Turner Motorsport Power Pulley Kit - E90/E92/E93 M3

Product Details

Get MORE HORSEPOWER and TORQUE on your 2008, 2009 and newer M3 coupe, sedan or convertible by replacing the stock crank pulley with this specially designed performance version. The Power Pulley reduces rotational mass and safely under drives your belt driven auxiliaries for reduced parasitic power loss. The end result: More power to your M3's rear wheels! Designed to give the best performance benefit with no sacrifices or compromises to your BMW's reliability. These have been tested on hundreds of cars before public release and there are simply NO DOWNSIDES to this upgrade.

CNC machined using aircraft grade 6061 aluminum billet, and anodized with a stealthy black coating. Others may advertise "their" crank pulley boasting higher numbers (using a smaller pulley profile), but we have concluded that for street and track driven M3s, this is the best size and design to ensure proper engine temp and auxiliary functionality. As the S65 M3 V8 engine doesn't use a traditional harmonic balancer, all factory harmonics and dampening are fully and properly retained. We've found this pulley alone adds 10 to 14 HP and 7 to 9 Ft/lbs Torque on a stock M3 with no other mods(!!).

The E9x M3 Power Pulley Kit includes:
(1) Underdrive Crank Pulley
(1) Correctly Sized Drive Belt
(1) AC Belt
(6) Allen Head Bolts
(1) Installation instructions

Fits the following BMWs:
2008+ E90/E92/E93 M3 6 Speed Manual Transmission

This kit uses readily-available, off-the-shelf belts - no difficult to find belts here! When you're ready for new belts, sets for 2008 manual transmission vehicles can be found here, and 2009+ manual transmission and all DCT vehicles can be found here.
