Dinan's lightweight crankshaft pulley is constructed of Aircraft grade billet 6061 aluminum that is anodized black and engraved. It does not modify factory harmonics or dampening and safely underdrives the belt driven water pump, alternator, AC and power steering to reduce parasitic power loss on the M3 engine. It produces a peak gain of + 11 horsepower @ 8400 rpm and + 7 lb-ft torque @ 8400 rpm on a stock car.
The kit includes lightweight pulley and shorter belts for bolt on installation.
Please note that BMW changed the belt configuration from a single-sided power steering and AC belt to a double-sided belt for M3's that were produced after May 2008. Please check with your dealer to find the correct Dinan part number below.
