Hellion Hellraiser Twin Turbo System (HT-9698GT-TT) – 1996–1998 Ford Mustang GT 4.6L

The Hellion Hellraiser Twin Turbo System for the 1996–1998 Ford Mustang GT is one of the most innovative forced-induction systems ever engineered for the SN95 platform. Designed to deliver unmatched versatility, scalability, and outright power potential, this system gives Mustang owners multiple paths to extreme performance—whether running naturally aspirated, turbo-only, or full compound boost.

Unlike traditional turbo kits, the Hellraiser system was engineered to function with or without a Roots-style supercharger installed. With the supercharger removed, the system operates as a conventional twin turbo setup. Leave the blower in place, and the Hellraiser becomes a true compound-boost system—the first of its kind in the Mustang aftermarket—combining turbo efficiency with instant supercharger response.

This unique architecture allows the engine to produce more average power, greater low-end torque, and higher total boost levels than any single power-adder system available for the 4.6L 2V platform. Whether your goal is a responsive street car or a full race build, the Hellraiser delivers performance that simply cannot be matched by superchargers or single turbo kits alone.

At its core, the system features twin Precision 61mm cast-wheel journal bearing turbochargers, sized to provide excellent spool characteristics while supporting serious horsepower when paired with proper fuel and engine upgrades. Hellion’s proven stainless steel hot-side and cold-side piping ensures durability, precise fitment, and consistent performance under high boost.

This is a true tuner system and does not include fuel system components or engine management calibration, allowing builders to select injectors, pumps, and tuning solutions tailored to their exact power goals. From mild street builds to extreme compound-boost setups, the Hellraiser Twin Turbo System offers flexibility that no other system in this era can match.

Hellion’s engineering focus extends to chassis compatibility as well. This system was designed around a tubular K-member configuration to ensure proper turbo placement, exhaust routing, and suspension geometry. When installed as intended, the result is a clean, serviceable, and extremely powerful turbo system that transforms the driving experience of the SN95 Mustang.
