The Power Pulley is a smaller diameter pulley engineered to replace the OE crankshaft pulley. Since it is smaller in diameter, it drives the auxiliary accessories at a reduced rpm and reclaims some of the parasitic loss that is usually absorbed by driving these components.
The RDSport Power Pulley is made out of aerospace-quality 6061-T6 aluminum and is then anodized black for a factory look. It is supplied with the 2 shorter Micro-V belts that compensate for the smaller diameter of the pulley.
On the 10 cylinder M5 we have seen a consistent gain of around 10HP, which make the power pulley option a very effective performance upgrade.
Installation takes 1.5-2.5 hours
List: $450 plus shipping
