Agency Power's lightweight crank pulley for the Porsche Cayman or Boxster S 3.4L, normally aspirated engine, is the perfect bolt-on part to enhance the responsiveness and performance of your vehicle.  Made in the USA, our CNC Machined pulley is made from Billet 6061 Aluminum modeled from the factory pulley and under sized to add power.  The pulley is underdriven by 16% and is fully balanced for reliability and longevity.  The design of the pulley incorporates 6 beefy spokes with chamfered edges to be lighter that stock.  With less rotational weight, this means less load on the crank and more horsepower.  Utilizing CAD design elements, the pulley was stress tested to ensure is strength in running upwards of 9000rpm.  Where competitor pulleys have failed because of lack of material and attempts to cut weight, the Agency Power pulley has been thoroughly tested.  Each pulley features a precision timing mark.  Finished in our new smoke gray anodizing, each pulley has been laser engraved with our logo and part number.  To ensure an easy install, the pulley includes the required belt to replace your stock one.  Expect to have faster throttle response, quicker revs, and gain up to 7 horsepower with this light weight pulley kit!
