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. CravenSpeed 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. 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 pulley. 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. Will it work on my car? This pulley kit will work on all supercharged MINI models including the JCW which has a 12% reduction pulley on the supercharger from the factory.
