Hellion Street Sleeper® Hidden Twin Turbo System (HT-1617GT350-SS) - 2016-2020 Shelby GT350

For Shelby GT350 owners who demand extreme horsepower without sacrificing the factory appearance, the Hellion Street Sleeper® Hidden Twin Turbo System is the ultimate solution. This system delivers record-setting power while keeping the engine bay and exterior deceptively stock, making it the most advanced sleeper-style power adder ever developed for the GT350 platform.

Hellion Turbo has been leading turbocharging innovation since 2004, producing some of the fastest and most reliable forced-induction systems in the world. With the Street Sleeper®, Hellion applies over two decades of experience to the high-revving 5.2L Voodoo engine, creating a twin turbo system that blends brutal performance with unmatched stealth.

Unlike top-mount systems that put everything on display, the Street Sleeper® places the turbochargers in a hidden location, preserving a near-OEM appearance while unlocking massive power potential. Boost is fully adjustable from approximately 5 to 40 psi, supporting power levels from around 600 horsepower to well over 2,000 horsepower depending on turbo selection and supporting modifications. This is the most powerful system available for a Mustang-based platform—no belt-driven supercharger can come close to its efficiency or scalability.

By utilizing spent exhaust energy instead of a parasitic belt drive, the Hellion twin turbo system delivers more usable power directly to the rear wheels. The result is stronger acceleration, higher trap speeds, and power delivery that continues to grow as your build evolves. It’s no surprise that many owners transition to Hellion systems after reaching the limits of other power adders.

Engineered as a true bolt-on solution, this system requires no oil pan tapping and no cutting or modification of factory sheet metal. Most installations can be completed in under a day, making it one of the cleanest and most refined high-horsepower upgrades available for the Shelby GT350. While the base Street Sleeper® system includes entry-level 62mm turbos, Hellion offers extensive upgrade paths including larger turbochargers, fuel system enhancements, and optional blackout packages for maximum stealth.
