Description

The Hellion Sleeper Hidden Twin 64/66 Turbo System is a high-performance upgrade designed to replace the factory supercharger on the Mustang Shelby GT500, offering a bolt-on solution capable of generating over 1400 horsepower. This system provides tunable power potential, delivering strong and reliable performance while maintaining a stealthy sleeper appearance. Constructed with American-made stainless steel piping that features a lifetime warranty, this system includes a large 6-inch vertical flow core intercooler and billet wheel ball bearing turbos. The kit comes with all necessary bolts, nuts, and hardware for installation, along with a complete instruction set. It is important to note that this kit is intended for competition vehicles only and is not legal for sale or use on licensed vehicles in California due to not meeting CARB compliance. Additionally, programming is not included with this system, and mechanical expertise or professional installation is required. This system is specifically engineered to fit 2020 through 2022 Mustang Shelby GT500 models, tailored for factory fitment.
