im new to the site and just recently purchased a 04 mustang gt 5sp. i added a k and n intake, 3.73 gears and a hypertech tuner to start with.im about to put some serious money into it and wanted some input on what works best and about what horsepower at the wheels i might see after a good tune. im thinking about getting kooks headers, slp catted xpipe and flowmaster 40s catback, patriot stage 2 heads and comp cams, underdrive pulleys, 75mm throttle body and plenum.just curious to what i might see at the wheels for hp and torque and any suggestions on some good parts that have worked for others. is it unrealistic to see 300 at the wheels going this route???i know thats a hard number to get unless u supercharge it or use spray...thanks for any input

Sounds like you have done some thinking already! Welcome to the site by the way!

I would expect around 260-280 at the wheels. But you could get lucky! Go to a mustang Dyno though. If you hop on a dynojet you could see numbers that say 310 horse but that is VERY unrealistic. Plus the Mustang Dyno will give you a slightly better tune.

Anything else?

i think you could get close to 300 rwhp with the right tune! make sure to have those heads checked out by a ood shop to make sure everything is right on them. you may also choose to change the patriot springs out for the comp springs as rthey are much better. a lot opf people say the patriot heads are crap but they are a decent product. they are arent anything exotic or really special but they work. people say they suck becasue when they first started they had a bad run but they have cleared that up a long time ago and are now making quality stuff. also like ck said, the dynojet will give you a higher rwhp figure but the mustang dyno is more truwe to the realness of the power. the dynojet measures everycar as if its the same car. with the mustang dyno they can add in aerodynamics forces and other stuff to get the right tuneanyways lets see some opics of the ride

If you go much further than you are planning for now, watch the lower end of the engine. If you want to drop some serious cash I would replace that as well since you have everything else in the works...
