if i got a procharger for my 350 pushin 4 or 5 pounds would i need a bypass valve or intercooler?
I'm assuming you mean a Blow Off Valve (BOV)? I don't think you need one at that PSI, but an Intercooler always helps lower inlet temps, which can be good for some more power.

This catalog by Procharger is great. I learned a lot from it when I was trying to figure out my combo. Page 36 talks about BOV's and when they become necessary (8 psi). Page 26 talks about intercooling.

Read away! http://www.procharger.com/catalogviewer/index.html (Open the "Card Chevy" catalog).

Im not tryin to be the suzy downer of this convo but is a supercharger putting out 5 psi worth it? Im not talking from experience because Iv never drove a forced induction anything lol. Would you see a big boost in power from 5 psi? This is more of a question than anything
Oh yeah, every additional psi is worth it. Example, a well built SBC with 10:1 compression would probably make about 450hp. Now add 5 psi boost, the compression is now almost 14:1 the boost, now you have a 14:1 SBC 400 makin 600-650hp.

And you just went from premium to race fuel lol
Yeah, that was a bad example, LOL!

More like 8:1 compression base and 11:1 under boost so you can still run pump gas.
