I ran the 12psi on a comptech btw

 

I have been running 11psi on stock compression putting down 377whp on a dyna pack dyno. No problem at all. It can handle it without any problem

 

15 psi on stock AP1 is no problem..Axles and clutches than come to be problem.. 1 bar is pretty ok with the AP1.. if i am thinking i think the ap1 can handle a bit more.

 

just do w.e your tuner thinks best

 

how much you putting down on 1 psi and ported n polished head?

 

The 1220 blower used on the SOS kit is the same as the 1200 minus the impeller. Change that out and its good for another 5 psi. I can make 12 psi If I run up to 8200 which I don't like to do. 3 want to make 14 psi at 8000 and stop there.

Just wanted to run it by the forum and see what people think. I don't drag my car, only race is a little street run now and then from a 2nd gear roll.

I don't want to kill my car but always like more power, especially more at lower rpm.

That said, I love my SOS kit!

 

^^^ I run my stock f22 to 9k almost daily without a wimper. Hell, theres another free 15/20whp on the top end if you let the motor rev. The valvetrain is stronger then the f20 and short burst up to redline isnt going to hurt anything on the bottom end, its already underated at 8k rpm, 8500rpm is the matched piston rpm on the f20. I think your short changing yourself if you stick to the stock rev limit with an SC if the motor can take it.

 

Vortech S/C ,3.7 inch pulley, water/meth 50/50 mix (AP2 motor swap) 11-12psi

 

i run my roots blower up to 10 psi on a stock f22c. i see 11 psi in really cool weather

 

Have you dynoed yours? I'd be interested in seeing your HP curve.

My multiple dynoes and others I've seen run out of steam around 8500rpm - AP1/AP2 alike. There's no reason to wind it out if you're looking for max HP.

With that said, I've been known to bang against the redline every now and then.
