The GT500 is better than the Cobra’s in some ways and worse in others. The motor is larger and with more displacement comes more power. At 8 psi I’ve seen stock ones put down as much as pullied and tuned 03 cobras with 15psi of boost on a stock blower. With mods like more boost the power goes up from there!
Here’s a stock GT500 vs on with pulley, intake, long tube headers, and tune:

Here’s a stock GT500 vs Ford TVS blower with 15psi and some other mods:
Here’s a stock one vs Kenne Bell with about 18ps:
Here’s the downside: These motors have decent pistons and a steel crank but the rods are longer than the Cobra’s and aren’t H beam. They are the weak link and you simply can’t get to the same 800 rwhp as the Cobra’s and have the motor survive! The GT500’s are harder to tune with the drive by wire. We’ve tuned many combinations and can help you with yours. We data log as many as 20 parameters while tuning to make sure everything’s safe and working properly.
There are many tricks to tuning these cars correctly and we’ve got over 12 years experience in doing them. We offer the same Drivability Guarantee! Not happy with the way the car drives? We’ll retune it NO CHARGE as long as there are no mechanical issues! Need to pass emissions? With the introduction of the OBDII Readiness tests in New England it’s harder than ever to get heavily modded cars to pass! We can help! Have you installed High Flow Cats and got the dreaded “Wrench” light? That’s because the emissions requirements after 05 tightened up so much that virtually every high flow cat doesn’t have enough precious metals to be efficient enough. We have a fix for this! As a matter of fact, if we tuned your car we’ll guarantee you’ll pass the test and get your sticker. We even run a “simulated obdii readiness test” on the car when you leave to make sure it’s ok.
