well i just went through this entire build thread!! very cool, and it is great to finaly get the build thread and info on the FAMOUS dyno video of the 332 turbo motor!! that video has been floating around the internet for a while...

very cool build i am looking forward to see what your new setup makes..

very cool build man, i love destroked motors, and with a t56 that is great..

i am still leaning towards a t56 twin turbo car when i finaly can start building.. unfortunatly my builds is on hold due to a bad car accident.

any way keep up the good work, and the updates when you can..!!

very inspirational build!! thanks

Thanks! Yep the old dyno video made the rounds for sure. I wish I would have been able to get a little more dyno time with that engine at the time, and then get a video! It would have been fun to have it show a little closer to its full potential both RPM and power wise.

It has been a fun build though, pretty fun to get some exposure for doing something a little different, and do something that a lot of people want try or at least see somebody else do!

Nah I get it that all the time! I don't know why it was made it like this, but it is what it is, they are the fuel rail hold downs. I will be making a different sheetmetal intake for the car at some point, but this one works for now.

As far as the car goes, I got a Monster Stage 3 lightweight twin disk on order, so I can't wait for that to arrive so I can drive the car with a functioning clutch again! The Spec is working and holding, but it just doesn't disengage no matter what I do. There is an electrical issue I am sorting out as well, I believe my wiring fuse/relay board has an issue, so I have to figure that one out. New JGS 50mm wastegates will be going on shortly and it will be ready to make some big power pulls, and be a dyno queen for a while, until I can get new wheels and tires to make a track trip worth while!

Would that make it a situation where there is..... Danger to manifold?




More seriously, awesome build and can't wait for some 8000 rpm videos!

Finally have a little update again. We had the street machine nationals up here this past weekend and I got the relay board back from being fixed just in time to have it ready to go to the show and throw it on the dyno.

I pulled 1,017rwhp on 20psi Friday. I tried it again on Saturday after Nate showed me up with his TT Nova at 1,050. I wanted to see what more timing would do, so I put 1.5 degrees in it for 17 degrees total up top.

It made 1,055 first pull, and 1,070 on the second. So all in all not too bad for 20psi. I have to figure out my fuel pressure drop issue, it drops to 40psi on the top of the pull, so a new pump setup might be in my future.

Sounds good pulling to 8400!

It's funny how butt hurt people get when you talk about destroking a motor, but they would give you nothing but praise if you titled it overboring a 4.8L to 4.02" bore.

Awesome numbers, great build. Glad you didn't let the fire put you down. Like a phoenix, but way different.

The first setup with the PT8847 and 9.5:1 332" engine was with a stock 0411 PCM with 3 bar setup. With the twins and high 12.5:1 333", I switched to a Holley Dominator.

Working on getting an update together for this thread again, it's been a while. The time has come for a round of changes! Sold the twin turbo setup, and going back to a single turbo again. Same basic engine combo, but kind of taking what I learned with the first two variations and combining them for this one.

The new engine is going together shortly, as soon as I get a few more customer engine builds out of the garage.

So for now, here is a couple random pics of what's happening

Jackson did you ever max out the twin setup?
