I was wondering what the difference is in a 1999 cobra motor and the 2000 bullit motor. I was reading 5.0 mustang magazine and centerforce redid this soldiers car. I noticed that they put a paxton supercharger on the car. I was wondering if the motors internals on the bullit were stronger than the cobra's. The reason I am wondering is because I am going to install a Kenne Bell and was wondering if the Cobra motor would handle it without upgrades to the motor. The bullit motor was all stock. Thanks guys and gals.

Actually the Bullitt engine is the same as the 99-04 GT's, SOHC 4.6 with a couple small things like better flowing cai and throttle and tuned exhaust along with suspension upgrades and brakes, so the power is about 270 flywheel. The 99 Cobra engine is the 4.6 DOHC engine, around 300hp flywheel i think. If you were wanting to run high boost, both of these engines would need forged internals. Even the old Cobra engines didnt have forged internals until the 03/04 Cobra came out with the supercharged 4.6 DOHC. I am running 10psi on stock internals and so far no problems at all. People run blowers on stock engines all the time and make over 400rwhp safely, just as long as you have a good tune for it.

thanks for the info. do you know if ford dealerships can tune?

No they dont. They would have no idea how to tune(for the most part) a modified car nor would they want to.

The 99 Cobra's were supposed to make 320hp but they did not. They made 300hp. Ford fixed this problem by recalling the Cobra and fixing the intake, tune and exhaust system if I remeber right. That is why their was only the Cobra R for 2000, to many problems with the 99.
