Legends cars (Dwarf cars on some circuits) are 5/8-scale replicas of 1930s model Fords and Chevys, powered by four-cylinder, 1100- to 1200cc air-cooled motorcycle engines rated at upward of 150 horsepower. Because the engine oil is subjected to extremely high RPMs and is common to the gear box and clutch pack, lubricant is subjected to far quicker viscosity breakdown and heat buildup, sometimes in excess of 300°!! The FLUIDYNE solution is a compact (16 x 10. 5 x 1 inches) single-pass, all-aluminum oil cooler with patented inner turbulator for maximum performance!Test data collected by the champions show an unbelievable drop of 70° to 90°F in oil temperature. Noticeable differences at the end of several 30-lap mains include fresh oil appearance and odor, excellent wear patterns on cams, rocker arms and bearings, and extended clutch life. FLUIDYNE's Legend/Dwarf Engine Oil Cooler combines an integrated mounting bracket for ease of installation, with compact high efficiency design for the obvious choice for your engine oil cooling needs!
