Default Horsepower estimate?

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?

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

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.

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