Its all in the combo, and i think a NX 50hp shot of N2O is pretty basic...

PI heads port and polished, worth doing?

Edit: btw I have the Eaton Supercharger and Comp Cams.

Oh yea....PI heads on a 96-98 need to be done. Its like upgradeing E7s on a 5.0. Damn, I hate E7s. I wish I could put the same heads I have on the notch on the GT.......

But the problem is I wouldn't have the money to switch superchargers. I'm pretty sure my kit is for non PI heads. It's the Ford SVO Supercharger kit.

Maybe porting and polishing non-PI heads?

You could. Another thing you could do is try to sell your current set up. I have sold head/intake combos in the past on e-bay. Maybe post up your supercharger on e-bay and see what happens. Some people would rather hear it and see it on a car before they buy it anyway!

One more thing.......crownvic.net Those guys will jump on that. They are into those cars more than we are into our mustangs I think! The vics didnt change to PI untill 01 or 02 unlike the mustangs did in 99. Try it!
