with the power coming in that late, have you guys thought about using a shorter manifold and trying to get it to spin faster to try to broaden the powerband out? wouldn't help anything in the low end but might give some more usable rpm's to work with up top?
great work reguardless.
what kind of porting and internal work has been done to the motor?

I doubt it will make it but I'd like to shoot for 35psi.

More air will equal more power, especially at high boost! This is basic physics.
BTW i wasnt' aware garrett made a GT4788? Where are you getting this from?
Is it someone else selling it with a different name, because its not a true garrett if it's labeled GT4788.
They make two different GT47's, 4708 and 4718.
Also what kind of power are u trying to make?
