Hey, just bought a new 08 GT 5spd. Other than adding a cold air intake, what are some ways to improve HP and overall performance. Thanks for any ideas.
Yup. forced induction is the best bang for the buck minus a cold air intake.
magnacharger install can be had for $5500 or so and gives around 400rwhp. No room for expandability, but it's a good charger if you only want 400 rwhp.
as long as you take into concideration the money needed to spend on drivetrain and suspension to get it to hook... and possible bottom end; s/c pulleys are very cheap and tempting!
unless, of course, you just want it as a novelty to show and spin, and spin
CAI, 4.10, and some 15' rears with drag radials will get you in the 12's and still have a reliable car; as well as give 1 or 2 of the FI guys with no traction fits all for under 2K
