Dinan Product Description

Dinan’s underdrive pulley is designed to increase power by reducing parasitic drag on the engine from spinning the alternator, water pump and AC compressor. This is accomplished by slowing down the speed of these accessory drives that rob power from your engine. Dinan has done extensive hot weather testing so you can be assured that your engine is safe. The Dinan underdrive pulley is made of aircraft quality 6061 alloy, is anodized black and does not modify your harmonic damper as some underdrive pulley kits do which can be harmful to your engine.

Note: 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:

  • D560-0003 for 2008-5/08 production date with single-sided power steering & AC belt
  • D560-0004 for 6/08-2013 production date with double-sided power steering & AC belt

Benefits:

  • +11 HP @ 8400 RPM, +7 lb/ft @ 8400 RPM
  • Eliminates parasitic drag from accessories
  • Made from 6061 aircraft aluminum & anodized black
  • Does not modify the harmonic damper
  • Extensively tested to ensure proper cooling system operation
