Jeff Scofield is not one to do anything slow. He’s owned the gamut of performance cars, but this 2014 Shelby GT500 has shown to have staying power. Scofield started with usual upgrades like a Kenne Bell 3.6LC supercharger, and intake and exhaust improvements. With a little nitrous thrown in the mix, the car made really good power.
However, the stock engine’s oil pump gears gave out while running down GTRs, which necessitated a redo. Progressive Racing Engines redid the short block, and the stock heads went back on with Comp Cams Stage 3 camshafts. The Kenne Bell 3.6LC was discarded in favor of the company’s big dog 4.7L supercharger, and with 28 pounds of boost the combination was good for over 1,000-rwhp.
At the 2015 Mustang Week, mechanical damage once again reared its ugly head with a broken rod. He noticed the engine wasn’t running right after a couple days into the event, and thought he had addressed the car’s issues with a new mass air meter. It appears, though, the damage was already set in stone, and during “spirited driving,” a connecting rod let go.
