Why have OEM manufacturers such as Ford, GM, Jaguar and Mercedes Benz turned to supercharging? Instant, reliable power! Imagine your Miata passing simply by rolling on the throttle…no downshifting. Climb a hill in 5th gear instead of 3rd. Leave a stoplight completely sideways-burning rubber. It’s all possible with the Jackson Racing Supercharger system.

The core of the Miata supercharger system is a roots type Eaton M45 supercharger; Utilizing the same patented technology that the big OE manufacturers use in their supercharged vehicles. By incorporating a vacuum bypass system, air is directed around the supercharger while cruising; Excellent reliability and fuel economy are retained. When you need power, simply stand on the throttle and the bypass valve closes, instantly pressurizing your engine’s intake system.  

The Supercharger is only one part of the equation. To achieve a smooth rush of power and excellent driveability, proper tuning is essential. All 94-05 Jackson Racing Supercharger Systems use PowerCard as their fuel management solution. PowerCard is a Load-based tuning solution that combines the latest in microprocessor technology and self-diagnostics. Under normal conditions PowerCard waits patiently off-line, but Accelerate aggressively and PowerCard instantly steps up the fuel necessary for boost. Using an Ultra-fast microprocessor that reacts just as quickly as your factory ECM, your Miata drives just as Mazda intended, whether in Boost or not.
