{"product_id":"f-1a-91-supercharger-head-unit","title":"F-1A-91 Supercharger Head Unit","description":"The ProCharger F-1A-91 supercharger head unit is a self-contained, high-performance centrifugal supercharger engineered for both modified street engines and hardcore racing applications. It utilizes a custom 7075 billet aluminum impeller, a CNC-machined transmission case, and a patented compound bearing design to provide reliable, high-boost performance. The unit is capable of supporting up to 1,200 horsepower with a maximum airflow rating of 1,600 cfm and can handle up to 38 psi of boost.\n\nThis is a head-unit-only component; the pulley is not included with the purchase. The unit features an internal 5.40:1 step-up ratio and a 3.75-inch inlet diameter with a 3.0-inch outlet. It is designed for self-contained oiling with a 4 oz oil capacity.\n\nPlease note that this is a specialized performance component. Because this is a head-unit-only product, users must ensure compatibility with their specific mounting bracket systems and pulley setups. It is not a universal-fit part for all vehicles, and fitment will depend on the custom application requirements of your build.","brand":"ProCharger","offers":[{"title":"Default Title","offer_id":52663363305784,"sku":"PC335A-001-A","price":5048.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687529547.jpg?v=1784326258","url":"https:\/\/store.motormia.co\/products\/f-1a-91-supercharger-head-unit","provider":"MOTORMIA","version":"1.0","type":"link"}
