17PSI is a little excessive... I don't know that I've ever heard of a supercharger giving that high of a psi... Are you certain the gauge didn't malfunction?

17 psi sounds like cam angles are incorrect and pressure is building up on the intake side and not being used to make power with the increased exhaust flow you opened up.

I cannot think of another reason for that to happen like that.

I'm sure it looks good, but i picked up 30 horsepower on a supercharged mustang by changing the cam angling by 3 degrees. There's wiggle room here lol.

Matt knows what he’s doing. If he says it’s good I’m going with it.

17 is just the peak?

Or are you showing 17 psi at 3000-6000 rpm during a wit pull?

It’s just creeping up there the last few hundred RPM as best I can tell.
I’ll get up on 99 this weekend and do some more logs. Maybe it will be dry by then.
