Youll need to take it to the track, then you can find out how much HP your getting to the rear wheels.

Maybe you mean dyno ?!?!

Track is a very poor indicator of RWHP

With all the mods listed in my sig i dynoed at 243RWHP but that was in 98 deg heat with 100% humidity here in south west Florida. Also I am a auto. With thoes mods on a 99-04 GT with a good dyno tune I would say that you will put somewhere between 250-270 RWHP. This is just my guess on a 5 speed car. Do you have a Buillit mustang or just planning on putting that intake on what ever GT you get? The reason I ask is because it will not be cheep to install that on a GT, also if you were going to install that intake on a GT I would suggest that while you have it all apart you get the heads P/P before you put it all beack to gether and you could be pushing the 280-300 rwhp.

Diver,
No i dont have a bullit, in fact i dont have a 4.6 GT yet just trying to figure out what i want to do. I know the intake is pricy. Its like $800 but if it gives a significant power boost then that would be cool, and thanks for the info bout the heads i didnt even think bout that. I mean of course I want a 03 cobra but im thinking that 300 rear wheel horsepower is enough for me and i can always superchage the GT later so. I dunno we will see.

The intake is going to cost more like 1200 before you get it all done.

Some cams and p/p work are much more cost effective, but if your stuck on the bullet I am guessing 280-285 RWHP. With just mild cams you would be closer to 300. With bigger cams and head work, you could be in the 320+ range.
