The BBI lightweight underdriven crank pulley is designed for Porsche owners who are looking for a easy bolt-on 7-10 rear wheel horsepower. The CNC machined pulley fits all Porsche 987.1 Boxster and Cayman cars. The idea of the underdrive pulley is that it will reduce demand that the stock pulley puts on the power steering pump at high engine revs. Not only will this preserve the longevity of the pump, it will also improve performance, throttle response, and give the track racer a car to be confident in. Since the pulley is lighter then stock, the rotational weight reduces load on the engine slightly. This pulley kit includes the removal and install tool in addition to a new bolt for easy install. With the inclusion of these tools, you can switch back to the stock pulley if needed for warranty purposes. This is an absolute must for track drivers! This pulley fits the Generation 1 05-08 Porsche Cayman or Boxster 3.2L and 3.4L engines. This pulley will also fit the Generation 1 05-08 997 Carrera 3.6L engine.
