Chappy, you might want to check out GHL headers with heat. I bought them direct (they are in arizona)...great guys to work with and a really excellent finished product. They have 1 3/4 and 1 5/8 diameter systems. Mine isn't installed yet (trying to get motivated to start the 3.2l install)....here is a pic:

To answer your question about the Yamabond/threebond... best way is either with a razor blade in the solvent tank (careful not to gouge those critical surfaces!) or by taking it to the machinist when they align-bore it and true the mating surfaces.
Of course, the idea of rebuilding and blueprinting an engine, then using the sealants mentioned, is that it should not have to come back apart any time soon.
At the shop i worked at, we had a real problem... We'd do an engine rebuild -- they ran so good and never leaked, we'd never see the owner nor car except for oil changes and regular maintenance.

Thanks for the response.
But I still don't understand how those techniques will help me get my glued-together case back apart when it's time

Sure - I get that. I hope it's true, especially for a 911 bottom end. OTOH - I'm building a 2,8RSR clone, possibly in stages (first with some overbored cylinders, later with Nickies) which should still not involve disturbing the bottom end, but the reality is that's real close to the limit for a mag case and I'm expecting to freshen mains more frequently than a just-street engine.

Sunday, Paul aka (Lotus-65) was over and we attempted to shoot a video of my car running through the gears, I made up a camera hat so the camera was mounted on the bill of my cap, this was so i could look at the gauges to analyze the A/R's and boost on replay and Paul had a hand held video cam to catch the ride.
All i can say is we are both idiots, in my attempts to start my hat cam, i kept turning it off instead of on and Paul shot the entire time in the infrared mode. so we have nothing to show you....
I will try again......

Side note- while my turbo 914 is not as perfect or brutal as yours, as an auto cross weapon its doing just fine. In yesterdays event I finished 3rd. Overall. Out of 106 drivers. The cars that beat me came and went in trailers, each had over 300 hp, and 2x the tire.
If you ever want to make a point of how fast a 914 really is, I'd be happy to drive yours at an auto cross...

All the anxiety i had to go through and the risk of going over 120 twice on the highway at 1PM is hurting my odds of getting away with it.
My last run i had a Carrera S come up on my rear and i slowed down to about 20 on the entrance ramp and waited for the traffic to pass to give us an open shot. When i glanced back he was a very tiny car in the rear view mirror. He exited when i did but turned the opposite way.

I got out and did another video today with my dog Darla, this one is better, i figured out how to turn it on....
http://homepage.mac.com/davidchapman1/Twit...eTheater25.htmlThe clutch did not hold well today, on one run that i didn't video it slipped 5th real bad and i pulled some higher RPM's than i was comfortable with and got kinda scared.
This is the first time i have been able to analyze the A/R's and the Boost (hat cam worked), the top pillar gauge is my A/R and the bottom one the Boost the shift light is set at 6000 and i usually shift it around 6400, Boost looked good came up to around 14lbs
at the highest threshold, the A/R/s are all over the place. On WOT the mixture goes way rich down to 10 and the engine lags abit, then moves up to around 12 where it should be but i can see it climbed up towards 13 which is getting a bit leaner than i want, a flat 12 on boost would be optimal.
I can see the gauges great on my video capture because it is full screen and uncompressed.
I wish we had captured that run with Paul the other day in the infrared Twit video because the clutch held pretty good but what you can see, is how fast i run out of gears, i see the end of 5th so fast that i am always digging for an extra gear. It's hard to just let off of the gas when your out of gear and at redline. The good thing is that it limits me to a reasonable but insane speed. I really dont want to go 180 in this thing.
Two things i need to do:
A- Send my WUR out to Brian Leask and have him pre adjust it and make adjustable to my engine mods to help even out the A/R's.
http://members.cox.net/930wur/B - Or get the new digital WUR for a few more $ and tune it with the laptop.

Maybe at BIR or a standing mile event...but on the street 180 is insane...I agree. With a 930 box you will be able to get that. Hell, you need a stronger box & clutch for that beast anyways...and best of all, you won't waste as much time shifting. As far as driving fast on the street...be careful. I know you realize that I would never exceed 120 MPH on the hwy.
Glad you're having fun with your car. Feels good to be driving it instead of building it...huh?

Sep 30 2008, 10:53 PM
Do i need it to go more than 120? I dont plan on racing the thing, i imagine it goes close to 140, i haven't peeked at the speedo. i will have to set up the lap cam for that or teach Darla to film it, I am sure she could do as well as Paul and I.
As you can see i pick my spots, the one in the video is a free lane that runs right up to that exit. I dont want to get in the habit of doing this, but for the time being until i
get everything sorted out i may have to make a few short lived hammer down runs.
Even with the boost down to 10 the car is still plenty fast, just not as fast......

Chappy, I know you to be a responsible cool mannered guy. You no doubt pick the right time & place for such shenanigan's. That said, I'm not worried for you or the public...because you possess the proper judgment necessary to pick and choose the right place & time. And besides...cars like yours and mine accelerate so hard that a run up to 120 is something that literally takes around 10-12 seconds from a dead stop. From 70 mph, it takes about 5 seconds or so to hammer your car up to 120. Assuming you are doing this on a quiet stretch of 2AM freeway or a back country road, the only real threat I can see is a big fat ticket. When I drive my car I fantasize that the roads are all shut down like the Silverstate Classic so I can drive as fast as I want (and my car will go north of 180 MPH) but we all know this isn't possible and I find myself driving close to the speed limit 98% of the time. It's that 2% that could get me into some trouble...know what I mean?

Oct 13 2008, 08:56 PM
Yep, the 901 is still turning the wheels...
The clutch really slips running the boost at 14lbs, I will need a heavier pressure plate
if i want to run the boost 12lbs or over.
I hope to get into a stronger box next Spring.
byndbad914
Oct 14 2008, 01:24 AM
I wouldn't even bother with trying to get a better PP frankly... I will go back and see if you have upgraded to a clutch master and slave hyd setup, but I had a KEP hi-perf PP in my 901 a long time ago and I couldn't keep a clutch cable in one piece for any real length of time. I think I broke 3 in one year.
And the disk diam is so small it isn't going to hold 320 ft-lbs (a guess on 187 cubes at about 1 atm of boost) and 380 HP very well... it takes a lot of spring force in that PP to make that stick and it is better to just upgrade to a better trans and a larger clutch. I know V8 guys use those transaxles up to 350 ft-lbs (supposedly tho' I have see them broken by that level) and the big KEP PP but many of those cars blow off the radials easily and don't slip the KEP clutch because of that... but put some slicks or sticky tires and get it to hook up and the clutch will slip.
Just focus on getting a better transaxle for your setup and save the money on a beefy PP and turn the boost back over the next few months until you can upgrade, no reason to waste money on a PP you won't want in a few months IMO.
The stock geared 930 would work well with your 930-ish setup. The limit isn't whether you want to go 120, 140 or 180 but what rpm you want to be turning at 75mph on the interstate - the high gear may be good for 160 mph at your max rpm but irrelevant to fwy cruising. If you think of gearing for 120 or 140 even you will be turning big rpm at fwy speed.
edit - "Kennedy stage 2 clutch and pressure plate with starter ring" - you already have this one?! Not much more you can do to keep the clutch from slipping.
iamchappy
Oct 14 2008, 02:48 PM
The beauty of the turbo is i can dial it back as i did today to 10.5lbs. the clutch will hold and i probably am still transmitting over 300 hp.

Temps are decreasing around here and it will be time soon to put the HE's back on.
This will be a good time to drop the engine adjust the valves, retorque the headstuds and see if i can shore up the area it has been leaking oil.
I will inspect the clutch for glazing from it's slipping, and may opt for the stage 3 pressure plate for the time being. I hope to still drive my car until it snows, the Dot R tires are off and the all season ContiExtremeContacts on.
I had a chance to shoot some pictures of the car rolled out on the lawn last month and posted them here.

I finally got the car back together since i tore it apart last Fall. The engine builder
would not stand behind his work and fix the oil leaks this time around unless i paid him again, fat chance that was going to happen. I was going to hold out and wait for more car fund money and ship the engine out to California for Henry Schmidt to fix. Henry was going to give me a screaming deal to rebuild it again from the ground up but at this time i just cant afford to to that.
So i decided to fix it myself......
I pulled everything off with out pulling it apart. Hosed it down good with brake cleaner and when i was ready to re-torque everything back together i sprayed the engine down with Acetone. The Acetone rinsed anything oily left hidden out, and is thin enough to get into the slightest clearances. It also re-goo-afied the Curil T that was used as a sealant when it was built. I torqued everything and adjusted the valves.
I drove it yesterday for about a half an hour and Ollie and i just got back from a nice long drive and i can say my car is leak free atleast for now.
The engine leaked all the time before even idling, so this is a huge victory for me.
I am going to drive the crap out of the car now
and start to really really enjoy it.
Time to celebrate - cheers-
