Product Description


Unleash the true potential of your LS2 powered GTO with Magnuson's MP112 Supercharger Kit. This kit, designed for the 2005 to 2006 Pontiac GTO with the 6.0L LS2 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 GTO'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 GTO 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.

great upgrade from stock

It was an excellent improvement in HP for my stock GTO. Although, I now have belt slippage. But that can be easily dealt with by either buying an upgrade adjustable tensioner or different size pulley. ;)
Outstanding .. This one ROCKS with power..

Outstanding supercharger kit, looks awesome, performs even better than expected.. Comes complete as they say, needs nothing but installed.. Expensive, but worth it for quality..The GOAT is running WILD now..
