I will also be changing the rear end so my gears are longer as the 4.30 is causing me to have to go into over drive at the drag strip. Hopefully a 3.93 or 3.70 fixes that otherwise Ill have to raise the rev limiter. Picking a turbo was the next part, I wanted something that would still spool quick and still be able to reach the 500WHP mark through and auto trans at mild boost.
Good to see you doing it right. You know how to calculate rpm, speed, gear, and mph? I have a simple formula that makes it really close. I can tell you with the 3.73, 6000 rpm is about 115 mph. You will need to consider this if you want to run 10's. Keep up the good work. And I know you are already thinking about that trap speed with rpm.
