Anthony Bongiovanni • '10 Shelby GT500
Anthony Bongiovanni's '10 GT500 was probably the least modified car on the grounds. On the outside, his GT500 looked completely stock, but as soon as he turned the key, you knew it was far from factory.
Under the hood, the long-block was as it came from Ford, save for the aftermarket cams. The stock supercharger has been ditched in favor of a 2.9L twin-screw unit from Ford Racing Performance Parts. The stock camshafts have been replaced with Super Cobra Jet cams from JDM Engineering, which give this GT500 a super-aggressive idle.
Once the car was strapped to the dyno, Bongiovanni swapped tunes, and we made our first hit. When the rollers stopped, the raven GT500 cranked out 759 rwhp and 676 lb-ft of torque. We made another pull, which brought max power to 771 rwhp and 678 lb-ft of torque.
Bongiovanni used the rest of the session to let the car cool, but unfortunately, it wasn't able to make any more power. His last two attempts netted 763 and 747 rwhp respectively.

Chris Pilla • '03 SVT Cobra
Chris Pilla's story is not unlike most Mustang enthusiasts'. After dumping a bunch of money in an SS that was never actually a performance car, he wised up and picked up the Sonic Blue Cobra you see here. After a few bolt-ons, he decided to go to the track, and he was hooked—in more ways then one. The horsepower bug bit him, and he broke the IRS on the third pass.
Fast forward past the broken stock engine, and Pilla's Cobra has a built motor with all forged internals, ported cylinder heads, aftermarket cams, and 25 psi of boost from a 3.4L Whipple twin-screw supercharger. Oh, and that broken IRS was replaced with a Currie 8.8-inch solid axle.
On the dyno, Pilla was in-and-out after three quick runs. The first run netted 775 rwhp and 651 lb-ft of torque. With the fluids up to temp, we made a second run, which saw horsepower and torque rise to 782 rwhp and 659 lb-ft. After some time to cool, we made one last attempt at making more power, but unfortunately came up short with 756 rwhp and 659 lb-ft of torque.
