Each pulley is machined from 6061-T6 billet aluminum and anodized for wear resistance and environmental protection in demanding marine-use conditions.\u003c\/p\u003e\n\u003cp\u003eThe pulley design includes lightweight pocketing to help reduce rotating mass, a guarded outer profile to help reduce unwanted belt wandering during hard running, and engraved running diameter identification for easier service and setup verification. Pulley dimensions are based on the running diameter.\u003c\/p\u003e\n\u003cp\u003eThis product is available with finish and diameter options. Finish options include clear anodized and blue anodized. Available running diameters include 3.00\", 3.25\", 3.50\", and 3.75\".\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eStock pulley reference:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eMercury Racing 600 SCI: 4.00\" stock diameter\u003c\/li\u003e\n  \u003cli\u003eMercury Racing 700 SCI: 3.50\" stock diameter\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eGeneral pulley sizing note:\u003c\/strong\u003e As a general rule of thumb, every 0.125\" pulley change is approximately 0.75 PSI of boost change, increasing or decreasing depending on pulley direction and the full drive combination. Actual boost change can vary based on engine setup, supercharger configuration, belt system, operating conditions, PCM control strategy, calibration, and supporting hardware. On stock PCM-controlled applications, pulley changes may not change boost levels without the proper supporting calibration and setup.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eApplication note:\u003c\/strong\u003e Whipple supercharger pulleys are application-specific. Verify pulley diameter, rib count, belt system, calibration requirements, and application before ordering. Do not order this pulley for a different application unless compatibility has been confirmed.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eReturns note:\u003c\/strong\u003e There are no returns or exchanges for used pulleys.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cu\u003eKey Features\u003c\/u\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e10-rib supercharger pulley\u003c\/li\u003e\n  \u003cli\u003eDesigned for compatible Mercury Racing 600\/662\/700 SCI applications\u003c\/li\u003e\n  \u003cli\u003eBillet 6061-T6 aluminum construction\u003c\/li\u003e\n  \u003cli\u003eClear anodized and blue anodized finish options\u003c\/li\u003e\n  \u003cli\u003eAvailable in 3.00\", 3.25\", 3.50\", and 3.75\" running diameters\u003c\/li\u003e\n  \u003cli\u003eEngraved running diameter identification\u003c\/li\u003e\n  \u003cli\u003eLightweight pocketed design helps reduce rotating mass\u003c\/li\u003e\n  \u003cli\u003eGuarded profile helps reduce belt wandering during hard running\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Whipple Superchargers","offers":[{"title":"Default Title","offer_id":56180576289090,"sku":"SCP-MR-10-4","price":295.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0999\/6002\/9506\/files\/F198648188.jpg?v=1789511682","url":"https:\/\/whipplesuperchargers.com\/products\/whipple-10-rib-supercharger-pulleys-for-mercury-racing-600-662-700-sci","provider":"whipplesuperchargers","version":"1.0","type":"link"}
