How much hp can my stock internals handle? Im asking because at the end of the summer im getting the Procharger Stage II P-1SC Intercooled Kit and i wanna knkow how much boost/hp i can run on my stock internals.

 

I am running 11 psi aftercooled and pull down 390 RWHP.&amp\\;nbsp\\; It really depends on a tune but a good rule of thumb is&amp\\;nbsp\\;400-425 rwhp&amp\\;nbsp\\;max.&amp\\;nbsp\\; Anything other than that you are pushing it good tune or not.&amp\\;nbsp\\; Generally, 8 non-inner cooled 9/10 inner cooled.&amp\\;nbsp\\; Mine is 11 psi that can with the kit directly from Vortech.

 

stick with about 10lbs stock pistons suck

 

k how much hp will i get with 10 psi in addition to the mods i hav in my sig? In the 300's 350?
