FLUIDYNE Legends Cars (Dwarf Cars) oil coolers are crucial because the engine oil also supplies lubricant to the gear box and clutch pack. The lubricant is subjected to far quicker viscosity breakdown and heat buildup. During race conditions, oil sump temperatures commonly reach 300°F. Test sessions and data collected by the champions in the sport during and after actual races 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.
