Supercharger Pulley
Scratch and Dent?
Occasionally, we get new parts or returns that have cosmetic blemishes that do not affect the functionality of the part. Rather than toss them in the scrap bin, we offer the parts for sale at a deeply discounted price. In many cases, the location of the blemish prevents it from even being seen once the part is installed. Like all of our products, we still guarantee it to be the correct fit and to work properly and will offer to exchange components should anything need adjustment. Please note that we do not issue refunds for scratch and dent parts.

Original Design, still made in the USA
CravenSpeed designed and championed the 2 piece supercharger pulley in 2005. Our work has been copied hundreds of times, but never matched. The same expert machinists have been making our pulleys for years and ensuring that each one meets our high standards of quality. Smooth, form fitting teeth on your pulley take longer to machine but are worth the extra time. Our pulleys will neither eat nor throw your belt. You can be confident your belt will last long, and run quietly. We do recommend using a slightly smaller belt with these reduction pulleys, we offer the Gates FleetRunner belt. Refer to the guide if you aren't sure whether you need a belt or not.
15% or 17% ??
If both sizes are safe for your supercharger, then which one should you choose? The supercharger is only creating boost under acceleration, on a normal or even a spirited drive this is only occasional. However, at the track or an autocross event acceleration is sustained and frequent. If you use your MINI for these types of events it is better to use the 15% reduction. This is because the 17% pulley causes the supercharger to heat more rapidly and the warm air begins to negate the positive effects of the extra PSI earlier in the band.
Fitment
This pulley will work on all supercharged MINI models. If you have a JCW, that model starts with a smaller pulley than the standard ‘S’ model but both of these options are still slightly smaller than that one. Although this two part pulley is self-centering to help ease installation you may still want to check our dealer finder for a CravenSpeed Authorized Installer near you. If you plan on wrenching on your own, make sure you have a pulley puller designed to remove the MINI's press-fit OEM pulley. Our quick puller allows you to remove the OEM pulley without removing the tensioner and is available for either the S or JCW sized pulleys.
