Question...
 

Alright gotta question for you guys.....Is there any way to get my 03 GT up to 300+ rwhp without a power adder? (Supercharger, Turbo, Nitrous) I know it'd probably be easier but i was just wondering if there were any combination of mods that would work. Thanks for you input.

YES! But it's not easy, you'll have to get your head's ported, stage 2 cams w/springs, long tube headers, and just about every bolt on you can find(TB,Plenum,exhaust,pulleys,CAI) Then a good tune. I'm not saying it's impossible without ported heads, but it's the easiest way.

You might also need a ported Bullitt or a P-51 intake manifold. Several guys over on Modular Depot have gotten well over 300 RWHP NA. :icon_thum
