Porsche knows what they are doing in selection the gear ratios.

That is a nice smooth parabolic curve-perfect! That's what I've noticed too. If you plot curves from many manufacturers there are some big gaps, but Porsche and Subaru seem to have the gear selection thing down pretty good (for the ideal "go-fast-car" case).

I pulled it last night too and got a very similar curve...sorry I didn't get a chance to post to save you the work. I pulled a number of gear ratios from CM's website and the G87.21 really does seem like a good choice. It's a shame first gear isn't slightly longer, though this seems to be a "problem" in almost all gear boxes (it's really bad in sport bikes).

Copied this from my thread...

QUOTE(Curbandgutter @ Jan 18 2017, 12:00 AM) *

Jim, your tractive force spreadsheet proves that if you shift at max torque you will drop the tractive force substantially. It proves that shifting is better near max horsepower. I just did a spreadsheet for my car. Very interesting information. Thanks for illuminating me.

Yeah, it's a rather interesting plot since it brings out things you usually wouldn't think about. It also does a good job of justifying peakier, higher overall power engines vs. these flat torque curve monsters. Glad it could be of use! smile.gif

Wow I though that the rear shock towers would take me about an hour each and it took a full 10-hour day to complete both! Anyway here are pictures of the rear shock towers. I took a piece of 6" channel and made a paper template and cut with plasma cutter. Ohh...I'm picking up donor car today. It is a running Audi S4 with 130K miles. Picking it up in Van Nuys tonight. The only major thing left to purchase will be a boxster transaxle. I was hoping to be able to bolt up suspension but that will have to wait until next weekend.

What are your plans for intercooling -- air/air or water/air?

Posted by: Curbandgutter Jan 31 2017, 11:17 AM

For simplicity ( I know it's an oxymoron for this build) I am going to use the factory setup. I think that it is air/air. Since I am planning to open up the back end 2 1/2" on each side to accommodate the wider 996 track, I will take advantage of that and place an intercooler on each side but most likely 50% larger and mounted vertically. I will fold the rear 1/4 panel into them and create a reverse scoop to drag air into them. I plan on venting out through the rear in between the tail lights with some type of expanded metal. Maybe like the one that is on the engine lid.

Posted by: Andyrew Jan 31 2017, 11:55 AM

Factory intercoolers are air to air and are not very efficient. They make thicker intercoolers specifically for the S4, specifically chineese versions that are very affordable. Combine that with E85 or W/M injection and you should be good for a considerable amount of HP.


I would go something a hair larger like this if your considering staying air to air.
http://www.ebay.com/itm/Rev9-Turbo-Side-Mount-Bolt-On-Intercooler-For-300zx-Z32-90-96-Fairlady-Z-VG30-/381440476746?hash=item58cf9fc64a:g:zAMAAOSwAYtWIXMO&vxp=mtr

But you would probably be better off going with a pair of bar air to water intercoolers and just mount a single large radiator in the fender.

Noticed forged diverter valves, Thats a plus smile.gif

Pull the ECU and see if there are any markings on it. I bet at the very least this car was tuned, probably sell that ecu for an easy buck if your going a custom engine management system.

Posted by: csdilligaf Jan 31 2017, 12:22 PM

There really is not an affordable option for a stand alone engine management for this motor. There are people who tried with a $5K version or more and had nothing but trouble and never got it to work right. We want to build a car, not take a year to learn what others already know and are good at. The factory ECU has a huge following and tuners with the education and skill it takes to hack and do what ever you want are plentiful. I have found Motoza Performance to be the best, easiest, most helpful and cost effective. For around $400-$500 they give you the software to reflash the ECU, the cable to do so from a laptop and OBD2 port and the first version with the basic tune. This allows you to get up and running and run the data logging that gets emailed to them and they will tweek things until you are happy. If later you go up to bigger turbo's or go to E85 you just pay the difference of the two stages pricing and they help you out again.

Posted by: Curbandgutter Jan 31 2017, 12:46 PM

Andrew thanks for your input. But yes we're sticking to stock engine management with tuners that work with them. Thanks for the info on those forged diverter valves, I didn't think they were stock but really didn't know what I was looking at. I have a lot of learning to do on this motor. I'm glad you're around so that I can glean information from you.

Megasquirt has been effectively utilized on that motor, but I agree the factory ECU is more than capable. I am utilizing the factory ECU as well and know it has and will support my setup just fine as I ramp up the power.

Seriously pull the ECU, Most tuners will mark it. You might find it tuned by a reputable tuner who will set you up on a big turbo file and give you advice on what you need injectors, fuel pump, maf, ect ect.

Custom intercooler is a fantastic way to go on a project of this nature. If you have the ability to weld aluminum I really think you should build a twin air to water intercooler setup in front of the engine (you will have plenty of room).
This will allow you to keep the intake plumbing short and in the engine bay vs having to shoot to both sides of the fenders. Should help with spool as well.

You can't go wrong with anything from Bell. If you need technical support Gerhard Schruf is awesome! I've bought air-to-air and air-to-water intercoolers from them a few times (industrial usage but really no difference from automotive) and their prices really aren't too bad considering the quality.

Lets go, start dropping in trans and that Audi is not gonna pull its own engine!

Posted by: csdilligaf Feb 22 2017, 09:52 AM

I just got back from California MotorSports in Lake Havasu Arizona after having them install the Wavetech LSD in the Cayman S 6 speed. I have been working on mating the trans and engine so Rudy and I know what to expect. If I work out those details it will speed along the process for him and he can focus on other parts of the build.
I have a Fidanza aluminum flywheel and an RS4 clutch package. First there is a 1" thick spacer on the crank face of engines that came from an Automatic equipped car, I put steel rod in the holes and tapped it a little while going from hole to hole, popped right off. Warm up the flywheel so the hole grows enough to slip over the crank locating boss. The bolt holes will only line up one way, they are not equally spaced. If you warm the flywheel to about 180/200 degrees on a hot plate it will give you time to align it with a bolt or two before it tightens up. Use the 1mm thick shim from the automatics flex plate in the same location under the bolts to prevent galling and help torque to correct specs.
I will make a drill fixture plate with bushings so that three stud holes can be drilled and tapped along the bottom of the G87.21 trans making it fully bolted to the Audi 2.7T.
It appears that the Cayman S trans has a boss that needs to be drilled out for the crank sensor. The boss is in the same location as the Audi manual transmission and I have seen it done on an Audi swap into a Boxster S in the UK.
We will need to use the transmission spacer from the Audi automatic trans that is 7/16" thick. The RS4 clutch disk fits on the Cayman S spline and the pilot shaft fits into the pilot bearing perfectly.
Now we just need to figure out the Vehicle Speed Sensor. Maybe something mounted on the CV joint. It is a magnet pulse type. Rudy has one from his parts Audi and I purchased the sensor and the pulse ring new. The pulse ring is smaller than a CV joint so we may have to try and replicate the pulse some how. Any electrical engineer types out there that know how to figure it out? Here is the basics of it.

Maybe we can adapt the 996 abs sensor and reluctor ring to duplicate the pulse?

Posted by: Andyrew Feb 22 2017, 10:01 AM

Regarding your clutch. A standard B5 RS4 clutch isnt the hot ticket now adays. Apparently the B7 clutch pressure plate is that much better. This might require a custom flywheel, check into the S4 forums to find out what they are doing. If I swapped out my clutch again ( I have a stage 3 S4 clutch) I might go this route.


Regarding your VSS You could simply count the pulses on the stock VSS pickup, fab up that many 1/8-1/4" steel teeth and weld them onto your CV flange, then fab a mount for the VSS.

Posted by: csdilligaf Feb 22 2017, 10:27 AM

It may not be the hottest ticket but I think it will hold the power for now and was cheap. Now Rudy may want to look into that because I know he will be looking for more power than me. I will be at 375/400 with 550cc injectors and Ko4 turbos on E85. And may still have to go with something like the stage 3 like you have now. I just really like the ease of a build that is bolt together with no custom and expensive parts.
I have done the flange modification you mentioned for the VSS but it was on an LS swap and the sensor had the magnet in it and was an easy set up to do. It looks to me like the Audi VSS has the magnetic pick up in the reluctor wheel and if flips from North to South? I suppose I could use magnets in the flange this time and just flip them according to push and pull magnetic field?

I'm very surprised it's a magnetic ring. It looks like the magnets close a reed switch so to produce a square wave, so you could likely switch to a hall effect gear tooth sensor and use an 8 toothed wheel added to the outside of your CV boot, etc. rather than add magnets to something.

I'm very surprised it's a magnetic ring. It looks like the magnets close a reed switch so to produce a square wave, so you could likely switch to a hall effect gear tooth sensor and use an 8 toothed wheel added to the outside of your CV boot, etc. rather than add magnets to something.


I was thinking the same thing smile.gif

You could test it on a abs sensor before fabing it up to see if the voltages on the hall sensor read correctly in the ecu.

Coming from ignorance here...

Why would there be a separate vehicle speed sensor when there are ABS sensor and reluctor rings on all four corners of a 996?

Maybe, as stated earlier, the wave form is different.

It's a good question. In a perfect world they really shouldn't; vehicle speed should come from some combination of wheel speed sensors when so-equipped. Not sure of the VW/Audi/Porsche reason, but some cars have them because of the way the controls are divorced between ABS, traction control, dash, and engine. A communication bus will link all of the computers, but there can be a bit of latency or sharing problems in between legacy hardware pieces. Just speculation, but ABS controller isolation might be the primary reason. Or perhaps legacy engine management code, etc.

Posted by: Mark Garriott Feb 22 2017, 11:34 AM

Ah, yes. I remember hearing the early 986/996 had a 3 way ABS system that was virtually standalone.

Posted by: csdilligaf Feb 22 2017, 11:38 AM

Rudy has his to a point he could check that. He says its like 5" wider than the stock 914 but maybe he can verify. I'm out east of you in Alpine if you ever want to stop by and check out my build so far let me know.
I suspect we will have to figure the pulse/wave thing. I see on my axles that the ABS ring has like 80-100 teeth so with modification maybe something can work out there.

Posted by: Mark Garriott Feb 22 2017, 11:56 AM

Hi Chip,

I visited you a couple of times five or so years ago, to see your 993-based car.

I am glad to see you are still tinkering on 914s. I have since moved to Idaho. But I brought my 914 with me. Gotta change my profile...

Audi typically builds in some redundancy. Many sensors only drive the gauge cluster.

For example Audi uses two coolant temp sensors, one for the fan control unit an one for the ECU.

Posted by: csdilligaf Feb 22 2017, 12:16 PM

Andrew, When we get to that stage can we count on some help in the gauge cluster dept? We both are going to use the Audi one like you did. Looks close to the 914 and would nice to keep it. Did you have any warning lights that go off in the cluster or are they programed out by your tune? Like ABS, Check engine, air bag and the sort? I don't know what to expect really.

Posted by: Andyrew Feb 22 2017, 02:47 PM

ABS triggers a chime in the back of the cluster that I disconnected manually. Air bag light is on, but the check engine light doesnt come on as all the sensors not used have been coded out.

I'll be putting some resistors for the air bag light or simply remove the bulb. I plan on using the ABS stuff from the Audi so that light will stay in.

Easy peasy. The 951 guys use 996/Boxster ABS systems all of the time. The older Bosch ABS 5.3 systems (with 2 rows of pins) are standalone so you can run them pretty easily. All you really need besides the ABS valve/control block is the 4 wheel speeds and a power supply. By all reports they work pretty well for 3-channel ABS.

I'm planning on it actually... smile.gif

The audi ABS system is incorperated into the stability control system
It uses the steering wheel angle, the abs wheel speed as well as 2ea yaw sensors.
What it does is it has a pump that constantly primes the ABS box and when it senses a situation that it needs to apply brakes to a wheel it will, on top of that it is connected to the ecu so it can shut off throttle or reduce it as needed. Its a fully self contained system that only requires those parts and runs off a separate ecu. Since you have a full spare car I would suggest ripping out the wiring harness in tact and stripping all the non essentials off. Thats what I am doing.. I started with the dash and engine harness and. I have the body harness stripped mostly down.

Good luck! This was a primary part of my build. I designed my build to incorperate this as I feel the 914 could benefit from both abs and stability control at this performance level.

Jim I think I may just give the 996 ABS a look. Is this the system that I should be looking at? It is a 2 pin connector.

Posted by: Andyrew Feb 27 2017, 01:14 PM

That 2 pin connector is the ABS pump for the stability control system. Basically it primes the ABS box to allow for the system to hit any of the brakes at any time. Its similar to the Audi pump in design.

The first pic is the ABS box. That takes a multi pin connector, similar to the Audi. (See below)

Your going to have a 10x easier time if you use the Audi stuff as your donor chassis is already wired for it.

Posted by: jd74914 Feb 27 2017, 01:15 PM

Interesting-I haven't seen one like the second one before (note that I have almost no 996 knowledge). People call it the pre-pump? Not sure exactly what it does except that it's for PSM.

The one the 951 guys use is out of early Boxsters (and maybe 996s since it does have a 996 P/N) and looks like this:

Andrew beat me!

The thing I worry about using an Audi unit vs. Boxster is that the two must have different vehicle dynamics "models" built into them. They both seem to use essentially the same hardware, but I'm sure Bosch has each programmed for the specific vehicle. I'm not sure about Audi weight distribution, but the fact that it is AWD means that there is definitely a different front axle response model which likely has some corrections for reduced lateral grip while applying power. It might work great though-the engineer in me is a little conservative. laugh.gif

The way I see it, if race guys strip out the vehicle to weigh 1k lbs less than factory the ABS should perform the same. Stability control should perform the same.

I see the system responding to grip loss. Yes there are yaw sensors involved as well as steering angle but that will only tell the system where the car is trying to go and adjust throttle and brake in such a way to counter it.

The biggest thing that I wanted to make sure was correct for my vehicle was that I used the same size ABS teeth count for the rear as was OE for the system, so that if the system tries to read wheel speed and correct it wouldnt be dissimilar to anticipated wheel speed.

Same goes for the front of the vehicle. I run smaller overall tires in the front than the rear by a considerable margin. I would want the teeth count of the front ABS to match that ratio appropriately as the Audi runs the same size front to back.

So long as that is good, I imagine the system should be able to compensate for the weight/power balance differences.


Regarding AWD vs RWD and its limits for throttle imputs at the edge. An AWD based car has more mechanical grip on power ramp and therefore I would imagine that the base of the system would have a tendancy to oversteer on onset and then the system would bring it down when it noticed the rear wheel speed being significantly higher than the front.

Jim, yes I was thinking about that as well. I'm not sure if they have a vehicle dynamic model built into the ecu or it's purely a comparison between wheel speeds?

Andrew, I have both systems so I'm not sure which way to go yet.

Wow Andrew......good stuff!! Decisions decisions. If I go with the Audi steering wheel, then it will have the turning angle unit built in, the g meter is under the seat, wow seems like it may be something to really look into. It seems that the vehicle dynamics is not built in but rather it's a real time sensor system that is continually monitoring an that will aid in the anti lock braking but will also will also brake a single wheel to help the car in over steer and under steer conditions. I'll have to really think this through.

Well, this is a theoretical problem right?
ABS sensors on the wheel determine individual wheel speed. Open differentials on an AWD vehicle will have a mechanical torque based slip on the front to rear ratio, Left to right differentials will be open allowing for the wheel with the least amount of grip to spin, So if the right rear has the least amount of grip it will spin, however if the center differential has a 40/60 F/R split it will still send 40% of the power to the front allowing the vehicle to accelerate forward.

To determine body speed the wheel with the lowest wheel speed would be the most accurate in relation to road speed. Calculate the rotations of the wheel to the overall tire diameter can determine overall body speed.

Or did I misinterpret the question?

All wheels are spinning so none correctly give vehicle speed. The one spinning slowest may be most accurate, but you don't know if it's correct enough. From my understanding in ABS terms it likely is, ESC its unlikely.

Thinking about it really quickly it would seem that you have to back it out from the measured acceleration, some simplified tire/vehicle dynamics models, and engine outputs. Perhaps it really a iterative shooting procedure since it must happen real-time? Need to give this some more thought on my end...definitely not a trivial calculation. ESC is crazy complicated.

All wheels are spinning so none correctly give vehicle speed. The one spinning slowest may be most accurate, but you don't know if it's correct enough. From my understanding in ABS terms it likely is, ESC its unlikely.

Thinking about it really quickly it would seem that you have to back it out from the measured acceleration, some simplified tire/vehicle dynamics models, and engine outputs. Perhaps it really a iterative shooting procedure since it must happen real-time? Need to give this some more thought on my end...definitely not a trivial calculation. ESC is crazy complicated.

Sorry for the hijack Rudy. smile.gif


This is not a theoretical problem. In a slip based controller accurate knowledge of the body speed is critical and a good portion of the ECU capacity is used figuring it out. Andrew did well by getting to the slowest wheel as the best indicator of body speed and jd74914 identified the issue that best probably is not good enough for ESP.

Add this to the complexity of all of the other sensors and factors that obscure the reality of what the vehicle is doing or what the driver is requesting and hopefully you will come to the conclusion that it is not a system that can be swapped between vehicles. Years of effort go into adapting the system to each production vehicle.

Once it is adapted, things like programmable drift angles are fun engineering exercises!

Cheers,
Scott

Scott - I'll muddy up Rudy's thread (at least) one more time...I had taken a hard look at Bosch's Motorsports ABS M4 system/kit in the past. Most people whine about the cost - anything at the pointy end of development comes at a high price. What are you thoughts regarding programming/calibrating such a system to a 914 on slicks? The appealing upside to me was the adjustable slip that can be selected based upon a number of conditions and driver preferences. Until someone else surfaces with video of locking up the front brakes on a 914 at 165 mph (not something to be proud of, just experience) - I believe I am the only one with direct experience. I see the value of such a system near the limit - just not for a hot rod, doing hot rod things.

I really appreciate your consistency and dedication you have to referring to your 914 as a "hot rod"....whatever makes your insurance company happy I guess. poke.gif

As for the Motorsport ABS system. I have no direct experience with it but have friends that do and happened to be stuck on an airplane with one the other week and briefly discussed some issues they found at Daytona with the NSX GT3 project they were applying the system to. From my understanding the system has basic vehicle parameters that are setup and then the base calibrations are automatically set. There are several settings that can be selected from a dial switch that are fixed and should work for most drivers. There are one or two settings that can be calibrated, probably at a huge cost. The tables might be open...I can ask if you get serious.

Contrary popular belief, very few drivers if any, can consistently out brake a car with modern ABS. People will probably make fun of you until you blow by them in the braking zone. Go for it!

Scott

Scott - I was referring to Rudy's car...LOL! You are correct, however, I mainly just to stick that out there to poke at Bob Saville (who happens to have a legitimate 914 race car!).

I only have a hot rod. beer.gif

Thank you for your insight regarding the M4...I cannot offer an argument against it and it would make driving at the limit a whole lot easier - to mention the added confidence it would provide! The faster one drives, using technology to ease the drivers workload becomes more and more critical. No different than the go-fast gizmo's on my prototype buggy...

Well motor is out of the Audi. It was amazing how these things are packaged. True nightmare to work on in the Audi but won't be a problem in the 914. Heck I'll be able to walk into the engine compartment. Great motor, but the way it is shoved into the Audi, it sucks big time. You forget how short these Audi V6's are. It measures about 18 inches long. So it's about 6" shorter than an LS1 or Coyote. Makes sense since its 2 cylinders short.

^^^ av-943.gif av-943.gif av-943.gif Well I separated the Audi motor from the triptronic and weighed it with , alternator, power steering pump, air conditioner, Ac drier, full of oil, headers, turbo , electric harness and torque converter. It weighed......a little shy of 440 lbs. I wonder how much a wet and fully dressed LS motor weights. I need to compare apples to apples though. Therefore the LS motor must have flywheel, clutch, exhaust headers, all peripherals, electronics, fuel injection, and intake system. Has anyone weighed this or have good information on this??

Posted by: csdilligaf Mar 5 2017, 02:18 PM


So today's project was to get a drill fixture made so Rudy can have more bolts to hold the engine and trans together. I took the adapter plate and put it on my CMM to measure hole locations. Made the drill fixture with two locating pins in the alignment holes and four long drill bushings for the lower four holes that line up on the engine along with two hold down bolt holes. The Cayman S 6 speed has solid bosses at the correct location but Porsche does not drill them since the Cayman motor does not need them. Its nice that they are there though. Now we can use all of the bolt holes in the engine. I think it will be best to drill and tap the trans and then use short studs as needed. One of the holes is bolt that holds the starter in place and sliding it on a stud will help.

440 is spot on for the 2.7

By comparison the 1.8 is 282 with all the accessories. Mine doesnt have the power steering pump, ac compressor, some emissions bits, and a bunch of bracketry so knock off 30lbs and my engine is right around 250.

One of the big reasons I went this route vs the V6 motor. (Granted my cast aluminum intercooler is about 30lbs, my turbo is about 10, and my engine cradle is another 10...)

An aluminum LS1 is about 430

Posted by: Cracker Mar 5 2017, 08:15 PM

The flywheel, clutch, PP and adapter plate for the LS to G86/87 variants is substantial, heavy (and pretty). I didn't weigh it but would guess that it alone weighs about 55 lbs. Chris could weight his since his is still accessible. My engine only has an alternator and dry sump pump and weighs 425 lbs. A baseline comparison for power goals to engine weight - 586 hp and 553 torque - at the crank. Idles smooth, and can drive at idle with no throttle input. Very docile.

Thanks T. that LS7 is legendary. The little V6 can't compete with that monster. Chris if you get a chance can you weigh your LS3 fully dressed. Please include headers and clutch with adapter plate if possible. I've checked other sites and they say that GM's official fully dressed weight is 497 lbs but it doesn't include clutch and adapter kit or headers. Therefore, if I read T right then, I suspect that a fully dressed LS motor will weigh around 497 + 50(clutch and adapter) + 20 (headers).= 567 lbs. Does that sound about right?

Posted by: Curbandgutter Mar 6 2017, 01:29 PM

I went down South to Chip's house and he tapped in four additional studs to the Cayman transmission. You can see them in the first picture (Chip's motor and trans). He machined up a trick jig and was able to set it up and tap the trans in about five minutes. For those of you that may want to do this, these studs are not mandatory but we like our belts and suspenders around here.

OK this weekend I mated the Cayman Trans with the Audi motor. I started removing all of the excess piping and tubing that are unnecessary smile.gif smile.gif . It really started to clean that rats nest of tubing up quite a bit. I'll post pictures when done. Hoping to place motor in this weekend and then make the motor mounts. Chip will then start mocking up for the custom headers. I'd like to have the motor completely bolted up this month since I will not be able to work on the work for the first two weeks of April.

My remaining schedule should look like this:

April: Complete the new floor pan and button up all of the access holes.
May: Complete radiators with AC system.
June: Complete brakes, and fuel system.
July: Complete electrical system and start the car.
August: Complete body with steel gt flares
September: Complete custom body work
October: Paint
November: Interior.

We will see how it pans out but this is the schedule until reality hits hard.

agree.gif I'll post a before and after picture. I'm removing the activated charcoal, the pcv and the secondary air pump. Ill build a puke tank for the PCV. Andrew whats been your experience on this?

Posted by: Andyrew Mar 13 2017, 01:49 PM

SAI is emissions only and can be removed no issues.

Removing the charcoal/pcv isnt an issue you just have to have a place for the air to go, Puke tank works well, I have mine puking to atmosphere and it makes quite a mess. 034 motorsports makes a 1" billet adapter to the charcoal tank so you can route your puke system from there.


Another thing you have (2.7 vs 1.8) that I dont, is under the intake manifold you have a small bosch water pump with hoses that pumps water through the turbos / engine after engine shut off. Its common to remove that system as the hoses crack or the pumps leak.
Now my water pump ECU does something similar to that, but Im not sure if you want to retain that feature. Its something the ECU controls if the oil temp gets to a certain point.



I would start discussing all this with your tuner now. What do they need, What can you remove. Thats what I did, and they guided me to where I was.

Ask them about fueling, injectors, pressure regulator, Map sensor, MAF sensor, Boost control. Those are all things that need a serious discussion before parts bought.

Andrew thanks for your response. I'm interested in how your electric pump also doubles as a secondary pump for when the engine shuts off. I'm actually still thinking of using the Audi belt driven pump for primary and the Bosch pump as it was meant to be in its original state.

Posted by: Andyrew Mar 16 2017, 08:28 AM

My electric pump has its own controller that when the key is off and the engine is hot will run the pump and fans for a couple minutes. I can program the temp at which the system trys to stay at from 140-205deg.

Whats crazier is that that white taped up lump I am going to say is the rest of the engine harness wiring smile.gif

The biggest issue facing conversion owners is the wiring goes the wrong way, requiring us to extend the factory wiring or cut and rewire most of the engine components.


It not THAT big of a deal because most of the engine bay stuff gets resistors on it and is not used. My local tuner is building wire tuck wire harnesses for the 1.8's, I might pick one up and rewire my engine bay because I have a big loop of wires that are just unnecessary.

Probably one of the most critical areas of emphasis in race cars are the electronics. Nothing matters much about a build if it is plagued by electrical gremlins (which can lead to: failures, fires, blah, blah, blah). The difference between the quality of electrical components and emphasis on such is often under-valued...or misunderstood. In a complex car like Rudy's...I believe nothing should get more attention than the electrical system, nothing. Good luck Rudy... smilie_pokal.gif

Posted by: Curbandgutter Mar 19 2017, 10:42 AM

Tony I agree 100% the devil is going to be in the wiring with all of the sensors and actuators. Also need to make sure that there are no boost leaks. I plan on taking all the time necessary to get the wiring done right. Will lay out the entire system on a huge table and check every wire and connection. I have a close friend who is an electrical engineer and has written multiple university textbooks. Guy can make his own chips.....as in designing the circuit and actually building the chip in his garage. I think with him and the knowledgeable folks in this board I'm going to be all right.

Andrew yes that big lump is the wiring harness. I wrapped it in cellophane. I'll sure be needing your's and Mike Bellis' input when I get into it.

By the way, I'm checking out for a while on vacation.

Posted by: csdilligaf Mar 24 2017, 03:42 PM

Rudy and I discussed the header plan. At first I was going too make us both a set and go equal length and relocate the turbo's to a better location for our needs but then in the interest of speeding up the process we decided to go cheap to get it running. We were aware of the cracking issue but Hell, at $135 they are disposable. We will most likely chop and modify them at least once. So consider them mock up.

Posted by: Mike Bellis Mar 24 2017, 04:43 PM

I went through a similar issue with my 1.8T. I bought several headers/manifolds trying to find the right location for my turbo. I had a nice SS equal length header that I cut up trying to realign the turbo housing to no avail. A $79 ebay special ended up being perfect. I still have about $1,200 in exhaust manifolds collecting dust in my garage...

Posted by: csdilligaf Mar 24 2017, 06:11 PM

cheapy's will work for testing but a little more money and these ones made from 1 1/4" schedule 10 stainless pipe would be better when time to finalize things. For what they cost I can't buy the flanges, elbows and pipe and then weld them up.

Ideally I want to delete the pig tail curl they have and lower the turbo with the outlet angled up slightly to clear the axels. We'll see if that is what works on Rudy's first.

Edit: They are XSPower. With some research on XSPower turbo headers I found

"XS Power is proud to be partnering with Stainless Works"

"Stainless Works manufactures them on-site, right here in the United States"

Hahahaha. Seems to me like that car does not run. We're getting rid of the evap, the secondary air and pcv. It cleans up quite a bit. Getting it to look like that may be difficult. We will come close though. The problem that we have is that al of the wiring is along the firewall of the Audi which can hid the wiring. In our case all of our wiring is visible since it's mid engine. We will have to come up with some fancy way of hiding the wiring.

Posted by: Andyrew Mar 25 2017, 09:18 AM

For me the biggest thing was there was so much stuff to fit in the engine compartment something like this was no way a possibility. I mean the piping for the intercooler take up a considerable amount of room and you'll have two turbos to pipe to either one A/W IC or run twin side mounts.

Posted by: Curbandgutter Mar 25 2017, 12:09 PM

I agree Andrew the piping for the intercoolers will take up space. However, I have the luxury of not having a rear trunk and rear firewall. Therefore, since I am going to create a side vent into the engine compartment at each quarter panel, I will be able to fit the intercooler in such a way as to simplify the plumbing. The side vents will fold into the quarter panel rather than protrude like a scoop. They will follow the angle of the tube chassis as it tapers from the B pillar rollbar to the where it pinches at the rear suspension. I'm toying with the idea of making the vent, as it folds in, out of carbon fiber. I set the intercooler in place and it fits perfectly. The intercoolers wil be set in such a way that when the rear hood and rear fenders tilt back, the intercoolers will be exposed. See attached for a preview.

The oil pan is 1/2" above the floor and the engine sits almost level. The engine and transaxle are shoved forward as much as possible. This will give me a more balanced car in conjunction with extending the wheelbase 3". The next step is to weld the engine mount s. After that it will be floor pan and finish buttoning up all of the welds and covering up all access holes.

agree.gif Exactly. Andrew they will be used for the couple of cross bars that will go over the engine/transmission bay. That way when I need to remove the engine and trans, the y come out as a unit over the top. This car is being set up to be able to remove the engine and transaxle easily for servicing.

Posted by: Curbandgutter May 21 2017, 07:11 PM

Some more progress on the transaxle mount. It ended up being very tricky since I did not want the transaxle mounting bolts to have any tension on them. The factory was designed with tension, but since I am adding a much longer ecentricity to the new brace it will add too much tension on the factory bolts. I cam up with a way to tie them together so that there will be zero tension on the bolts. They will only see shear forces. Almost done tying the back end up.

Here is the how I'm doing the front engine mounts. After this weekend I'll be move to the front struts. I need to lower front end 3 inches. I have a solution that keeps the 996 struts and coilovers. If it works out, then the car will have 3 inches of ground clearance but with the stock suspension travel. More on that later.

Be sure to drill your hole for the nipple in the stock cast mounting piece. Thats why its not sitting flush smile.gif

Posted by: Curbandgutter May 24 2017, 10:52 AM

It's not sitting flush cause i haven't tightened the nut. It will sit flush then. You have a good eye Andrew.

Posted by: Curbandgutter May 29 2017, 11:36 AM

OK the engine is finally sitting in its custom engine and transaxle mounts. Took way longer than expected. I still have to complete welding but I have to remove the engine and transaxle for that. Next step is to work on the front struts. I need to lower the ride height 3 inches in the front.


This is the front engine mount.Attached Image

This is the way I tied the transaxle mounts to each other Attached ImageAttached Image

1/2" clearance from the floor pan on both engine and transaxle. They are on the same plane and the motor and transaxle are almost dead level. I will tie the entire bottom of the engine/transaxle bay together with one single aluminum plate across the entire engine/transxle bay opening. It will be tied to the factory suspension bolts and to the tube steel chassis. This will completely tie the opening together and take out any flex in the truss system. The load will then transfer into the floorpan thereby removing any lateral deflection in the chassis. I will also take the opportunity and blend the structural element into a diffuser.

Look at what I picked up. Attached Image

Close but not low enough. The diffuser will be about a 1/4" lower.

Posted by: Curbandgutter Jun 2 2017, 10:19 AM

Well now that I'm moving on to the front struts, I know that I need to lower the ride height 3" in the front. So I started to think how I can determine how much I can raise the strut tower up into the hood while using the 996 coil overs and thereby having a lowered car while retaining the stock ride and adjust ability. I'm shooting for 4" of clearance to the pinch weld of the longs.

Well I went to a hobby store and bought some foam that they use in flower shops. Then I cut and sandwiched the foam in between the strut tower and the hood. Then I closed the hood and I got the mold that I needed. Kind of like pressing a panini.

Here is the mold after pressing it. Attached Image Attached Image

Here is the bottom view Attached Image

Then slice at the bolt locations and get the clearance dimensions from the hood. Looks like I will be able to shove the struts up into the trunk another 2 inches. Attached Image Attached Image Attached Image

And that's how you slice it.

Now I need CSDilligaf to machine the shoulder of the lower strut to be able slide into lower strut mounting point another 1 inch. Then I'll have my 4" of clearance "unloaded".

Posted by: Curbandgutter Jun 29 2017, 05:45 PM

Tomorrow I'm going to Chips place and he is going to put the lower coilover in his lathe and cut out enough meat to lower the base of the strut 1 1/4" into the aluminum 996 upright. I'll be finishing this portion of the build this weekend and will post pictures of it sitting at the correct ride height. It will have 4" of clearance on the front and 4 1/2 on the rear without lowering from its stock position.

This is where the strut installs into the aluminum upright Attached Image

This is where we are machining the strut to be able to lower it Attached Image

This is what the center console will look like. I'll be able to
run all of my wiring and piping through here. It will be covered
in carbon fiber and will be removable for access. This will add
extra rigidity to the frame as well. Attached Image

I'll post pics once it's sitting on it's own weight. Next step will be to remove engine and suspension and finish welding everything up, add the center console. Will be ordering floor after the 4th and then install that as well.

Yes that center tunnel is going to be very effective in torsion and very useful for the shifter console support and to serve as a conduit for all hoses i.e. fuel, radiator, brake, AC and electric.

Glad to see yo back on your project. I know how it is when you hurt your shoulder. Last year in May I destroyed my right shoulder due to a fall on concrete while pulling some hoses tripping backwards. I did everything I could with that one shoulder to keep me form falling on the 996 front suspension that was on the ground. I tore all kinds of stuff on my shoulder. I had to use my left hand to move my right arm so that I could work on ACAD. I still worked on the car since all of the work was below the waist. I'm about 70% now one year later.

Kent, I will need to add two inches to the front fender and then weld the 916 fender to the expanded front fender. The rear will need to be widened 3 inches before adding the rear 916 flares.

Im picking up 19x9" front rim and 19X13' rear rim. The rolling diameter will be less than a stock 914. I've got a deal worked out on modular 3 piece forged wheels. Tires will be around $1,200.

Yep i just added the removable strut across the transaxle and will now take everything apart, put on rotisserie, replace floor, add center tunnel and finish welding the chassis as well as plugging up all of the "access" holes. Then I will do the final TWIST test. I'll be sandblasting all of the tube steel and epoxy them as well. Then install radiator, fuel tank, pedal assembly and electrical. I've got alot of work still ahead, but the major labor portion is almost out of the way.

I wish I had more rear rubber than my 10's, 13" would be very nice. run some 335's. This chassis really needs the extra mechanical grip as it doesnt have the weight to put the necessary force on the tires.

Andrew you hit the nail on the head. beerchug.gif Mechanical grip is what I'm after cause pure friction is just a function of weight. And I this car won't have that much weight to transfer.

Sorry for the long delay but I am happy to say that I've been back at it after a slight break and will have an update shortly. I've also had some time to think over some design elements and decided to remove the air scoops over the roof. I decided to stick with the hollow spoke turbo twists and I'm looking into placing the twin 996 radiators in the quarter panel. As you may know, I lengthened the wheelbase 3" and that will hopefully give me room to fit the radiators. I'm trying to not have to have radiators in the front hood.

Posted by: ChrisFoley Aug 25 2018, 03:45 PM

I went thru all my pics. Most of the work is undocumented.
The process started with cutting off some crappy custom flares that had really thick bondo to make them smooth.
Then I carefully butt welded the AA GT flares in place and hammered the weld seams smooth.
Next I chose a cut line just inside the curved edge. The location was chosen so I could shrink the edge of the removed piece to match the new shape.
Then, using a modified palm nailer, I hammered the shit out of the part left on the car to raise up the top so the wheel opening would end up at the same height as on the stock flare, and I smoothed all the surfaces with hammer and dolly.
The front and rear edges were curved outward to create a smooth shape that would line up with the reworked edge of the removed piece.
After many hours of reshaping the loose edge I was satisfied with the transition and clecoed the loose section in place with some small pieces of sheet metal to bridge the gap.
This is the point where I started taking pictures.

Well I started to install the flares. I started with it upside down cause it makes it so much easier. I painted both mating surfaces with weld-thru-primer before welding. Notice the rear fender how it encroaches onto the rear tail light. That is because I stretched the wheel base 3". I like the way it is fitting. I will need to add about 6" to the rear flare and 5" to the front flare. I'm waiting for the new rims to come it before I do that though.

Andy I hear you on that. The reason it's 6" is that the 996 hub to hub dimension is 5" wider than a 914. So, add to that the 335 tire on 12.5" rims and there are the ingredients for the wide rear. I think that it wont look too weird since I am adding an 18" wide radiator on each side within the quarter panel that will be taper to the interior about 12" from the face of the quarter panel. If I did not have that I would of put in some serious + offset on the 3-piece rim and tuck the meats inside. But I don't like the look of the meats tucked in. Yes there will be more aerodynamic drag on them....but I don't care, it will look downright mean.

Well I'm in the process of welding the fenders on. It takes me about 4 hours per fender. Here is how I did it.

First, flatten out the bottom lip of the existing fender. This is to give you a flat area with which to attach the new fender. At this time also cut the existing fender along the bottom edge.

Attached Image

Then attach the fender to the two bottom lips and weld. Then tack weld along the top center of the fender. This will give you 3 points where it is attached to the car now.

Attached Image

Then cut from the bottom to the top half of the fender an attach panel clamps. I found that using a thin cut off wheel worked the best. It gave a nice gap to weld and was not so tight that it would bind the panel clamps when trying to pull out.

Spot weld in between the clamps

Then remove and spot weld remaining gaps that the clamps left behind.

Cut and clamp the other half

Weld, remove clamps, weld, and grind. I find that it was super easy to grind with the cut-off wheel and then to finish with an 80 grit disk sander.

I dropped off my bumpers to Oscar and had breakfast w/ Rudy and him yesterday. I felt like I was in the presence of Royalty as I sat with these 2 metal-meister's. Afterwards I stopped by Rudy's to check his progress and snapped a couple of pic's. Very impressive build.Rudy took the time to walk me thru the flare install. He said it was easy peasy but me thinks it's a trap. av-943.gif Seriously, he made it look simple but I know better. biggrin.gif Anyway, here are a couple of shots of Rudy's project.

Hey Guys , @http://www.914world.com/bbs2/index.php?showuser=16669 @http://www.914world.com/bbs2/index.php?showuser=19241 @http://www.914world.com/bbs2/index.php?showuser=172 @http://www.914world.com/bbs2/index.php?showuser=2755 @http://www.914world.com/bbs2/index.php?showuser=2388 @http://www.914world.com/bbs2/index.php?showuser=9964 thank you for the compliments they really do help with morale.....encouragement helps fuel the project.

Those butt clamps were amazing, and cutting it with the thin 1/32" cut -off while using the fender as the scribe line was the trick. Also doing one half of the fender at one time was very helpful. I used 0.23 welding wire and a 110-volt Lincoln. It worked perfectly! My 200 amp wire welder was too big and it didn't like to push 0.023 wire 15' in the gun. I didn't want to tig cause I'm not good with Tig.

Well I completed the 3 fenders and the last fender is all tacked in. It now needs final welding and grinding. It will take about 30 minutes to complete. Then it's off to the floor and finish the openings in the chassis.

As for the cut-off wheel I didn't know it, but I stumbled onto some super good wheels. I was cutting along no problems and then ran out and got another brand since my local welding store ran out of the ones I was using. So I bought this other set which was expensive and was surprisingly, "made in the USA", but was pure crap. It lasted 12" of cutting into the fender before wasting away. You could watch it reduce in size in real time......ridiculous. And then, dust everywhere. The original ones would last about 12'....feet not inches. So the EXCELLENT cut off was by Pearl and it was a 1/32" thick wheel. It lasts for one fender if you include grinding. However, I think that if I did not grind with it that it could cut all four fenders.....it's that good.

Here is the Excellent wheel that I used.

Update pictures of center tunnel and floor. Ill be finished with the center tunnel this weekend and will start with new floor. I decided on making my own floor so we will see how it turns out. I still need to add the web struts at each end of the center tunnel and it will be complete and fully structural. I plan on doing twist test soon and will be testing it with an without the top bar that tie both the rear roll bar hoop and the front roll bar hoop. If the twist test shows 1 or 2% stiffness improvement....then they will be removed.

Hey Tony... I sure hope it will come in less than 3K #. I do believe that it will be slightly heavier than a stock 914-6. I'm counting on some composites on the body to help offset the weight.

All right now....I finished with the center tunnel. ADDED WEIGHT TRIGGER ALERT Never mind that it is accounted for and offset with carbon fiber. Next step is the floor. I am getting the Eastwood 28 inch hand beader. Hovwever, I have a motor that I am going to adapt. Then I am am going to add so much beading that it will make us all sick and I'll have to scrap it and do a more "normal" look. Also, I've decided on using inboard suspension on the rear and on the mac pherson strut front suspension. I want the ability to make the shocks to travel more than the wheel and I want the ability to create a rising rate motion with a linear spring. Any input on that is appreciated.

Not sure what you're plans are for plumbing but a heads up on a lesson learned from my console:
If you're planning to run hard lines, make sure you have a way to get them in/out of the chassis, once the console is in place.
I'm likely going to have to slice up my console so they can be installed and/or removed/replaced for any reason.

Chris, did you run hard lines down the center, and if you did is there any thermal advantage over the hose option? Mine are run down the center as well and fishing them out is pretty straightforward.... I try to expect repairs like that so I've isolated my hoses and fuel lines so if there were any leaks, they just pour out of either end and not in the passenger compartment. I'd think hoses would be a better thermal isolator over a hard line even though they're not as pretty.... and your work is really good looking!

Quick update, I finally finished welding the tube frame. My son is designing new lower 996 control arms to extend the front track 1" on each side for a total of 2". The control arm is getting a revised location for a strut to install inboard coilovers on the the mac pherson strut design. The mac pherson strut will be replaced with a sliding shaft and a monoball on a camber/caster plate. I think that this may be a first, not sure, but I haven't seen it on the web. While that is being machined by CSDILLIGAD out of a solid piece of 2026 aluminum on his HASS CNC mill, I will finish bead rolling a new floor. The 3-piece forged modular wheels were supposed to come in this week, keeping my fingers crossed maybe this week. BTW, I decided to convert the rear coilovers to inboard coil overs as well.

Question for the group, does anyone know the specs on the front ball joint for the 996 control arm? I need to source them for the new control arms. Any help would be appreciated. I'm looking for the length and taper and diamters. I'm hoping to find an off the shelf ball joint that I can press into the new control arm.

I would check with Elephant Racing for the ball joint and look at their selection of 996 arms and components.

If I'm picturing correctly what you are talking about, I remember seeing this on an SCCA tube frame 914 a bunch of years ago - Doug Arnao's car that he ran in GT2. It was one of the iterations of his car. If I recall correctly, he initially built a dual A arm setup for the front suspension but the tech inspectors disallowed it. He wound up running the upper A arm in a fixed position and using a modified 911 strut as an upright. It had a fixed shaft that slid through a spherical bearing or rod end in the fixed upper A arm. And I believe it must have used an external shock absorber (i.e. not part of the strut). It was an interesting way to approach it.

I haven't read through the whole thread, but this is a cool project. I'll have to read more of the thread!

I like that idea. Are you going that route to try to improve motion ratio? How are you planning on making the sliding shaft? Gutted strut damper?

Yes the reason is for the motion ratio since I want to be able to cause a rising compression and I also want the shock to move more than a 1/2". With this setup, the shock will have a full range of movement as opposed to a very limited range. My hope is that this lowered car will not rattle your contact lenses off. In order to tune that, I’m using a shock that is 4 way adjustable. It will be able to be tuned to absorb the freeway ripples effortlessly but then stiffen up in steady state motion. Both compression and rebound will be adjustable for steady state and for rapid motion, hence the 4-way adjustment. As for the sliding shaft, I will look at both gutting the strut damper and also making my own sliding shaft to keep the unsprung weight down. I may make the portion of the shaft that does not move to tie into the camber plate and then put the receiving shaft with bearings onto the unsprung portion of the assembly. I can also move the sway bars up and parallel with the coilovers. This will make adjustments in ride height and sway bar tension very easy.

Posted by: Curbandgutter Dec 12 2018, 12:16 PM

Thanks guys.

Andrew I based my offsets on hitting target track widths and was not concerned with tucking the rears in. The front and rear track are now square at 63". The interesting thing with respect to the rear offset is that it's a 0" offset so there will be less eccentricity on the rear wheel bearings. The car will be wide that's for sure. I measures 76 1/2" to the rear rim edges. I figured if I was going through all of the trouble with tube chassis and all, that I was not interested in making a meek rendition of the 914. I'm hoping that with the extra width and the 3" wheel base extension that it will look like a panther crouching and ready to pounce.

Obviously I need to extend the fenders but I want to keep the curve in them rather than a straight extension. I have a couple of ideas to do that.

Kent don't know about the Curandero Come on by and check the wheels out in in person. They are 3-piece forged rims with custom offsets. I really like the look.

Rudy,


Your essentially going to need to extend the fenders 5", The rear of the fender is where all that dimension is going to look the most odd.

I know you've worked with foam before, possibly a good idea to lay it out in foam and shape it a bit before you start cutting? Maybe do a wire frame of your potential wheel arch location and after putting some foil on your fenders to protect the steel spray some expanding foam on them in multiple layers and start forming it out?


Thats what I did for my V1 dash and it worked out really well. I had issues where I was trying to spray to much in one location and the foam never setting but in general a couple layers made the job easy and I was able to cheaply and easily template out what I want.

You could do this then make cardboard slices for what your fender line is and then be able to transfer those new measurements to the formation of steel?


Fun stuff ahead smile.gif This will be really fun to watch! Wish I was closer sad.gif

Thanks for the suggestions, I've never had to extend steel fenders like this, but I have some ideas. The end product is to continue the vanishing edge instead of just extending it straight out like an extrusion.

I stretched these flares pretty far. Since yours are already on you will likely need to use another method.

Posted by: Curbandgutter Dec 13 2018, 01:10 PM

Oh I see, you extended them from the quarter panel. They looked good after you finished "massaging" them into shape.

Posted by: Curbandgutter Dec 13 2018, 01:21 PM

Here is a shot from the rear:

Front Rim:

This is how much I'm needing to extend front fender + 1 1/2" since the lower control arm is being pushed out to give me the 63" square track.:

Don't understand what you mean by this. Who or what are the Blinky episodes? Can you put a link in?

Thanks! The Binky flares are fiberglass and I don't think much of that will transfer to making steel flares. Thanks though!

Close but not what I’m going to do. I want to keep the vanishing edge so when you see the fender from the side profile the current flat vertical area will shrink. The fenders will look more curved. Do you know if that car is from one of the world guys?

Posted by: sixnotfour Dec 13 2018, 03:08 PM

ya its boxy ,,, It was , has been sold , I dont know where it got of to..

Posted by: Curbandgutter Dec 13 2018, 04:36 PM

This is what I'm thinking of:

Seems like the "flat" portion will be reduced by about 2 1/2":

Posted by: Andyrew Dec 13 2018, 05:53 PM

I think that will work, just afraid of the rear section getting so tight.

That's why I was thinking you might need to foam it out to be able to try out a few options before you start cutting and welding.

Unless you absolutely have the design in your head your going with.


Another pic for idea refference. A more rounded fender.you can see the front fender is slightly flatter.

Posted by: Curbandgutter Dec 13 2018, 06:55 PM

Thanks, Andrew for your comments and suggestions. I'm thinking that the final product will be like yours but edgier. I still want the flat design elements that are found throughout the 914. So it will look like yours but with a vertical flat element as found in the 916 flares.

Posted by: Cracker Dec 13 2018, 07:33 PM

Keep in mind, where "wide flared teeners" usually have issues is between 10/2 in the top center; and on the inner chassis if you run a reasonable amount of camber. Keep up the good work...remember, it doesn't have to be nicer than Chris's! biggrin.gif

PS: I know you are already aware of ALL of this but get the tires on there - with how large they will be it will indeed have to be "boxy' to carry the edge.

Good things to remember. However, I have the 996 track which pushes the wheels out. I have plenty of room on the inside wheel wells. With respect to the boxy look, I don’t want to completely remove that or it will look like a 914 with 911 fenders. I still want some of the 914 flat edges. And absolutely, I wouldn’t attempt cutting fenders without tires......... and with regard to Chris YES IT DOES YES IT DOES, YES IT DOES hissyfit.gif hissyfit.gif evilgrin.gif

Posted by: djway Dec 14 2018, 02:34 AM

I am sure you already know this but just in case, fully compress the suspension with tires on when hanging the fenders to make sure that the tires do not rub when bottomed out

Posted by: Curbandgutter Sep 3 2019, 03:06 PM

Hey guys, a little update. The project is still ongoing.....but I've been slowed down due to.......(insert typical excuses here). But really though, I completed the frame and am now working on the floor. I am waiting for a bead roller and English wheel that I ordered. The bead roller is a Mitler Bros with Covell forming dies and a host of other dies that I will use to make floor and to make the pieces that I will need to shape the "wider" fenders. The English wheel is a Metal Ace. I've also ordered a Roper Whitney 48" box break. Once all of that comes in I will be able to complete the floor. I'm also moving into a 50' x 24' shop. Up to this point I have been working outdoors so I really can't do much when it's too hot or weld when it's windy or work when it gets dark. Now I will be able to work whenever I feel like it so I'm expecting to get way more done. Also, there this month I find out if we sell our property of stay in it. If we sell, then I'm building a new house and then you know that this project will stall. If we don't sell then there won't be a stall. Also, I figured out a way to widen the front track of the 996 suspension without having to machine new control arms......stay tuned since it's very cool way that keeps all of the suspension geometry and can use factory parts.

@http://www.914world.com/bbs2/index.php?showuser=1659 Yes sir you can. That's why I used those removable welded adapters. It's a tight fit but the engine and transaxle come out of the top. It's kind of unique for a 914.

I've started building the floor pan Attached Image

but I first needed to add the supports for the 914 seats Attached Image

and for the Tilton pedal assembly. Attached Image

I was able to shift the seats 1-1/2" closer to the center of the car and the pedal assembly 3" further away from the center of the car. As you can see the brake pedal almost aligns with the steering wheel centerline Attached Image

By doing this I was able to more closely align the seats and the pedals with the steering wheel centerline. In doing this I found out that I am in need of the seat elevation control tab that attached to the floor pan.

If anybody is cutting one up let me know as I need this part. Attached Image

ALSO THANKS EVERYONE FOR THE WELCOME BACK......ITS NICE TO BE BACK!!

The body work remaining is

1) make a front trunk
2) tie in rear trunk
3) finish interior long cover
4) make interior tunnel cover
5) flare out front and rear fenders and additional 5 or 6 inches.

suspension work remaining is

6) my son is currently designing and machining the front control arms to include a 3" front track widening and connections to remove strut and transfer to inboard coil overs.

I'm feeling like doing 2,3,4 and 5 first while son does 6. Will leave 1 once I figure out how to vent this thing out. I want to try something different.

Using Langmuir Pro Plasa Cutter to cut sheet metal. I fabricated everything on the table that is painted red. Had to modify the table to my likingAttached Image

So I cut out the long covers and a bunch of ac/vent holes that I'm closing up.
I closed every single opening along the firewallAttached Image Attached Image

I put an offset in the stationary cover so that the removable cover fits close to flush Attached Image

Adding rivnuts to make it all removable Attached Image Attached Image Attached Image

This is what it will look like when open Attached Image

A plasma table, bead roller and mag brake? Where have I seen that set up before? happy11.gif
Rudy - You're killing it! I love the removable long panels. Very cool design that you brought to life. Great work! aktion035.gif

"This is whats coming next"

Holy wheels batman! Just Damn!

Going for the record tire on a street 914??

Thanks guys, Happy New Year back @ValcoOscar ,

@76-914 see you this weekend.........no more covid. I will have my new AC system by then. I'm going with a RESTOMOD unit Attached Image

@horizontally-opposed thanks man....I can't wait either.

@tygaboy happy11.gif I don't know...........where? CNC mill and lathe are on backorder santa_smiley.gif Bought a Precision Matthews 940 mill with Acorn CNC controls, and a Precision Matthews 16x40 lathe. Got something planned for the mill since it has the ability to do 3d contour mapping. Got a little dirty trick planned up my sleeve. You're going to love it.

@Andyrew happy11.gif I don't know if its the record but it will have a 63.5" front track and a 63.0 rear track. Attached Image

I'm going to flare out the fenders next. Fronts are +4 and rears are +5 over and above what the 916 flare is. Attached Image Attached Image

I'm building a jig to keep the fenders in exact location so that when I expand them, they will keep the exact location as the 916 but just wider. I will also extend the curvature transversely along the rear hood. In order to do this I will have to make the face of the fender shrink by about an inch. Can't wait to see it sitting with the new meats and the lengthened wheelbase.

Ohhhhh and pretty soon I will do a twist test to see if I got this thing much stiffer than stock. smile.gif

Wow !
That’s looking “rude” can’t wait to see it!
Hope everything’s going great.

One of my fave build threads hadn’t seen it awhile . Just finished a morning coffee in downunder oz and got up to speeeed

I just returned from Rudy's and all I can say is be prepared to be awe stricken. IA very humbling experience I must say. I'm not even sure that the trunk lid will remain stock. The welds are impressive as well. Such small, flat "dimes" on thin metal I thought they were TIG welds but they are MIG. Some upcoming metal work will be quiet involved with compound curvatures but I'll stop there and let Rudy reveal when it's time. beerchug.gif

That looks awesome. Can't wait to see the finished product

This is beautiful work.... but I have a question.

Looking at this picture:

IPB Image

I noticed the diagnoal bars on the bottom of the engine compartment. My question is: How are you going to get the engine in the chassis? The inside diagonal bars are in the way of lifting the engine up in to the engine compartment.

The engine drops in from the top. The braces on top are removable, clay.

@http://www.914world.com/bbs2/index.php?showuser=9964 lol-2.gif lol-2.gif lol-2.gif Thanks man.......but you're over selling it.........makes it harder to impress. shades.gif All kidding aside, thanks for the compliment.

I'm moving on to flaring the fenders and making room for intercoolers in the quarter panels. Planning on cutting the 1/4 panel and bending approximately 30 degrees. After I'm done with it, you'll be able to carry luggage in there. aktion035.gif aktion035.gif aktion035.gif It's not going to be a make-believe-vent shades.gif .

A little look into what the ac system is going to be like

This is a RESTOMOD unit. Attached ImageAttached Image

I will be adding aluminum diamond plate in the footwell area. This is my variation of AUTOCardboard.....sometimes I use foamboard.Attached Image

This thing is super cool. (Sorry, couldn't help myself.)

Do you think it might fit into the stock area in a 914 with a standard fuel tank if the expansion tank and factory fresh air box are removed? Does it get under the cowling?

Posted by: Curbandgutter Jan 14 2021, 07:16 PM

I think it would work. Even if you have to cut the floor of the firewall to lower it say an inch it will fit any 914. Also, it beats anything out there with all the electronics. It's an amazing unit with electric servos. No wires to control air mix. This is infinitely variable mix too. They have the best billet air vents as well. Installed in this fashion it will leave all kinds of legroom. It's the way to go IMHO.

I'm thinking of using this style of vent Attached Image

Simple answer is no, mocked one up a while ago. But if you don't mind a bit of cutting on the separator panel then yes it will fit, have to move the cowl support or build a new one, and it gets in there just fine. Added benefit is the floor heat venting actually works, for pure A/C it does not matter that much. And the wiper mechanism is out of the way if your worried. Lots of room there just not a lot of depth, you have to pull it over to the passenger side as you have steering shaft going into that area also. One thing I was messing with was moving the blower off the unit to gain a bit more in the packaging space. Can't remember if you lost the washer bottle or not, not a big deal, plenty of Modern VAG cars have remote washer bottles with electric pumps that would fit under the gas tank and keep the fill high. All about packaging.

This build it will not be an issue at all.

Keep rocking this one aktion035.gif
