RD Sport Power Pulley Set BMW M3 E92
The Power Pulley is a smaller diameter pulley engineered to replace the OE crankshaft pulley. Since it is smally in diameter, it drives the auxiliary accessories at a reduced rpm and reclaims some of the parastic loss that is usually absorbed by driving these components. The RD Sport Power Pulley is made out of aerospace-quality 6061-T6 aluminum and is then anodized in the traditional RD Sport 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 of this products approximately take 2.5 hours.
