Inside Information
Want to build something similar to the engine we tested on the dyno? Then check out the specs below. While this mule was sporting big inches, the kit will work well on smaller-displacement motors.

On the dyno, eight individual O2 sensors (four on each header) were used to measure air/fuel ratio in all four cylinders. This was done to monitor fuel distribution, and on this test we found air/fuel ratios from 11.7- to 12.2:1. | 
The supercharger's aluminum housing has been redesigned to accept the special high-helix rotors. | 
At the heart of this extruded-aluminum unit are the APC (abraidable powdercoated) rotors featuring an involuted shape to provide excellent sealing, improved efficiency, and more power. |
