Safe for Extended Use

CravenSpeed's supercharger pulleys are machined to a specific reduction of the original equipment on your MINI's supercharger. It is widely accepted that these sizes are safe amount of reduction on this particular supercharger. 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 guide if you aren't sure whether you need a belt or not.
Which Gates belt do I need? Stock Crank Pulley 2% Oversized Pulley

15% SC Pulley #060535 Stock Belt
17% SC Pulley #060535 #060535

15% or 17% ??

If both sizes are safe for the supercharger 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.


This pulley will work on all supercharged MINI models except the JCW which already has a similarly reduced size pulley on the supercharger. 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 do on wrenching on your own, make sure you have a 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.

    The Mini S had power but with the 17% reducer it now has more get up and go. Best mod for the buck. The car drives the same with the nice supercharger whine until you floor it and then it pushes you back in the seat.

    I just installed this pulley on Monday, and I love it. I'm a tech so install was pretty easy, and the notice in power was immediate. I got the 15% and am super happy. Would definitely recommend this pulley to anyone.

    Very easy install and great performance boost. 5 Star Review

    I was a little worried about doing the pulley swap myself but the Craven Speed pulley along with the pulley puller made the job very easy.

    I was very happy with the detail in the pulley's construction and the ease of installation with the 4 bolts.

    The pulley has been on for a couple weeks now and I am loving the extra boost.

    Over all I am very satisfied with this product.
