Product Description

The ALTA performance pulley for your supercharged Mini Cooper S / JCW will increase your horsepower by an additional 20 WHP!  

It installs easily and no modifications to the engine or ECU are required.  Talk about easy!

It's a two piece, taper fit for your Mini Cooper S supercharger.  Since releasing this product in 2002, it has often been imitated but never duplicated.  This is the most recent version of ALTA's famous pulley and is the best on the market.  

Geeky Stuff

This supercharger pulley featured a stainless steel supercharger shaft coupler with installation site aperture and direct torque technology.  With its very light aluminum body, the pulley decreases rotational inertia and overall weight to make your engine work easier and more efficiently.  The kit also includes a decorative end faceplate for a clean installation.


You will notice the difference of power immediately after installation; it's just that good!



ALTA Pulleys are offered in two sizes: 15 and 17% reductions. The 15% pulley is the market standard and produces smooth, safe power increases. For those seeking a bit more power, the 17% is the ideal choice! Builds boost at lower RPM's giving you even more power down low where you need it, combined with another 1.5 lbs at redline gives you the extra HP to conquer even the toughest challenge!



Simply lift the engine, remove stock pulley using the ALTA Version 2.0 pulley puller and slide your new ALTA Performance Version 2.0 pulley directly onto the supercharger shaft. Tighten the bolts, lower the engine back into place and your done! (Yes this has been simplified a bit, but click above and download a set of our highly detailed instructions. See below for the needed special puller.) There is no longer reason to remove the entire supercharger to pull off and press on a pulley.
