So, I'm assuming you don't have the race cover on the 76 unit now? Fitment will be rough with the race cover if this is a full accessory street car. If not have at it. Yes that will get up and go a bit more depending on your A/R's as well. All in the combination though. Good luck.
the 76mm has no race cover the a/r is 1.32 the same for the 76 and the 82mm and no combination change before the car ran 9.2 at 147mph on 16psi but i try turning the boost and makes no diffrence what so ever and i am limited to 20psi so i am hoping it will make a diffrence when i boost it up with 82mm
