No other modification offers the kind of bang for the buck that a 15% pulley does. Simply changing to a 15% smaller pulley on your supercharger instantly produces 3-4 more PSI, pushing more air and fuel into the engine resulting in a typical 15-20HP gain. Racers are always looking for places to reduce weight, and especially rotational mass. No other manufacturer took the time to create a light weight stainless steel pulley, so we decided to make our own.

Instructions and Kit details:
Included with every kit are installation instructions with lots of pictures to assist you or whoever you might have doing the work. Also we recommend a set of cooler running spark plugs while installing the 15% pulley. These cooler spark plugs will add another couple horsepower, but more importantly they help prevent pre-detonation that might occur from higher boost temperatures. The spark plugs are inexpensive insurance for your MINI.

POWER
No other modification offers the kind of bang for the buck that a 15% pulley does. Simply changing to a 15% smaller pulley on your supercharger instantly produces 3-4 more PSI, pushing more air and fuel into the engine resulting in a typical 15-20HP gain. Make stock MINI’s disappear in your rearview mirror with the extra horsepower and torque your engine will be turning out. For years MINI Cooper S tuners and owners of the JCW MINI’s have known about the 15% pulley, and it has been shown to be the ideal size for street and track. Add a DDM intake or exhaust along with your pulley and you will have even bigger power gains.
PULLEY CONSTRUCTION
A taper bore fit design found in the QD design pulley allows for easy installation with no chance of pulley misalignment found with some other pulleys. Also the DDMWorks pulley is a self-aligning pulley design, which ensures 100% accuracy during pulley installation, ensuring you of no thrown belts from improper installation. Lastly the all stainless steel construction ensures you of a lifetime of corrosion free performance, and the 5 high quality grade 12.9 stainless steel bolts ensure a secure bond between the pulley and hub.
PULLEY WEIGHT. (DDMWorks LWP real advantage) Racers are always looking for places to reduce weight, and especially rotational mass. No other manufacturer took the time to create a light weight stainless steel pulley, so we decided to make our own. Extra effort and time was taken to reduce the weight of the pulley as much as possible without compromising strength. The unique slots CNC milled into the pulley and the careful control of design helped to create the lightest of all stainless pulleys on the market, 20% lighter, in fact, than most other competitor’s pulleys. Some may say that this weight reduction doesn’t matter and is insignificant; however, we say every pound does matter when you are racing. Reduction in rotational mass allows your engine to spin up faster than the other pulleys and also makes it easier to rev match when shifting gears. Small increases in power add up to big increases in power, and that can be the winning difference.
