Hellion Hellraiser Twin Turbo System – 1999–2001 Ford Mustang Cobra 4.6L DOHC
The Hellion Hellraiser Twin Turbo System for the 1999–2001 Ford Mustang Cobra is one of the most powerful and versatile forced-induction solutions ever engineered for the New Edge DOHC platform. Designed to support extreme horsepower while maintaining flexibility and drivability, this system delivers unmatched performance potential for serious street and race builds.
What separates the Hellraiser system from every other turbo kit on the market is its ability to operate either as a traditional twin turbo system or as a compound-boost setup. When paired with a Roots-style supercharger, the Hellraiser becomes the first aftermarket compound-boost solution available for the Mustang. In this configuration, the turbos feed pressurized air into the supercharger, creating higher total boost, stronger midrange torque, and superior average power across the RPM range.
Unlike belt-driven superchargers that introduce parasitic loss, the Hellraiser uses spent exhaust energy to generate boost efficiently. The result is a system capable of producing more horsepower, more torque, and more usable power than any single power-adder solution available for the 4.6L Cobra.
At the core of the system are twin Precision 61mm cast-wheel journal bearing turbochargers, selected for their proven reliability, fast spool characteristics, and strong top-end horsepower 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 builds.
Hellion’s American-made stainless steel hot-side and cold-side piping ensures precise fitment, long-term durability, and consistent performance under high boost. Every component is engineered to integrate seamlessly into the New Edge Cobra 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 tailor the setup to their exact performance goals. Whether your build remains turbo-only or evolves into a compound-boost monster, the Hellraiser Twin Turbo System offers unmatched flexibility and capability.
