Product Description

Go Faster -- When you put a smaller pulley on your MINI's supercharger, then the crank spins it faster. When the supercharger pulley spins fast, it creates more pressure (psi). When the supercharger has more pressure, the engine gets more boost. More boost = More Speed

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, a NAPA 060539 or similar.
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.
Stainless Steel is what we currently offer. There are Red Pulleys in the Speed Pulley Set (Supercharger, Lightened Crank & Overdrive Alternator Pulley). If you are looking for a little something extra, try the Speed Pulley Set (sold in this section of website). You'll get the benefits described above plus some added boost.

Pulley Puller
Our cost-effective pulley puller will help you get your new MINI supercharger pulley on faster. With our tool, you will be able to remove the stock press fit pulley safely, without removing the tensioner. Time is money and this puller will save you both.
