Thanks for the feedback Grady...15 RWHP ain't too shabby.
I plan on going with Trick Flowheads and a matching Trick Flow cam. I guess I should have posted that the specific intake I'm considering installing now is of course the Trick Flow Street Heat. This intake will be installed eventually; this year by itself or next year with the heads/cam.
My goals are as follows: 12s this year with my nitrous, gears, exhaust, and bolt-ons combo. My car has also been on a serious diet. This should be attainable, as my first time at the track netted a 13.34 with several ****ups driving wise on my part. 11s next year with TFS heads, cam, intake, 30lb injectors, throttle body, stall, and the same old 125 shot.
I'll consider the intake manifold only for this year based on your suggestions.
