I have a 2003 mustang GT with the following mods--CAI, C&L plenum, 75mm t-body, U/D pullies Diablo tuner and a Cat Back exhaust and a 4.10 frpp gear --Should I be making around 290-300 hp at the crank or am I crazy? If not how much HP should I Expect when I go to the dyno this weekend?

stock you are at 260 crank. those mods wouldnt give you 40 horses. My generous guestimate at the crank would be 285. 10 hp for your intake stuff, 10 freed up from UD pullies, and 5 for your exhaust...again thats generous

Well on the dyno you will probably get around 230rwhp. But yeah at the flywheel about 185 would sound bout right.

throw some LT's in there and you will probably break 300 HP at the crank.
