What’s up guys, getting that itch for alittle more power. So I’m looking to up the psi on my sos stage 2 kit for my ap1. I’m currently at 10 psi making 380 whp and 232 tq. My real question is what can I go safely to I’m torn between the 13 psi and the 15.5 psi 3.6” and 3.4” pulley I’m on the novo 1200, aftercooled and race heat exchanger.

my concern is I want to safely do this I don’t get on it ALL the time but definitely red lining now and then. Fuel system is id1000’s walboro 255. Is 13 psi worth the jump or just go to 15.5 psi? And what HP am I looking at.

Thanks in advance!!

3.2" pulley and send it my guy.

Just watch Data (afrs timing) adjustments.

Haha that’s what I’m thinking

Whats up chief! That’s what I’m gonna keep an eye on as long as all checks out I’ll be happy! I’ve decided to go with 3.4” pulley which will bring me somewhere in the 15 psi range. 13psi isn’t worth the trouble but 15 definitely

Figure about 15 rwhp for each psi.

If you want a tuner to check it out, lmk

15psi, 11.5:1 compression, 91 octane pump gas?

Nick2t1me

I’ll be running 93 octane for now , e 85 coming next summer
