Looking for an estimate on horsepower for my recently purchased gt. Specs say stock hp is around 260 or so. The guy I bought it from put on a magnaflow catback exaust bbk Cai and 70mm throttle body. Just wondering how much gain all that adds. Next mod I'll do is probably a bama tune. Thanks!

 

Id say between 10-15hp over stock. So maybe 270-275 at the motor. My guess anyways.

My 03 gt has full exhaust with long tube headers, UDP, cai, and a bama tune which i will only use if i put 93 in it because it sucks otherwise.

Im guessing mine might be around 290hp at the motor.. 250-255 at the wheels maybe?

 

245ish to the rear wheels

 

Agree with ub. Also OP a bit of advice. 2vs and bolt on's are like oil and water... They don't really mix. What are your plans for the car?

 

Agreed. Glad mine had bolt ons before i bought the car so i didnt pay for it!

I think a full bolt ons 2v is around like 270whp probably

 

So besides bolt ons what do you guys suggest for some moderate HP gains? My goal is to get near 300 motor

You mean to the rear wheels right? If so, full bolt on, heads and a good set of cams will get you near your goal. Just to let you know you are going to spend a nice chunk of change going that route. Might wanna think about piecing together a Supercharger. It can be done for under 2 grand and with the right set up you can be between 350 to 375 to the rear wheels.

 

I believe you mean 300 hp off the crank? Not wheels? If im taking 300 motor right.

There are a number of ways to that goal. A few bolt ons, cams and a tune would do it. A supercharger like stated above. Or even the cheapest route, put a 75 shot on it and youd makemore than 300 at the crank. And a 75 shot isnt stressing your bottom end much.

 

get a supercharger and be done

 

Put some 4:10 gears in it and then add that 75 shot and hang to F on..
