ok mp62.......so at what rpm of the charger does it become ineffiencent and what pully size puts it at that point and that is what psi of boost?

I am getting 10-13 psi usable boost on the 3400, the drivetrain will fail before the SC does in my case. Temperature rises only 8-13 deg. in a 1/4 mile run, depending on ambient air. Boost level will decrease a bit as you make the exhaust less restrictive. 2.0 pulley, 5800-5900 rpm shift points. Somebody else do the math.
