None taken. Everyone has been duped into the "15% manual, 25% auto" numbers. Or anything to make thenumber fit what they think their engineshould be making. You;d be surprised at some of the "% losses" I have seen!

The guy with the 383 stroker TBI in a 87 Chevy truck. Supposedly it was a 360hp street machine! (as quoted by the engine builder...) It made a whopping 156whp. I tuned it and got it up to 175 at the peak and it gained 40whp at 5000rpm. Add back 80% drivetrain losses to get the 360hp???? LOL! the engine made a good 225-230, which is about right for a (basically) 383 2-bbl. (I doubt it was even a 383 to this day)

Nice exhaust housing choice...make sure you are in diapers when you get into the throttle bwhahahaha...

I haven't read the whole thread, but I am curious what is the engine management you will be using. Pls don't tell me stock PCM on such good work also maf?

o.k, I won't tell you.

LS1 MAF, (gutted divider).

I found to turbocharged400, thatI will have issues with the manual valve pisition switch int he -80E vs. the 65E, so I will be running the 4T80E of a stand-alone 4L80E diesel tcm with Tunercat tuning software. or atleast, that'* the plan as of now...

Should I assume daily driving is part of the plan? I guess it depends on how much Hp you are planning to be pushing...

My current daily driver is a 450hp '88 Grand Am Turbo. It is manual steering and while it has a great heater, it'* not a real good winter car...

Yes, I drove the Bonne for about 6 months from Nov. 05 to June 06. It has been in project mode ever since. I do plan to drive it daily. This is the car I wanted to buy back in '94 when I bought my first new car. I couldn;t afford one, so I had to settle for a '94 Grand Am GT V-6 sedan. It'* like I finally have my dream car (and the nicer looking '96 body IMHO) 13 years later.

I finished one of the wood plates, I'll post some pics later. Have to finish the other today....

Uh oh. :?

Otherwise, great project! I really like your engine bay pictures, but I don't think you've shown your new turbocharger. I may have missed it, but did you yet put in the new one?

Here are pics of the interooler as it nears completion. I need to get a radius bit to carve out the tube slots in the end. I am using clear vinyl tubing which is thinner od than heater hose so I can use an off-the-shelf (cheap) router bit.

I still need to plane them down to 1.300" each for a total thickness of 2.600. I've had the */c on the engine with that much matl under it and it clears the hood wiht 1/4" to spare!

wood intercooler

interesting idea

Engineered Performance has the biggest wood in the 3800 community! LOL!

What do you plan on running through the intercooler to cool it down? Never did understand how that worked on a setup like this.
