This Underdrive Pulley Kit by Dinan is designed to increase power by reducing parasitic drag on the engine by slowing down the speed of the alternator, water pump, and AC compressor- all of which steal power from your engine.  This adds approximately 11hp at 8400rpm and 7tq at 8400rpms on a stock car.  Dinan is known for the safety of their products, this specifically is made of 6061 alloy, anodized black, and does not modify your harmonic damper.  As with all other Dinan products, this does not void your factory warranty.




After May 2008, BMW changed the belt configuration from a single-sided AC belt to a double-sided belt.  Please check with your dealer to find the correct part number.
