Adding a Magnuson Supercharger to your H2 Hummer is an efficient way to unleash the true potential of your engine
Available for the 2008-2009 Hummer H2 6.2L, this bolt on TVS Supercharger Kit is designed to deliver maximum performance while retaining Hummer-like drivability and reliability. Pumping out 6 pounds of boost, you can expect the TVS1900 Hybrid Roots Style Supercharger to deliver power gains of around 120 horsepower and 120 foot-pounds of torque at the rear wheels. But peak horsepower and torque numbers cannot tell the whole story. "Under the curve" power is significantly improved delivering near instantaneous boost and torque upon demand that really pins you back in your seat. So whether you are roaring down the drag strip, towing a trailer, forging a trail through the wilderness, or taking the family cross-country our TVS1900 supercharger will give you the torque and horsepower you need whenever you want it.

Inside of the supercharger manifold, a large liquid-to-air intercooler keeps your Intake Air Temperatures in check and provides consistent and repeatable performance. Combine that with the front-mounted heat exchanger, electric water pump, and intercooler coolant reservoir and you have a supercharger system that has IATs that are typically only 20-40 degrees (Fahrenheit) over the ambient temperature.

Maximizing your efficiency during cruising is the job of the supercharger’s integrated bypass valve. This vacuum operated system allows air to bypass the supercharger and the rotors to “free-spin" under light engine loads. During this situation the parasitic loss of the supercharger system is essentially negated taking less than one-third of a horsepower to turn the rotors. This bypass valve also allows your supercharged Hummer H2 to maintain stock-like drivability and fuel economy - giving you a package that delivers power without compromise.

Down to the smallest part, our Magnuson line of bolt-on supercharger systems are engineered as a complete package. The supercharger, supercharger intake manifold, inlet, pulley, fuel injectors, fuel rails, front & rear fuel crossovers, and intercooler come pre-assembled to make installation simple and easy while the accessory box is organized into individual sub-assemblies to help ensure that you don’t lose track of parts during your install. All of the hardware needed for a full and complete install is also included so you won’t be running to the local parts store in the middle of your installation. In addition, our full color, step-by-step Installation Manuals will walk you through the install process with exacting attention to detail

Magnuson’s TVS1900 supercharger utilizes EATON’s latest 6th Generation supercharger rotor technology found in such industry leading performance vehicles as the Corvette ZR-1, the Cadillac CTS-V, and the Mustang GT500. These Twin Vortices Series Superchargers feature a pair of four-lobe, high-helix rotors with 160-degrees of overall twist that are housed in Magnuson’s patented high-flow housing. This highly efficient package requires less power to drive, delivers cooler discharge temperatures, and is much quieter than many of its competitors. These superchargers are all manufactured in our TS16949 certified facility – the highest ISO OEM quality certification standard in the market. Designed to be nearly maintenance free so you won’t have to worry about anything once it is installed.
