I just ran into some luck, and got this car. I'm just looking for some simple answers. I hear these cars make stupid power w/ little effort. So im wondering how much I could gain from a pulley, intake, exhaust, and a tune? Also, does anyone know how much power these cars really make stock? I hear 390, but i keep hearing that its underrated. Thanks!!

The guys over at svt performance.com answered the same question for me. Stock 03/04 Cobra are being dyno'ed at 405-415 hp. With the mods your talking about you'll be in the 475-500 to the wheels. I'm planning on doing the same mods myself!

That's 03/04 Cobramotors dynoed asflywheel horsepower isn't it.....not rear-wheel horsepower.

The wheels are being dyno'd at 360-375 range. I'll let you know shortly. I have some bolt-ons on order, but before there put on I'm getting it dyno'd first. I want to see my numbers from the start till I'm done modding it!

Mr_Cobra

Most will put on 360 to 380 some seam to be a little higher. Mine was 387.7 HP with only a K&N air filter (not FIPK) W/ 373.5 Torque. After my mods i had 457.2 Hp with 468.6 Torque

Those are great numbers stock [:-].....your 03/04 Cobras are basically delivering the claimed horsepower to the rear wheels. With the 15% loss through the tranny, your motor numbers must be well over 400!

I had my dynoed today. I am currently putting 384.6 to my rear wheels, bone stock. I can't lie..I was shocked.
