{"product_id":"2-overdrive-crank-pulley","title":"2% Overdrive Crank Pulley","description":"The CravenSpeed Lightweight Crank Pulley is engineered to enhance the performance of R53 MINI Cooper models from 2001 to 2006. This 2% overdrive crank pulley increases the speed at which your supercharger operates, leading to higher boost levels and improved throttle response. The pulley itself is constructed from lightweight 6061 aircraft aluminum, significantly reducing rotating mass.\n\nFeaturing a durable anodized finish for exceptional wear resistance and strength, the CravenSpeed crank pulley is also perfectly balanced to ensure smooth operation. The R53 2% overdrive pulley weighs just 1.18 lbs, a substantial reduction that aids in releasing parasitic power losses.\n\nEach pound of weight removed from the engine's rotating assembly is estimated to be worth approximately 2.7 horsepower. By reducing the weight of the crank pulley, less engine energy is used to spin the supercharger and alternator, making more power available for acceleration. For those seeking less aggressive gains, CravenSpeed also offers a stock-size pulley that provides weight savings without the supercharger overdrive.\n\nThis kit includes a replacement OEM crank pulley bolt. While the R53's engine, like most modern engines, does not require a traditional harmonic damper due to advances in design and materials, this pulley is a direct replacement designed for safe and effective operation.","brand":"Lightweight","offers":[{"title":"Default Title","offer_id":52686622294328,"sku":"CRMC-0019","price":139.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/657807277.jpg?v=1784875387","url":"https:\/\/store.motormia.co\/products\/2-overdrive-crank-pulley","provider":"MOTORMIA","version":"1.0","type":"link"}
