Project MBT-8 914 (warning - big pics for dial-up), new build thread for my V8 tube car Options

[byndbad914]

Took it drag racing a couple weeks ago to opening weekend at Bandimere. Fun shot cuz the car is SO tiny compared to typical vehicles. I am behind the Honda on an uphill slope and the car is still small looking (IMG:style_emoticons/default/smile.gif) Perty cool IMO.

[byndbad914]

you can see in the pics above I haven't buffed out the driver's door since I just did it a couple weeks ago. Letting the paint have plenty of time to cure.

and a sample of the camo green to black color contrast I expect.

How did it do in the quarter mile? I'd think it should be capable of high 10's, but that's probably stretching it at your altitude.

[byndbad914]

wow, good call Steve.

It was horrible times due to numerous things, like no weight transfer and lack of traction period, but I ran a 12.88 at 113mph, 13.4 at 113mph , and a 12.90 a 114.7 mph which was the run the clutch smell became very obvious (IMG:style_emoticons/default/sad.gif)

An AWD 997TT ran right behind me - 11.97 at 113mph! And that time really matches the mph, so I think my car is good for 118mph with a new clutch. That would be around 11.6 equivalent at a mile high and 10.8 equiv or so at sea level.



I have suspected my clutch has been slipping for a while now, but that really confirmed it. I think it is because I draw so long on one gear (2nd) from 60mph to 100mph, then third is 100 to 140mph, so the mechanical advantage in the gear isn't there and it must really work the clutch.

So I need to go to a Kevlar disk apparently. Explains the mph drop I have been noticing after the front stretch at Pueblo (the front stretch is a 1/4 mile track BTW and I started out hitting 135mph and have been as low as only hitting 125 or so last track day.

edit - talk about your size comparisons (IMG:style_emoticons/default/smile.gif) Look how big that turbo is!

[Andyrew]

That is extremely suprizing, I would expect your MPH to be much faster!

[byndbad914]

keep in mind this is at a mile high, not sea level. I hit the scale on the way back after the first run and was 2800lbs exactly with me in the car, and probably 420 peak HP at this altitude and the fact the car is not light by 914 standards all add up.

Take the car to sea level and the peak 525HP comes back and the mph would match something in the 120s for sure.

So, running an 11.97 at 2800lbs equates to 323 whp. But keep in mind, I make more peak whp and that is where people make mistakes in their calcs - they put the peak whp they measured at a chassis dyno in the calc and think they will go 130mph.

The calc is AVERAGE whp during the run, and I can believe over the quarter my average HP at altitude is roughly 323. Really after thinking about it I expect the car to run more like 116mph based on a bunch of math assumptions of course which would be 340 whp average.

assuming 20% increase to sea level of 408 whp average, then I would run 124mph around 11.07 if the car hooked, etc. Now, go back to the original tub setup, no cage etc and it was 2305lbs + 205-ish for me clothed and jacketed and the ET drops to 10.38! But that is a VERY UNSAFE car so I carry ~300lbs of "save my ass" with the new tube chassis car.

(IMG:style_emoticons/default/av-943.gif) That's insane! I wanna ride! That is faster than my Blown '72 Nova ran at our altitude! Sounds like a fun one! ..and a little (IMG:style_emoticons/default/screwy.gif)

[So.Cal.914]

talk about your size comparisons Look how big that turbo is!

Compaired to your car it looks like the turbo should have dolphins leaping in front of its Bow.

I had followed your build with great anticipation. Nice to see her get the final

touches. When I did that work for you on the paint I am ashamed to say I did not

realize it was the same car. What can I say...All the good stuff is hidden under

sheet metal and composite's. (IMG:style_emoticons/default/smile.gif)

[byndbad914]

hahaha, yep Paul, that was the intent actually. I wanted to look like a simple 914 with a body kit and bolt-ons. It is fun to see folks walk up, realize it has a Chevy and start making comments... then they stutter and the eyes widen when they look passed that and realize the whole car is a tube chassis with a skin of a 914. I get a lot of comments on having kept the stock dash and steering column for instance because it makes it easy to overlook the fact the floor of the car isn't really much of a floor (IMG:style_emoticons/default/smile.gif) I intended to run stock doors with door panels to keep the eyes away from the tube floor, but it just isn't worth the extra weight in the long run.

If you know much about G-machines or the coolest Camaro ever, Gottlieb's Big Red Camaro, I fell in love with that car as a senior in HS and always wanted to build a tube chassis, big HP road race car that really doesn't look like much more than a modded stocker at first. Big Red started a whole phenomenon single handedly.

Funny, not sure if I ever really mentioned the inspiration for my car... funnier that it was a Camaro and not some sort of Euro race car.

Sleepin' - post a pic of the Nova if you have it! I love those early 70s Novas. You're right about the altitude and what it takes to run well. My friend had a twin turbo (junkyard turbos of old Tbirds) 377 stroked Windsor I build in his 91 Mustang LX that would run high 11s and at that time (mid 90s) that was a fast ass car at Bandimere that he drove to and from the track in. Now with the turbo technology and all the AWD cars these days, it was amazing what some cars would run. Then you would see a hopped up muscle car on slicks run in the 12s at best.

Wasn't much to look at in primer. The engine was a perfectly setup from (what I gather) an "old school" builder 355 and fun as hell in it's own right. I put the mini blower and had the heads redone with 2.02/1.60's...with the flat top pistons it became pretty fun to drive, but almost worthless for any tires I could fit under it. I just did not want to be the one to (IMG:style_emoticons/default/sawzall-smiley.gif) the trunk on such a solid car. I sold it in November (to buy the 75 914) to a friend of a friend in South Dakota and I hear it is hitting low 11's at that altitude.

I miss it, but not as much as I miss being able to run on the interstate at 85mph and still getting 20++ mpg (4:11's suck on the Interstate), and being able to go around corners. (IMG:style_emoticons/default/biggrin.gif) (IMG:style_emoticons/default/biggrin.gif)

[byndbad914]

primer is clearly fine by my standards (IMG:style_emoticons/default/laugh.gif)

My 70 Mustang fastback I sold to pay for college (the better investment but I MISS that car on a regular basis) had a 302 I built up that would run 13.70s spinning most of the track on BFGs at 104mph hahahaha. Same story too... drive it home screaming along at 65mph with 4.11s! And handling in that car was whether you could stomach a 4 wheel drift thru a bend in the road.

But man oh man the memories with that car. I don't have any pix scanned to post but it was orange with black trim and big arse tires (265/50/15s on the front with rolled fenders and they still rubbed) and 295/50/15s stuck on the rear with air shocks to get a little extra clearance (IMG:style_emoticons/default/biggrin.gif) Old school deep dish slot wheels I bought for $200 out of the Recycler and so forth - good times.

[Sleepin]

Yeah, I drove it from Brighton to Grand Junction with 4:11's! . . .5 1/2 hrs.... slowly! (IMG:style_emoticons/default/biggrin.gif) Gotta Love the rumble of a nice V8 too!

I think at this point I am leaning towards the WRX engine in my 1.8. I miss playing with turbo's

I bet you kick yourself for selling that '70 302! I have a few cars that I lie awake at night and wonder what happened to them....and what I was thinking when selling them.

I will have to swing up to Bandi one of these days you are going to be up there! I'd love to see it in person!

[byndbad914]

I miss the car, but don't kick myself for getting my BSME with the money. That said, I will own a 70 fastback again someday. At some point I will certainly sell this car an move on (I always do).

Why not go with the bigger scooby 4? I think I have heard of those 2.5L with a bit of extra boost clearing 300HP. Or, cooler, would be to put the boxer 6 in the car and single turbo that up to around 400HP.

I like those scooby conversions - it is a "natural" progression to more modern boxer technology IMO. When the Baja Shop was doing my car I noticed nearly every new sand rail they built was a turbo'd Suby, not a VW.

But the rumble of the V8 can't be beat. At altitude tho' I am already starting to think single turbo on my car (IMG:style_emoticons/default/happy11.gif) and broader lobe center cam. Won't happen but fun to talk about nonetheless.

I will post if I am heading out to Bandimere again in the future if I get notice... the Volvo wagon next to me in line is my buddy and he basically told me on Wed of that week he might go to Bandimere on Sat, then after the car wasn't together in time ended up texting me at 2AM Sunday morning to confirm we would leave for the track at 8AM (IMG:style_emoticons/default/blink.gif) so that is the notice I am used to having to work with hahahaha.

[Sleepin]

Oh believe me, I have thought about the bigger motors! (I would like to have seen my Nova engine in a 914!) I think the most economical rout would have to be the 2.5 out of a Forester or Legacy. Fine to have stock for a year, save up some cash...then get the turbo. ahh one of these days (IMG:style_emoticons/default/biggrin.gif)

[turbo914v8]

I simply love looking at your 914. Thanks for posting more great pic's (IMG:style_emoticons/default/piratenanner.gif)

[Gint]

The Camaro kid across the street and his Firebird buddy came home a couple of weeks ago from Bandimere telling me of the "car like yours with a V8." I'm guessing that was you Tim.

how funny. I am guessing had to be as I was the only 914 out there (IMG:style_emoticons/default/smile.gif)

turbo - I am finally getting to where I like how it looks too. The pic at the top of the page I think is a great angle and with the flares it looks pretty slick. I need to figure out a way to get air in the car efficiently without having that monster air cleaner screwing up the lines of the car...

hello

what is the model of seats
