That car is going to be scary fast with a 10psi launch, 1.2x sixty and enough gear to run out the back door.

Heard it here first....go 3.00 in the 9.

Yeah, I was looking for something lower numerically also and went with the 3.40 pro gear as well. I think it will be enough, just may have to run the revs up a bit more.

Only at 7700 rpm and zero converter slipage.

10% slipage and you would need to go 8400 rpm to go 200mph on a 30'' tire with 3.40 rear gear.

10% is possible, but might be tough when you are putting 200mph horsepressure to the converter. The lower ratio gears and the high rpm will help lock-up, but 3.40 and 30 inch tires will be testing your converter and building serious heat in the engine and trans. It will get worse if you only have two gears.....

Very nice -- I went ahead and added you to the list. I know you'll be move up fast...

Pull the chute? It has to feel great to feel that turbo pull all the way (well at least until to the 1000').

Stall? 2-step? What rpm are you launching at? Do you have an "RPM" assist-shifter or do you shift it yourself?

On your build post, you sold your 88. What are you running now?

Anyway one heck of build. Congrats

David
