One of the best "bangs for your buck" is our Pulley Power Package for the Gen1 MINI Cooper S. This kit includes the new Alta 15% Supercharger Pulley, Gates Supercharger Belt, and Alta Tensioner Stop. Installing our Pulley Power Package is a great way to increase your Motoring experience.
Alta 15% Supercharger Pulley
While MINI may have given the Gen1 Cooper "S" owners a literal boost over standard Coopers there is no reason to be comfortable with 163HP. One of the best ways to turn up the power is to turn up the boost with our Alta Supercharger Pulley for your Gen1 MINI Cooper S.
ALTA was the first manufacturer to design a two piece, taper fit Mini Cooper Supercharger Pulley. Today, it's the most imitated design on the market. Their latest version of the ALTA pulley has taken pulley design to the next level. Installation is easier than ever, and the results are even more fantastic.
Gates Supercharger Belt
When your Gen 1 MINI Cooper S gets into the higher miles, or you're installing a new Supercharger pulley, it's time to start thinking about replacing your belts. If you're installing a smaller supercharger pulley you will need a smaller belt to reduce the slack and allow the belt tensioner to work properly. Gates belts are used by MINI as their OEM belt supplier and trusted in racing conditions due to their high quality design.
Alta Belt Tensioner Stop
The Alta belt tensioner stop for the Gen1 MINI Cooper S is an inexpensive and easy to install part that will add peace of mind and save you money in the event of a belt failure on your MINI. This device installs around the tensioner damper and prevents the dampener from over expansion in the event of the belt breaking, potentially saving days of downtime and hundreds of dollars repair charges. Just slip the tensioner stop over the forward damper bolt and installation is complete. This is an excellent part to install whenever you change your timing belt or upgrade your supercharger/crank pulley.
Gates belt #K060535 is 1379mm and works with both a 15% or 17% pulley with stock crank pulley. The Gates belt # K060539 is 1385mm and works with the 15% or 17% supercharger pulley with a 2% crank pulley.
