{"product_id":"bd11a-rebuilt-supercharger","title":"BD11a Rebuilt Supercharger","description":"The Powerdyne BD11a is a rebuilt, oil-less supercharger offered in a satin finish with either a straight or curved discharge. This unit has been upgraded with a JBP billet impeller for enhanced responsiveness and increased CFM, paired with a kevlar belt that may produce cog belt whine during operation.\n\nPerformance specifications include a maximum speed of 42,500 RPM for low-torque applications and 38,500 RPM for high-torque engines, a maximum boost of 16 PSI, and a maximum flow rate of 900 CFM, capable of supporting approximately 450 HP with a peak efficiency of 84%. The supercharger has a discharge outside diameter of 3 inches, an inlet outside diameter of 3.5 inches, a discharge inner diameter of 2.4 inches, and an inducer diameter of 3 inches.\n\nThis rebuilt supercharger includes new SKF input bearings, ceramic output bearings, and an HTD belt. It also features a new JBP billet impeller, a JBP input shaft, and all new stainless hardware and steel case clamps. A 12-month limited warranty covers all non-consumable components. It is important to note that Powerdyne Superchargers are recommended for stock engines and are not intended for high torque applications or race use, as internal drive belt breakage can occur in such scenarios.\n\nInstallation on high torque applications is not recommended and will void the warranty on the drive belt. A standard bypass valve is required for superchargers exceeding 6 PSI. Powerdyne units utilize manual belt tensioners, requiring a belt tension tool such as a Gates Krikit to achieve proper pressure. Excess belt tension that leads to bearing damage is not covered.","brand":"Powerdyne","offers":[{"title":"Default Title","offer_id":52663301013816,"sku":"BD11","price":900.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687526616.jpg?v=1784325763","url":"https:\/\/store.motormia.co\/products\/bd11a-rebuilt-supercharger","provider":"MOTORMIA","version":"1.0","type":"link"}
