RD Sport Power Pulley S85 V-10 Set BMW M5 E60 07+

The Power Pulley is a smaller diameter pulley engineered to replaced 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 usally absorbed by driving these components.

The RDSport Power Pulley is made out of aerospace-quality 6061-T6 aluminum and is then anodized i the traditional RDSport Blue. It is supplied with the 2 shorter Micro-V belts that compensate for the smaller diameter of the pulley. On the 8 cylinder M3 we have seen a consistent gain of around 10HP, which make the power pulley option a very effective performance upgrade. Installation takes approxdimately 2.5 hours.
