{"product_id":"3-625-6-rib-5-bolt-supercharger-pulley","title":"3.625\" 6-Rib 5-Bolt Supercharger Pulley","description":"The Whipple 3.625\" 6-Rib 5-Bolt Supercharger Pulley is built for Whipple supercharger applications, engineered to provide precise fitment, durable construction, and dependable belt control. This pulley is machined from 6061-T6 billet aluminum and features a black anodized finish for long-term wear resistance and environmental protection.\n\nWhipple engraves the running diameter on every pulley and incorporates lightweight pocketing to reduce rotating mass. An integrated guard feature is included to help control unwanted belt wandering during aggressive use. Pulley changes are a well-established method for adjusting supercharger speed, which can impact boost levels and overall power potential when properly matched with supporting components and calibration. While a general guideline suggests that every .125\" of pulley change can affect boost by approximately 1 psi, actual results are application-dependent.\n\nIt is crucial to verify pulley specifications before installation, as there are no returns or exchanges on used pulleys.","brand":"Whipple","offers":[{"title":"Default Title","offer_id":52866649850168,"sku":"VMP-SCP-63625-5","price":149.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687411358.jpg?v=1787909431","url":"https:\/\/store.motormia.co\/products\/3-625-6-rib-5-bolt-supercharger-pulley","provider":"MOTORMIA","version":"1.0","type":"link"}
