How much PSI?

[Barrier]

If I were to acquire a forged stroker kit, upgraded heads, and stage 2 VT cams, possibly some suspension... how much PSI could I safely run with a KB intercooled?

Oh, also before I do so acquire said KB, I probably will also get a new transmission.

with forged internals and upgraded drivetrain you could run 10-15psi depending on the tune.

no no no


it will depend greatly on the CR of the engine and what grade fuel you will be running, else you will not be able to control the a/f safely.

If the CR is high and you are runnig 91 octane fuel 6psi maybe all that is safe.

If you want a s/c then have a look at the different ones available, I think most recommend a CR of 8.9:1 or there abouts, if your new engine is 10:1 region it will be a great n/a setup but bad for boost.
