15% Supercharger Pulley - WMW

15% Supercharger Pulley - WMW 
The Way Motor Works custom 15% MINI Cooper Supercharger pulley for R53 MINI Cooper S increases the rotating speed of the supercharger by reducing the diameter of the pulley driving your supercharger. Our design has the following features not found on other pulleys:
  • A 2 piece collet style design utilizing 4 bolts to lock the pulley to the supercharger shaft.
  • Taller lips on the front and back to ensure the belt stays put while driving and for easier belt installation.
  • Four jack bolt holes to allow for reduced weight and to ensure proper installation.
  • Made in the USA
The WMW supercharger pulley is CNC machined from the highest quality stainless steel to exacting tolerances for perfect balance. The 15% size reduction pulley is widely accepted as the optimum balance between performance gains and engine longevity. For the R53 Mini Cooper S this is definitely the best HP for your buck modification!  Horsepower gains as much as 20 hp have been seen by adding this.

If you have a 1st generation Cooper S (R53), installing a 15% reduction pulley is widely regarded as the best performance enhancement one can do for your MINI. You can really feel the difference in power output. I highly recommend this product. And if you have Way install it for you, you can rest assured that the install is going to be correct. Thanks, Way!

I bought my wife a package. I got her the pulley kit, the Milltek exhaust, the cold air induction and a dirty tune. The guys at Way Motor Works are top notch and made my Mini Cooper come alive. It is a blast to drive. Well worth the money! Thanks guys!

Got the pulley package deal from WAY, installed myself using the information provided on his site and took me less than 5hours.
My car is a beast now ,I am not a racer but I like the extra boost and of course the fast sprint , in no time my speedometer id at 100.
Great buy from Way, very pleased with the service,I am looking forward to do business with him.Keep up the great work people from WMW.

I met Way for the first time in 2011 at the MOTD event where the team installed a JCW cold air intake for me. Prior to the 2012 event I outlined several planned mods I was considering. On Way's suggestion I went with the 15% pulley "kit". I had the kit installed on Tuesday, which gave me some "Dragon" driving time before Way did the ECU performance tune. All I can say is WOW!! The combination of those two has made my 2004 R53 (MCS) more fun to drive than ever. Bottom line: Quicker/Faster - Increased throttle response, increased low-end torque, and extended rev limit is especially noticed in the lower gears. This is a MUST HAVE mod!

This really should be your first mod for your r53. It should've came this way from the factory. Its pretty much mandatory to have. If you don't buy this one...be prepared for other r53 owners to look at you strangely, ha!
