Rogue Engineering has developed a power pulley kit that reduces the drag on specific pulleys while allowing others to remain at their same efficiency. This allows for perfect operation in daily driven vehicles without a hiccup or stutter. However, when the demand for power is requested, the power pulley kit allows for the freed power to become apparent.  The term "power" pulley is a bit of a misnomer. Underdrive pulleys actually free up power by reducing the drag caused by the accessories.  These pulleys are based off a calculated percentage from factory dimensions, so that particular component speeds are safely reduced without affecting their true purpose.

Rogue Engineering Power Pullies are CNC machined from 6061-T6, heat treated aluminum and specially coated with a MIL-A-8625 Type III hard coat anodize finish. This kind of anodizing is not to be confused with a Type II cosmetic anodize finish (typical colors such as red, blue, silver, green, etc.). The hard coat anodize finish actually builds a small surface layer on top of the aluminum, preventing wear.

This part fits the following BMW engines:
S54

This part fits the following chassis:
