Magnuson Magnum TVS2300 Supercharger Kits

Magnuson Magnum TVS2300 supercharger is designed to deliver maximum performance while retaining factory-like drivability and reliability. Generating 6 psi of boost, the Magnuson TVS2300 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. 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 derivability and fuel economy - giving you a package that delivers power without compromise.

ProCharger P-1X High Output Supercharger Systems

ProCharger P-1X high-output supercharger head units feature the robust, self-contained gearcase that is standard on most ProCharger models, but with a new aerodynamic compressor design. They create cooler-charge air temperatures and more horsepower at the same boost level and step-up ratio as their industry-standard supercharger kits (P-1SC-1 and D-1SC). This higher efficiency design is engineered to be a bolt-in replacement for both of those—they fit in the same brackets—and offers greater maximum-power potential. The compressor side of these superchargers (the volute and impeller) was redesigned with greater efficiency and less parasitic engine load in mind. This produces less heat and power needed to spin the impeller—and that adds up to more horsepower. Bolt-on some of the largest street-legal power gains available with a ProCharger P-1X high-output supercharger system. Additional features: * 10-15 flywheel horsepower gain on otherwise stock, modern V8 automotive engines at the same boost level and pulley size (versus P-1SC-1 models) * Larger gains possible at the same boost level with built and modified motors * 875-plus horsepower-capable * Designed for today's high-flowing modern V8 engines producing 300-plus naturally-aspirated horsepower * Available as optional upgrade with ProCharger systems and tuner kits * Highly-durable, high-horsepower designs with a compact, state-of-the-art 9.0 in. housing/volute * Available with standard or reduced-noise level * Slightly larger volutes than P-1SC-1/D-1SC models
