Product Description


Unleash the true potential of your L76 powered G8 GT with Magnuson's MP1900 TVS Supercharger Kit. This kit, designed for the 2008 to 2009 Pontiac G8 GT with the 6.0L L76 engine, is capable of making approximately 120 horsepower and 120 foot-pounds of torque at the real wheels with only 6 psi of boost. The "under the curve" power is also significantly enhanced, delivering near instantaneous boost and torque response. This supercharger is designed to deliver maximum performance while retaining the G8 GT's drivability and reliability.

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

The supercharger's integrated bypass valve maximizes your efficiency during cruising. The vacuum operated system allows air to bypass the supercharger and the rotors to "free-spin" under the 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 G8 GT to maintain it's stock-like drivability and fuel economy which gives you a package that delivers power without compromise.

The MagnaCharger line of bolt-on supercharger systems are engineered as a complete package. All parts come pre-assembled to make installation simple and easy. The accessory box is organized into individual sub-assemblies to ensure you don't lose track of your parts during installation. All hardware and installation manuals are included.

Magnuson's MP1900 TVS supercharger utilizes EATON's 6th Generation supercharger rotor technology and features a pair of four-lobe, high-helixed rotors with 160-degrees of overall twist, housed in Magnuson's patented high-flow housing. This creates a highly efficient package that requires less power to drive, delivers cooler discharge temperatures and is much quieter than many competitors. These superchargers are manufactured in Magnuson's TS16949 certified facilities - the highest ISO OEM quality certification standard in the market. The supercharger is built to last and backed by a 3-year, 36,000 mile warranty.
