    More Horsepower! The stock 1996 to 2004 4.6L V8 Mustangs came with respectable Horsepower and Torque from the factory, but after installing a Hellion Twin Turbo Kit you will be planting a tire shredding 400 to 1,200 Horsepower to the pavement (depending on custom tuning and fuel upgrades).

    Tuner Kit. The Hellion Mustang Twin Turbo Tuner Kit comes with two Turbonetics 61mm Turbos and all the required parts and hardware needed to upgrade your mild manner pony to a wild snarling beast. Custom dyno tuning is required for operation.

    Compound Boost. This unique Twin Turbo system was engineered to work with or without a roots style supercharger. If installed with a roots style supercharger this system becomes a "compound boost" setup to produce even more power and torque.

    Retains A/C. The Hellion Turbocharger system is designed to retain the factory air conditioning, A/C lines, and accessories for complete driver comfort.

    Application. This Hellion Twin Turbo Kit is specifically designed for use on the 1996 to 2004 4.6L V8 Mustangs including the GT, Bullitt, Mach 1 and SVT Cobra models.

    5 Top Rated Questions

    Can this be installed withe the stock "K" member, or will modifications need to be made?

    • Mack The Hellion Twin Turbo - Tuner Kit for a 1996 - 2004 Mustang. This kit comes with a UPR front suspension set-up. The Maximum Motorsport K-member, A-arms, and coil overs are an optional kit. This way no mods need to be made. Duke7

    Boost/HP What is the lowest amount of boost these turbos produce and what's the hp gain? And what's the highest boost/hp gain possible? My engine sits back and there is a nice gap from the belt to the radiator which would hopefully fit the twin turbos nicely.

    • LaserRed2StangGT The Hellion Twin Turbo - Tuner Kit , for a 1996-2004 has a low boost of 5 and a high boost of 30. Horse power boost will vary upon engine components. Hellion Twin Turbos mount on each side of the front bumper. Duke7

    auto I have a auto trans and would like to know if these would work with it or no and if so what mods would i need to do to make them work

    What is the difference between this "tuner kit" and the "complete kit." How do I know which one I need?

    • The complete kit comes with every needed for installation. The Hellion Twin Turbo Tuner Kit, Item 42601, does not come with fueling components and will need a custom dyno tune. The Hellion Single Turbo which is complete, Item 42604, comes with injectors and a base map tune. The kit that would be best for you would really depend on what you are looking to achieve out of the turbo kit. If you would like to give us a call or send an email or chat, we would be more than happy to discuss which kit would be best for you and your Mustang.
