When ProCharger developed the ultimate supercharger system for the high compression, highly-sophisticated 4.6L 4V engines, the goal was simple: maximum performance and reliability with minimal cost and maintenance. The results speak for themselves–550 RWHP to 750 RWHP on stock 4V engines.

Tuner Kits: These kits make sense for someone wanting to perform custom tuning of the car and push the envelope in performance. Will most likely be experimenting with alternative fuels such as 93 octane, race fuel, E85 fuel, and methanol supplemental fuel. In addition, possibly changing engine components like heads, headers, exhaust, and cams for the engine. No tuning or fuel components provided.
