Show original supplier description
The Hellion Turbo Street Sleeper® Hidden Twin Turbo System is engineered for the 2020+ Ford Mustang Shelby GT500, aiming to surpass the power capabilities of any supercharger with adjustable horsepower exceeding 1400+ HP. This system offers a robust and proven twin-turbo alternative to the factory supercharger, designed with a focus on "sleeper" image and maximum performance. The kit features Hellion 64/66R twin turbos, a large 6" vertical flow core intercooler, and American-made stainless steel piping backed by a lifetime warranty. It includes Twin Turbosmart Comp-Gate 40 wastegates for precise boost control, Twin Turbosmart VEE port bypass valves, heavy-duty silicone hoses, stainless steel T-bolt clamps, high-flow K&N air filters, and an exclusive Hellion oiling system for the turbochargers. All necessary hardware for installation is included, along with a complete instruction set. Installation requires the removal of the factory supercharger and the use of a factory or factory-style intake manifold (e.g., Holley, TTR, Plazmaman, or custom). The system is built for daily driving in all weather conditions, providing protection against water and debris. Note: Hellion's products are sold for competition vehicles only and are not legal for sale or installation in California. All performance modifications are at the customer's risk. This system is specifically designed for the 2020+ Ford Mustang Shelby GT500. It is also compatible with the 2018-2023 Ford Mustang and 2015-2017 Ford Mustang models.
