Centri Superchargers... max psi? i know that most of you guys run low boost 5-8psi on your engines. i noticed on the ATI website that the p1sc1 can push 32psi max. i know i can just go turbo and push that much easy. anybody ever taken any centri to about 28psi? or that even possible. let me know whats up. thanks
#'s of boost is just a measurement of restriction. One engine might make 500hp on 8#'s of boost and some might make 500hp at 15# of boost. It all in the set up. PSI doesn't mean any thing.

im talking about the head unit itself. is it possible to push 28psi out of one? thats what im looking at here. i know you guys know a lil more about centris than my community
I guess so....if I am seeing 16psi with a d1sc......then I guess you could see 30psi on a motor that is half the size of mine
28 PSI is MEANINGLESS. The volume of air it moves is important. I can cap the outlet and prolly make 30 psi inside of the blower, but that is a useless value.

I think the only people on this site that are familiar with Rotrex is Kurt from W2W (no longer in business) and I. And that's only because I happen to own a truck they installed one on. 30psi out of a p1sc? on your car, maybe..but I doubt it.

I got 14psi from my P1SC on my 346 with stock truck heads. That was spinning the P1SC to like 98% of its max RPM. You wont ever see 30psi on a V8 from a P1SC. It may make that much boost on a 4 banger tho. As has already been mentioned here, the boost# by itself is useless. It will depend on the engine combination such as cam, compression, and the biggest factor would be displacement. Had I been running the exact same pulleys on my P1SC on a 427 it would have made wayyyy less than 14psi. Its all relative.
