Kenne Bell 2.2 Pulley Setup

I am going to be having a kenne bell 2.2 put on my car soon, but am unsure which pulley combo id need to be making around 18-19lbs on 93 octane. I have a 3.5 and 3.25 upper and a 4lb lower. Not sure if either of these combos would work? I have JBA Mid-length headers, and catless exhaust. Stage 3 cams(previous owner doesn't remember brand). Any recommendations are much appreciated!

I had Kooks LTs, Kooks catless midpipe, and bassani catback, Crower stage IIIs, and a 302 Stroker and I used a 3" upper stock lower and saw 17psi.

I have 4lb lower and the blower comes with a 3.5 upper on it, not sure where that would make me end up lol. but just wanted to make sure I had the correct pulley setup for install and not have the thing up on the dyno and make 11lbs

I have been there. My 2.2L was pulleyed for 17 and I saw 17. Swapped to a 2.8L and pulleyed for 18.5 and saw 14.5...

You are pulleyed for 17. I can not guarantee you will see 17 and would expect you to make in the 15psi range with your mods.

^15ish agreed. Either way, the 2.2 will scream.
I'm a 3" blower with a 2lb crank seeing 19 on stock logs and cams just as the chart above predicts so that further confirms its accuracy.

so if I wanted 17ish I should get a 3.25 upper and if I want 19ish a 3.0? I guess its more so trial and error. I just don't want the car to be done and on the dyno and have to order a different upper pulley an wait a few days before having it finished up. maybe ill get a 3.25 and call it a day lol
