The KAVS Motorsport +5% larger alternator pulley is designed to reduce the speed of the alternator on the R50 MINI One and R53 MINI Cooper S when other engine modifications mean that the engine revs harder, causing it to spin faster. The advantages of the Kav's +5% larger alternator pulley are:-

• Increased life of your alternator
• More BHP; because the design of the pulley allows the belt to work more efficiently with reduced stress, so it reduces parasitic losses
  
• Allows you to run a higher rev limit for more performance

The KAVS Motorsport +5% alternator pulley is made from high quality steel and finished with a galvanic coat to ensure it'll stay looking great for many years to come.

1320's Kav's Motorsport +5% alternator pulley is also useful for R53 MINI Cooper S owners who want to use their standard OEM belt with Kav's Motorsport reduced supercharger pulleys from 11% up to 15% smaller sizes.
