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.
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.
Fitment
This pulley will work on all supercharged MINI models except the JCW which already has a similarly reduced size pulley on the supercharger. 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.

Needed a special tool to remove oem pulley, easy install with 2 piece pulley. Belt is very tight length wise. Had to remove 2 of the ac compressor bolts and tilt it to install belt.
