Cam choice for supercharged 4.0

Post by arg0413 »

what are good cam choices to be used with an efi supercharged 4.0? What kind of gains are seen with a cam on boosted applications?

I'm interested in this as well. Not just for supercharged applications, but forced induction in general. I realize supercharged vs turbo still be different.

You basically need a dual pattern cam with a longer exhaust valve opening duration, a shorter valve overlap, wider lobe separation angle, and more valve lift.
The CompCams 68-232-4 would be a suitable candidate.

With a valve spring upgrade, and ideally with some porting I'd recommend a Comp 68-235-4 switched from 111° to a 114° lobe separation angle.

This has been a very versatile camshaft and works excellent in boosted applications.
