Header pics really blurry, used my buddy's phone to take them. Got a great deal on them!

And last one is my new summer dd

 

Got a decent amount done!!!

 

Very nice build. Where did you get that gauge panel???

 

I got it from classic dash, it fits ok. If you buy one be prepared to cut the dash up for it to fit

 

Ok so i havent updated in a while so here goes...

Ignition.. running an msd 6al2 box and pro billet i have laying around. Will be locking timing @ 19 degrees to start with.

Wastegates are ordered, theyre tial 41mms with 1.1bar springs(16psi).

Drains and feeds are done.

Sent in a torque converter request to ptc for a 10" converter.

So the motor should be in by the end of the month!

 

19 deg is weeeeak lol All depends on what the combo wants tho, start small and ramp in. Does the box have a boost retard function? Be nice to just pull a degree or so per pound boost and just set timing at 30-34 deg for off boost running...give or take. Depends on heads. I run nearly 36-38 deg everywhere up to 6 psi before pulling. New heads need timing. Old combo with AFR's would have blown up at that level!

 

Remember im iron heads lol, and 35 minus 16 is 19 degrees lol and no retard function, im locking timing. Max timing would probably be 22 or so im figuring

 

So you are just locking timing at 19-22 deg, for all rpm ranges and conditions? The way you have it 19 at boost will be an ok starting point but at off boost low loads its way low

 

Yes all rpms, by locking timing i will save a bit of$$$ and theres no boost retard to worry about failing. It shouldnt be that bad off boost... i hope lol

 

Just worried about egt's with low timing. When you break in the motor i would obv limit boost as low as possible and give it more timing, closer to normal. Then you can back it off for boost.

I wonder if you can get a simple vacuum advance distributor and set it to 19 deg or whatever at no vacuum and have it add 10-15 deg while in full vacuum. Have a strong checkvalve inline to prevent boost from pressurizing it

 

So i ended up picking up my dads 72 chevelle. The motor will now be going in that and the 14:1 406 in the 91 camaro. I found a local machine shop that has a dyno ( riverside engines in tiffin ohio). The next update will be dyno numbers. Im shooting for the 1000hp mark!

 

Well i went to riverside yesterday to set up dyno time and they dont have it anymore so im sol. I guess there wont be any numbers until i make it to a chassis dyno.

I went with a tial q bov. Also picked up holley dominator pump and hobbs switch for the second pump, and some little odds and ends.

 

Been a while since ive updated... got the car fired up today, i dont have the whole fuel system so i ran it off the bowls. The motor sounds great! Still needs lots of stuff before its driveable though...sadly

For those of you that have never smelt e85, its some nasty stuff!!!

 

Been a long time since ive updated. Got the car finished and waiting for the weather to break to take it out. I turned the boost down to 7psi for fear of this 807 casting 400 breaking. I also added the msd btm add on box to run more timing out of boost. Changed to a eaton truetrac, 30 spline mosers, and 3.08 gears. And im now on 4 corner disc brakes. Timing is locked at 36 degrees pulling 2 degrees after 2 psi. I will start adding timing after it comes out. Should be a fun car nonetheless

 

I just read this entire thread, looks good, post a video of the engine running, I'm not a turbo guy, I prefer Blowers or engines with high compression on race gas.

Looks good, looking forward to more updates!

 

Thanks!

Im having a bad overboosting ordeal so im trying to work that out. Im at 20 psi in first gear at around 3k and wastegate springs are 7.25lbs. Ordered 3.6lb springs and ill try running it with those next

 

Maybe a stupid question, but do you have a boost reference hooked into the wastegates? Usually this is a vacuum hose going to the bottom port of the wastegate relaying pressure from the compressor, cold side piping, carb hat, or even the intake manifold. If so, do they actually open if you put 7psi in them? I don't see them being too small of a size wastegate, but it looks like they only bleed off exhaust from 1 or 2 cylinders which is not quite ideal either.

I had an undersized wastegate situation once running a pair of 38mm gates, which is why I now run a pair of 60mm gates without issue.

Well here is the issue!

http://www.theturboforums.com/thread...oost?p=1923994

 

Even bleeding 2 cylinders like my old setup shouldnt see overboost by much more than 1-2 psi. I'd check springs rates and vacuum lines to be sure

 

Im getting boost source straight from the compressor cover and i even cut the one down so one is like 8 inches and the other is about 4 inches.

Its insane that i build that much boost so fast with no springs in the gates. Its def a piping issue. Im pulling the motor out this week to replace the rear main seal so i will have a guy from work in the millwright shop open the i.d. of the wastegate piping up and cut the primary open to open the wastegate merge. Should fix it!

 

Yeah try to get it in a better location near the turbo inlet if you can. 1.75-2" pipe

 

Actually im not changing the setup im just opening up the pre existing pipes. It actually has all 4 pipes to the wastegate. The headers are a 4-2-1 design. Anyways, where the pipes are welded they have a dime size hole that needs opened up and there is 2 of these per side. Trbo355 in the link explained it but you would need to see how these headers are in person or a better pic for sure!

i really do appreciate the feedback!

 

Makes sense. A true 1.75" for a 38-40 mm gate should not have issues. Dime size hole yeah... Thats not gonna work
