P1SC owners
my goal is to max out the setup, no meth just pump gas(91octane) someone stated above that a build motor isn't required for p1sc but I had no choice on the rebuild but should have stuck with more compression (9.1) I guess a d1 or f1 is in the future

damn, i'm runnin 7.5 lbs on a 3.5 pulley and a stock bottom end, full exhaust, 42 lb injectors and i'm running 500 horses. i think its about time to get rid of the 4:10's though, when i'm really gettin in it i'm not in any gear for more than about 2 seconds. hmmm 3:42's maybe?

Might want to think that over long and hard. I had 4:10's in my stock 10 bolt and thought the same thing. Threw in a Midwest fab 9" with 3.90's and absolutely HATED!!! it. Made the car feel much slower and I lost 2-3lbs of boost. I paid the extra $500 to have the 4:10's installed in the 9". Just an FYI.

But if at 5k RPM you make 6psi it doesnt matter if you have 2.73 or 4.10 gears you are spinning the supercharger the same speed at 5k RPM thus giving you the same boost!
Boost is relevent to RPM so it soesnt matter what gears you have your gonna make the same boost at the same RPM. and gears doesnt give you higher RPMs... You just get there faster!
To the OP, don't forget the inlet restriction of the air filter that comes with the Pro Charger kit. Do some searches, you'll find there are big gains to be had in fixing that bottleneck. Also look into converting to a FMIC, like the one offered by EPP, my understanding is that the twins that come with the kit aren't necessarily the best case scenario either.
