Vortech V-3 Supercharger System with Intercooler

The Stillen Supercharger System is a comprehensive, turn-key bolt-on kit engineered to significantly enhance the performance of your 2009-2013 Infiniti G37 Sedan and 2015 Q40. This system features a satin-finish Vortech V-3 supercharger unit, known for its quiet operation and self-contained oiling system. It incorporates an air-to-water intercooler to efficiently chill the air charge before it enters the engine, promoting denser air for greater power output. This supercharger system is CARB exempt (E.O. #D-436-20), ensuring 50-state legal emissions compliance. It is compatible with both RWD and AWD models. The estimated horsepower output ranges from 480-520 HP at the flywheel, with typical wheel horsepower around 400 WHP. Torque is substantially increased for superior response, while maintaining stock-like fuel economy when cruising at lower RPMs. The kit includes larger injectors and a new fuel pump to support the increased airflow, managed by a remapped factory ECU. A one-year development process focused on precise engineering and innovative problem-solving, particularly in optimizing the ECU fuel management settings. The main supercharger unit comes pre-assembled to laser-cut billet aluminum mounting brackets. Typical installation time for a competent shop is around 12 hours. The system also includes provisions to work with existing coolers (oil, transmission, power steering) due to the Nissan VQ37 engine's tendency towards high oil temperatures. A limited lifetime warranty is provided for the supercharger kit, and a 3-year/36,000-mile powertrain warranty is available.
