The Banks Power R866SC is a turn-key supercharged Duramax diesel V8 capable of 600-650 horsepower. Each R866SC features custom pushrods, camshaft, valve springs, wet sump oil pan, and accessory drive system designed by Banks Power. In the middle sits a Banks Power two-piece aluminum intake manifold with a custom air-to-water intercooler. On top of that is a Whipple billet 3.8 L (Gen V) supercharger. Listen to Gale explain the difference between a factory Duramax and the R866SC.
