{"product_id":"supercharger-pulley-upgrade","title":"Supercharger Pulley Upgrade","description":"It includes an interchangeable pulley drive ring and a stock-appearing front pulley cover, both anodized in black. All fasteners are stainless steel or zinc plated for durability.\n\nThis specific 2.85\" pulley is intended for street applications and is quoted to add approximately +3 to +4 lbs of boost. Changes to boost levels are simplified by swapping the outer pulley drive ring. However, any boost level changes necessitate appropriate PCM revisions and the correct supercharger belt. Specific belt recommendations include the Gates K100572HD for use with a stock crank pulley (achieving 15-16psi) or the Gates K100594HD for use with an ATI Crank pulley (achieving 17-18psi).\n\nInstallation of this pulley requires custom PCM calibration\/tuning. The 2.85\" pulley works well with Mopar Demon fuel injectors, while smaller pulleys like the 2.75\" may require larger injectors such as the ID1050. It is recommended to purchase the HHP Hellcat Crank Pin Kit to complement this pulley upgrade. The pulley is intended for professional installation only, and installation instructions are not provided. Users assume all risks, and installation may affect vehicle warranty.","brand":"MetcoMotorsports","offers":[{"title":"Default Title","offer_id":52689066656056,"sku":"HCP2.85","price":279.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687380283.jpg?v=1784901239","url":"https:\/\/store.motormia.co\/products\/supercharger-pulley-upgrade","provider":"MOTORMIA","version":"1.0","type":"link"}
