I have a 2001 GT 46000 miles with SLP Xpipes, MAC Catback, K&N Filter, Diablo Sport Tune, Steeda short throw, Eibach springs, 373 gears. I dynoed at 245 rwhp 288 lbs of torque. I wanted to get more horsepower and was thinking of doing a supercharger next, I wanted to ask what is involved in this, what else do I have to do other than just putting the Supercharger in? What kind of $ does this usually cost and what kind of power will I see?
Oh yeah I have Firestone Wide Oval Tires F 245 45 R17 R 275 40R17 which i am already having lots of trouble hooking up with my gears.

You have to get bigger injectors (42's cost around 300-400), focus or IMO go with the aviator fuel pump, and just get a tune from a respected tuner in your area. If you want more power a 75mm throttle body and plenum like C&L, Accufab, or Dragon will help you get a little bit more power. With all that you can easily get 400rwhp and torque. It is all in the tune on how long the motor will last, so don't cheap out on one that cost 500 over somebody that charges 100. You get what you pay for.

For the Kenne Bell probably $6000-$7000 installed, I sunk about $8500 with welded full length sub frame connectors, gauges. Comes with chip and injectors. Complete less plugs. Should see around 400 lbs and 400 hp. Very flat torque curve.
