This pulley is intended for professional installation only. The upper portion of the supercharger must be disassembled so the supercharger snout can be removed.  Installation instructions are not provided.

 When the supercharger pulley is changed, the PCM calibration requires revisions to accommodate the increased level of airflow.  However, some installers have used the 3.10" and 3.20" sizes with excellent results, without revising the PCM tune.  

We always suggest looking at the tune after the pulley change to confirm proper air/fuel and timing calibrations, in the interest of maximizing reliability and longevity.

User assumes all risks.  Installation of this pulley may affect your warranty.
