The LQ9 engine is part of Chevy's potent Gen III powerplants. These engines make 360 hp and 380 lb-ft of torque. They are incredibly receptive to modifications too, so the power only goes up from there.
The Magnacharger supercharger replaces the factory intake manifold and comes complete with all necessary fuel system upgrades, electronics, and even an integrated water-to-air intercooler to keep the intake charge cool and dense. The system ups power to approximately 475 hp and 500 lb-ft of torque with most of the power coming right off idle.
