Hey everyone. i'm rob, i own a 1997 mustang gt. it has a PI headswap, compression ratio is 10:1 , stock intake with filter area cut out, screen removed and k&n installed, PI lower intake, accufab 75mm throttle body, C&L plenum, mac pulleys, MSD coil packs, mac off-road H pipe, mac cat-back system, 4:10 gears, it was dyno tested with 249 hp, 293 torq at the rear wheels b4 the mac underdrive pulleys and msd coils, this was at strope speed shop on a dynojet dyno. and for some reason i think it should've made more with all this stuff, is this normal HP gain for this car with this stuff? or is something wrong, but i'm using the cams that came with the heads, no porting, stock intake and stock tune. car ran 14.01 @ 102mph at pittsburgh raceway park on street tires and spinning horribly. anyone out there that can help me out please feel free to message me with any tips, again my question is is this normal hp gain for this car? or should it have been better?, Thanks again, Rob.
