Procharger Pulley size question
Hey guys, I'm working on getting all my ducks in a row before I install the procharger I just bought. It's a p1sc-1 and it's going on my 6.2 sierra. The kit came with a 4.5" pulley. The tech I spoke with at procharger who said my truck with 1 7/8" longtubes and 3.5/4" exhaust will only make about 2lbs with the 4.5" pulley. With my goal of 8lbs of boost the tech recommended a 3.85" pulley. Does this sound accurate? Thanks in advance guys.

Well what is your crank diameter and what is p1 max rpm (58k i think). With a 3.85 where will that put you?
Compression on motor.? How much do you trust your tune? Are you running meth?
I think you would probably be maxed out on a 3.5 so dropping all the way down to a 3.85 from the start might be a bit ambitious, but if you want to i got an 8 rib 3.85 ill sell you.

If your running a stock size crank pulley then the 3.85 should get you get you close to that range. I had a 3.8 on my 6.0 and it didn't make 10 lbs with the P1. The 4.0 will make less boost. Your running a free flowing exhaust, good flowing heads. Boost is a restriction, so more isn't necessarily better.
