Hey guys i had my GT dynoed yesterday ... and I peaked at 240 RWHP at 278 Torque.. I was hoping to get those numbers considering that i only had a cold air intake and accufab plenum with 70mm TB... my goal is to try to get it at 300 Hp if not close to it.... any suggestions on what else to grab for mods?

I am assuming that you have a manual transmission. When stock, these dyno around 218 rwhp. That means that you've added 22 rwhp with just intake mods. That's great! A mid-pipe will give you another 8-10 rwhp, while LT headers will gain 15-20 rwhp. The catback exhaust will be around 6-8 rwhp. This totals an additional 29-38 rwhp. A dyno tune with a performance chip might squeeze out another 8-10 rwhp. Assuming the best, you could gain an additional 38 rwhp, putting you at 278 rwhp. To see 300 rwhp, you will need either p/p heads or a custom cam, preferrably both. But now you are talking major bucks. I dynoed at 250 rwhp with my extensive mods (see signature below). It would have been 260 rwhp if I had a manual transmission.

what kind of intake do you have?
 
I have a Mac Cold Air Intake.... Also I was told by the guy that was doing the dyno .... since my car is brand new (1800 Miles) 04', he said that the car may add more HP once the motor is broken in ... like about 5000 miles... My next mod would be a bassani Catback and X-pipe, i was gonna do underdrive pulleys but i heard its bad to have in the long run.. im hearing that the motor doesnt last long with it, so im hesitating about that ... but .. cams are must, and some exhaust... thanks Guys!!
