* Supercharged horsepower and torque data shown is a calculated estimate based on percentage increases from actual rear wheel hp/tq measurements. Higher boost and power levels are available for modified engines.

Complete systems are not approved for 2005 model year vehicles at this time.

Smog Certification In Process

These systems have not yet been approved by the California Air Resources Board. 50-State emissions certification is planned. Currently these systems are legal in California only for racing vehicles which may never be used upon a highway (off-road use only).
