Product description

Unleash the true potential of your GM Truck/SUV with Magnuson’s TVS1900 Radix Supercharger System
Available for the 2011-2013 Silverado / Sierra 6.0L 6.2L, this bolt on supercharger is designed to deliver maximum performance while retaining factory-like drivability and reliability. Generating 6 psi of boost, the Magnuson TVS1900 Hybrid Roots Style Supercharger delivers power gains of approximately 120 horsepower and 120 foot-pounds of torque at the rear wheels! But peak horsepower and torque numbers don’t tell the whole story. "Under the curve" power is significantly enhanced 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, hauling a heavy load, 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 with 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 vehicle 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 in the middle of 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.

FAQs

How does the TVS1900 Radix system improve performance on GM trucks?
The TVS1900 increases airflow to deliver strong gains in horsepower and torque. This enhances acceleration, towing capability, and overall responsiveness, making the truck feel more capable in everyday and heavy-duty use.
Is the TVS1900 a good match for 6.0L and 6.2L engines?
Yes. The TVS1900 provides an ideal balance of airflow and efficiency for these engines, delivering consistent performance while maintaining smooth drivability.
How does this system perform under load?
The system delivers strong low-end torque, allowing the truck to handle towing and hauling with greater ease. Power is available immediately, improving performance in demanding conditions.
What supercharger architecture is used in the TVS1900 system?
The system is built around Eaton’s Twin Vortices Series (TVS) 1900 rotor pack, featuring a four-lobe, high-helix design that improves air movement and reduces internal leakage. This architecture delivers highly efficient airflow, lower heat generation, and immediate boost response throughout the RPM range.
How does this system impact overall driving feel?
The added torque and power create a more responsive and capable driving experience, especially when accelerating or carrying heavy loads.
