Vortech V-3 Si Supercharger System w/ Intercooler & UpRev Tuning

The Stillen Supercharger System is a comprehensive, turn-key solution engineered to dramatically enhance the performance of your 3.7L VQ37HR engine. Designed as a direct bolt-on, this kit leverages a satin Vortech V-3 supercharger unit and an advanced air/water intercooler system to deliver substantial power gains. With an estimated output of 480-520 horsepower at the flywheel and approximately 400 wheel horsepower (WHP), it provides a significant boost in performance suitable for daily driving, spirited canyon runs, and track days. This system features a front-mounted, compact heat exchanger that efficiently cools the air charge without impeding airflow to other essential coolers like the radiator and engine oil cooler. The intercooler is integrated directly into the redesigned intake manifold, allowing for immediate cooling of the air before it enters the engine. The V-3 supercharger unit itself boasts a self-contained oiling system and a quiet V-belt design, offering additional boost potential for future upgrades. The complete kit includes larger fuel injectors and a new fuel pump to complement the remapped factory ECU, ensuring optimal fuel delivery and performance. Included with the kit is tuning via UpRev software, with options for a cable and data logging for DIY or remote installations, or without a cable for tuners who already possess the necessary equipment. The system is CARB exempt (E.O. #D-436-20) and is 50-state legal. Installation is designed to be straightforward, with much of the assembly completed at Stillen before shipping, and typical installation time for a competent shop is estimated at 12 hours. A 3-year/36,000-mile powertrain warranty is also available.
