ROTREX Superchargers - Pulley Change Procedure

In need of more boost? You're going to need a smaller pulley. Our 6 bolt pulley design makes it easier than ever to change pulley size - follow along in this video to see how it's done.
Our pulleys are available in sizes from Ø70-110mm in 5mm increments. Make sure that you don't over-speed your supercharger - if you're in doubt, use the minimum pulley size calculator, found here: www.rotrex.com/calculators
If you have a pre-2022 supercharger, head to the video dedicated to the old style pulleys and pulley adapter.
