{"product_id":"f-4x-140-supercharger-head-unit","title":"F-4X-140 Supercharger Head Unit","description":"The ProCharger F-4X-140 Supercharger Head Unit is an elite-tier centrifugal supercharger engineered for racers seeking ultra-high horsepower levels. Building on the foundation of the F-Series, this unit incorporates a large-diameter volute to provide massive airflow, utilizing precision-ground 9310 steel gears and a patented, ultra-high-speed compound bearing assembly. The design is optimized for durability in professional racing environments, featuring a self-contained oiling system that eliminates the need for external oil lines.\n\nTechnically, the unit is rated to support over 3,500 horsepower, capable of handling up to 60 psi of boost. Key specifications include a 5.47-inch inlet diameter and a 7.22-inch exducer diameter, providing the high-flow characteristics necessary for top-tier drag racing or endurance applications.\n\nInstallation of this head unit is intended for professional race applications and requires specialized knowledge of high-boost engine systems. Because this is a head unit-only configuration, customers must ensure they have the necessary mounting brackets, pulleys, and belt-drive systems compatible with their specific engine platform before installation.","brand":"ProCharger","offers":[{"title":"Default Title","offer_id":52663357440312,"sku":"PC318A-140-C-SP-T","price":12998.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687529544.webp?v=1784326226","url":"https:\/\/store.motormia.co\/products\/f-4x-140-supercharger-head-unit","provider":"MOTORMIA","version":"1.0","type":"link"}
