The Feuling cam support plate for Twin Cam engines increases engine oil flow and volume by enlarging critical oil passages and the oil pump reservoirs. The cam plate is blue printed and matched to the Feuling or TPD oil pump, allowing the Twin Cam engine to take full advantage of the increased volume from these oil pumps. The cam support plate is made from 7075 billet aluminum and features a hardened anodize finish for increased strength and hardness. This allows elimination of the pinion shaft bushing. Other advantages are increased oil flow to pinion shaft and connecting rod bearings, and tighter cam bearing bore tolerance for improved press fit. Due to the improved flow, the cam support plate helps to decrease engine temperature. Pressure relief valve and spring are designed for increased volume and pressure, eliminating the need to stretch the spring or use a shim. When matched with the Feuling or TPD Race Pump rear wheel power gains of 3 Horsepower and 4 ft/lbs of Torque are achieved. These cam support plates bolt into the stock location, include bearing retainer plate and hardware and are designed for use with the Feuling and TPD high volume oil pumps. Available for use with stock chains driven cams as well as for use with aftermarket gear driven cams.
