6-Rib Supercharger Pulley for Vortech Superchargers.
Vortech 6-Rib Supercharger Pulleys are machined from 6061 T-6, hard anodized aluminum with the proper profile to maximize surface contact area for precise fit. Each pulley is built to SAE standards.
When installing a new blower belt, don't go wide open throttle for the first hour as the belt needs to break in. Once the belt is broken in you will find that it has stretched, and it will then need to be tightened back down. Do this before going wide open throttle with a new belt, as once a belt slips it is more prone to slippage.
