After i get my Pi swap and cams all finnished I would like to put an innercooledkb supercharger onmy car. I was just wondering since it will have 10:1 compression with the new stuff whats a safe boost level to run withstock internals?

 

I have heard that 9 psi with a KB is the highest you should go on a 99-04 PI motors with stock internals. Since you have an sn95 with the swap, as you know,you have higher compression so idk. They have an 8 psi pulley.

 

its not the boost level, its the RWHP level that matters....stay close to 400 much more than 420 is a matter of time before the boom

 

Alright, thanks guys.
