Hellion Turbo is back in the spotlight, with FordMuscle featuring a twin-turbo Shelby GT500 that proves just how much potential the platform has when equipped with Hellion power.
The feature follows Ken Bjønnes of Palm Beach Dyno and his Shelby GT500, known as “Overkill,” as the car returns with a new engine combination and Hellion’s Twin-Turbo Sleeper system. After previously pushing the factory 5.2L Predator engine to its limits, the GT500 was upgraded with a built long-block, high-flow cylinder heads, a Plazmaman intake manifold, and a Hellion twin-turbo system designed to take the car to the next level.
At the center of the build is Hellion’s Street Sleeper® approach: serious twin-turbo performance without turning the engine bay into an obvious turbo showcase. The hidden layout keeps the car clean and deceptive while delivering the efficiency, adjustability, and horsepower potential that only a properly engineered twin-turbo system can provide.
For 2020+ Shelby GT500 owners looking to make the same move, Hellion offers its Street Sleeper® Hidden Twin Turbo System. This system removes the factory supercharger and replaces it with Hellion 64/66R billet wheel ball-bearing turbos, 4-into-1 headers, a large 6-inch vertical-flow intercooler, American-made stainless-steel piping, twin Turbosmart Comp-Gate 40 wastegates, twin Turbosmart VEE Port bypass valves, heavy-duty silicone hoses, stainless T-bolt clamps, high-flow K&N filters, and Hellion’s proven turbo oiling system.
The result is a true bolt-on GT500 twin-turbo system engineered for massive power, clean fitment, and daily-drivable performance. No factory sheet metal modification is required, and the system is capable of supporting 1,400+ horsepower for owners ready to push beyond the limits of the factory supercharger.
Ford’s Shelby GT500 is already one of the most capable modern Mustangs ever built, but Hellion’s Street Sleeper system gives it an entirely new ceiling. For drivers who want hidden horsepower, turbocharged efficiency, and the ability to surprise just about anything in the other lane, this is the ultimate GT500 upgrade.
