ok, I have searched and searched so i now I'm gonna just ask...

I have a p600b that I am putting on the 355 I built for my boat. My question is what pulley's do i need to make 10psi @5k? Or how do i find the info myself. I think my crank pulley is 6".



forged 355, 8.5 comp, fully ported patriot aluminum heads and intake, comp xtreme marine cam, thru hull exhaust

It is probably going to take the smallest ProCharger pulley you can find for a P600B to make 10 psi on a 3.55 at 8.5/1 with a 6.0 crank pulley.

Thanks, do you carry them? Would it help with a smaller or larger crank pulley?

Yes, I do carry them. It would help to have a larger crank pulley made, so that you don't have to drop down to such a small blower pulley, as the smaller pulley will give you less belt wrap. Bottom line: You'll have less belt slippage with a larger pulley. You can take your crank pulley to a good local machine shop and have them create a new one that is roughly one inch larger. Jut make sure a larger crank pulley will maintain adequate belt clearance around your drive accessories. Thanks. Bob
