Hellion Hellraiser Twin Turbo System – 2003–2004 Ford Mustang Mach 1 4.6L DOHC
The Hellion Hellraiser Twin Turbo System for the 2003–2004 Ford Mustang Mach 1 is one of the most powerful and versatile forced-induction solutions ever developed for the New Edge DOHC platform. Designed for extreme horsepower capability while maintaining flexibility and drivability, this system delivers unmatched performance potential for serious street and race builds.
What truly separates the Hellraiser system from other turbo kits is its ability to function either as a traditional twin turbo setup or as a compound-boost system. When paired with a Roots-style supercharger, the Hellraiser becomes the first aftermarket compound-boost solution available for the Mustang platform. In compound configuration, the turbos feed pressurized air into the supercharger, producing higher total boost, increased low-end torque, and superior average power throughout the RPM range.
Unlike belt-driven superchargers that introduce parasitic loss, the Hellraiser system uses spent exhaust energy to generate boost efficiently. This results in greater power to the tires, improved throttle response, and the ability to support power levels far beyond what single power-adder systems can achieve.
At the heart of the system are twin Precision 61mm cast-wheel journal bearing turbochargers, chosen for their proven reliability, quick spool characteristics, and strong top-end power capability. With proper fueling, tuning, and engine upgrades, the Hellraiser system is capable of supporting mild street combinations all the way to extreme high-horsepower race applications.
Hellion’s American-made stainless steel hot-side and cold-side piping ensures excellent fitment, long-term durability, and consistent performance under high boost conditions. Every component is engineered to integrate seamlessly into the Mach 1 chassis while leaving room for future upgrades and customization.
This is a true tuner system and does not include fuel system components or engine calibration, allowing builders to configure the setup around their specific performance goals. Whether remaining turbo-only or evolving into a compound-boost configuration, the Hellraiser Twin Turbo System provides unmatched flexibility and capability.
