I have a 98 GT. I've never been to track, but my car will soon have these mods: PI Intake, Heads, and Cams, MAC LTs, BBK X-Pipe, Flowmaster American Thunder Cat Back, Shifter, and UD pulleys. Anyone have any idea what kind of horse power numbers i will be creating with this combo. One thing i am sure of is that i HAVE to get gears SOON. Would be a stretch for me to think that i will be close to the 12's with this combo if i add slicks and gears?
