Truth in advertising????

[2NDTIME]

Could you really expect 110rwhp gain on a 97 GT with the ported PI head swap from powerheads? Anybody done this?

 

[imblown-ru]

as with any advertised power gain, probably not. maybe 110 to the motor and like 80 to the wheels....?

well, since its going from a Non-PI head to a Ported head, them maybe*(highly doubtful imo). But like imblown said, no way at the wheels.

chances are they tested the car with their heads and a bunch of bolt-ons (maybe even cams?), and compared the numbers to a stock non-pi GT. Dont believe manufacturer claims until you see the part dyno proven.
