just fine. get a tune even for 5psi. Also get an IC and you can run 5-7psi just fine.

what do you think the car would run with stock with the sts a stalled th350 and a brake behind it, and 3.73's out back?

run as in 1/4 mile? Depends on alot of variables.
Ditch 3.73s if you can. Get a 2 step, and get at least a T67 or bigger.

snaketamer

why do you say ditch the 3.73's?? what would everyone suggest? the two step will come when the new tranny goes in as well.

turbos dont necessarily like high gears. they like load, the longer the gear..... the more boost you can have

i remember when i put 3.73s on with my big block. first gear became useless...

i WOULD NOT put 3.73's on a turbo car, the lower the better. but you dont necessarily have to do 2.75's. IMO, 3.73's are more of an N/A gear

3.42 is considered the best 1/4 mile gear for a 4L60e.

We ran our original prototype LT1 STS kit back in 03 for a year and a half on 5psi and 7psi (with meth) before we finally decided to just forge it to go bigger boost. We now have it at 15psi.

If you get a good tune, you'll be all set for a long long time.
