How to change your supercharger pulley
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
If you have a pre-2022 supercharger, head to the video dedicated to the old style pulleys and pulley adapter.
How to change outlet direction of your supercharger
Is your supercharger blowing the wrong way? Or perhaps you need to remove the compressor housing to weld on a tight bend or clamp connectors?
We’ve got you covered in this simple instructional video – it’s only 6 bolts, but you will need to remove the supercharger from its bracket.
As always, take care to not damage the compressor wheel!
