Magna Charger’s new MP 2300 supercharger technology is the same used for the new ZR1 Corvette. The four-lobe rotor features a high-twist 160? helix that has improved efficiency (less power to drive), cooler discharge temperatures and is much quieter. Additional efficiency is the result of the unique bypass valve that reduces parasitic drag during normal driving. The Magna Charger also interfaces seamlessly with the GM Active Fuel Management system (some models) that cuts the engine to four cylinders at light throttle. The Magna Charger system, with its Roots design, provides substantial power increase: 150 bhp with stock LS3. High manifold pressure produced at low engine RPM provides significantly more low end and mid-range torque compared to centrifugal superchargers. Magnuson's unique intercooler design, built into the intake manifold base (patent pending), lowers charge air temperature up to 100F to increase power.
