I have a procharger p1sc1. I'm planning a build of about 635rwhp (750 crank). According to procharger, I will be under the max hp limit of 825. I also calculated the impeller rpm and it will be well under the recommended max of 65k rpm.

The only issue I have is procharger states the p1sc1 to be for engines with a base horsepower rating of 200 to 450. Im guessing my horsepower NA is about 525. Will this present a problem?

 

I'm on a p1sc1 making 7 to 8 lbs and I'm making 660 whp and 599 tq. that's a on a forged ls3 with ls1 top end with meth . Im on a 3.9 procharger pulley and a 8.6 crank with an aster bracket , if those are your goals of 635 you will be able to do that . Hell if i had ls3 heads id make more power too . So you will be fine with a p1sc1

 

Thanks! yeah. you are definitely making more base power than I am so I'll be fine.
