Craven Speed MINI Lightweight Crank Pulley R53 MINI

  • The CravenSpeed pulley is a stock diameter (OEM sized) crank pulley, utilizing the original belt layout. Since the crank pulley diameter is unchanged, it maintains alternator output at exactly stock output levels so you need not worry about flat batteries or weak charging capabilities. Through extensive weight savings afforded by 6061 aircraft aluminum construction, power gains of up to 10% are available depending on how your MINI is set up. CravenSpeed crank pulleys come fully balanced and counter-weighted, and feature anodizing for superb wear resistance & strength.

    The rule of thumb is that each pound of weight taken off the engines rotating assembly is worth approximately 2.7HP. The concept is that the crank is a parasite; it does not put power to the drivetrain but still requires the energy produced by the engine to rotate. When you reduce this parasitic weight, you release power that was previously used only for spinning the supercharger and alternator.

    Fits all 2002-2006 MINI Cooper S, and Convertible Cooper S models through 2008.
