Feuling Race Series Oiling System For Harley Oil Cooled Milwaukee-Eight Feuling oiling system kits combine all the needed components to finish your engines oiling system. Kits increase oil pressure, oil volume, engine oil flow and return oil scavenging for a quieter and smoother running engine. Includes a billet 7075 hard anodized oil pump which is 50 harder and stronger than the factory pump holding tighter tolerances under temperature. Race Series hydraulic lifters have a full .200 of total travel designed with a slower bleed down rate to handle heavy valve spring pressures, increase engine RPM before valve float and feature increased roller clearance for steep ramped camshafts and clearance for the camshaft front exhaust lobe flange. High Flow billet camplate made from 7075 aluminum which is 50 harder and stronger than the factory camplates. Feuling increases oil flow and volume by enlarging the oil pump reservoirs and critical oil passages including matching the oil port holes throughout the camplate to the port holes in the engine case which increases engine oil flow to the lifters, piston cooling jets, crankshaft and rod bearings. Features 27 more pressure and scavenge gear volume over stock 42 more scavenge volume through port sizing, matched passages, and holes to the engine case 68 more oil volume to the crankshaft and connecting rod bearing 15-25 cooler engine temperatures 15-30 cooler oil temperatures 10-30 more PSI of oil pressure Reduces wet sumping, blow by and oily air cleaners Test results show 2 HP gain and 2 ft/lbs of TQ gain to the rear wheel Feuling test results show as much as 50 reduction of engine sump oil level
