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? Also

My friend has a 04 GT that is about 350hp and about the only thing he has in addition to what you listed is a cold air intake, so I would expect somewhere in the low to mid 300s​

I call BS on that claim, he is not making no 350 at the wheels with just those mods. The highest dyno I have seen with those mods is 274rwhp. Your probably close to 265rwhp.

^ I agree, I don't think you'll see 300hp bud. I have all the mods you have and plus a o/r mid pipe and I'm guessing I'll see around 255-260hp when I go to the dyno. (Mines an auto)

I don't think so:headscratch: The dyno he went to, to get his car done must of been way off.

With a CAI, Cat back and a SCT X-Cal tune the highest I have seen was 271 rwhp, on a cold day. If you estimate a 15% loss through the drive train I would guess 305-315 at the crank.

Dang, and i thought it was kinda easy to get to 500~ HP. A friend of mine was selling his terminator that had over 500 horses under the hood. It was put on a dyno, yes, i saw the papers =P. One day, I will be there after i get a a 5.0 rebuilt, ill put money into parts for my stang!

To clear things up man, I have a cobra clone (in progress) that's why my numbers are way low to be a terminator lol. It's just a GT with cobra costmetics, I plan on going FI later and make close to 400hp when my budget allows it, but before I go into that I'm going to work on my suspension.

Good luck on getting the 500hp beast going, let us know how it goes:bigthumbsup Should be a monster on the streets.
