Unleash the true potential of your GM Truck/SUV with Magnuson’s TVS1900 Radix Supercharger System
Available for the 2007.5-2010 Chevrolet Silverado / GMC Sierra 1500 4.8L / 5.3L, 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.

What our customers are saying
"When I changed from a Class 1 trailer to a Class 3 trailer, the 5.3 just could not easily pull the load. The Yukon was in 3rd gear at 3K rpm at 70mph on flat road and any incline meant that it was downshifting to 2nd gear at about 4,400 rpm and struggling to maintain speed. This was a recipe for engine disaster. I chose Magnuson for a supercharger because it was the only maker who had a program for towing AND I love the fact that the OEM cold air intake could just be plugged in with no mod's needed. Now, I cruise at 1,800 rpm in 4th gear at 70 mph on flat roads and go up inclines for quite a distance before the transmission shifts to 3rd gear at 3k rpm and I back off the throttle as it will begin accelerating up the hill. I also noticed an increase in gas mileage as I am operating at a much lower rpm. This has also helped my water and transmission oil temperatures to go down noticeably. I plan on keeping this Yukon for many years of towing." -- Jim M, GA

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 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. Designed to be nearly maintenance free so you won’t have to worry about anything once it is installed.
