OIL SYSTEM RS W/C M8

Quieter and smoother engine operation Increase oil pressure, scavenge volume and engine oil flow Engine temperatures run 15°-25° cooler Oil temperatures run 15°-30° cooler 10-30 lbs more psi of oil pressure Eliminate wet sumping, blow by and oily air cleaners Test results show 2 horsepower gain and 2 ft./lb. of torque gain to the rear wheel on M-Eight Includes a Race Series® oil pump, Race Series® full-travel or short- travel hydraulic roller lifters, High Flow camplate and cam installation kit, cam bearing, cam/​crank bolts and washers, engine and fastener assembly lube Billet 7075 aluminum oil pump is 50% harder and stronger than the factory pump; holds tighter tolerances under temperature Race Series® full-travel 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 M-Eight front exhaust camshaft lobe flange 42% more scavenge volume with port sizing, matched passages and holes to the engine case 68% more oil volume to the crankshaft and connecting rod bearing M-Eight Water-Cooled™ motor oil pump has 30% more pressure gear volume over stock and 53% more scavenge gear volume over stock M-Eight Oil-Cooled™ motor pump has 27% more pressure and scavenge gear volume over stock Race Series® oil pumps feature increased scavenge side kidney port volume over HP+ oil pumps Race Series® short-travel hydraulic lifters have .115” of total travel and will increase rpm by decreasing valve float and valve-train harmonics while maintaining a quiet engine The travel reduction reduces the amount of oil that is required to fill the inside of the lifter which reduces oil aeration inside the lifter on steep, fast action high lift camshaft lobes Made in the USA M-Eight engines must check clearance on front exhaust lifter to camshaft flange fit. Optional FUELING® X ARP bolt kit available for the high flow camplate PART #0932-0192 and HP+ or RS oil pump combo. See PART #2401-0993, optional ARP oil pump bolts do not use washers. FUELING® test results show as much as 50% reduction of engine sump oil level. Includes FUELING® High Flow billet camplate made from 7075 aluminum which is 50% harder and stronger than the factory or FUELING® OE+ camplates Increases oil flow and volume by enlarging the oil pump reservoirs and critical oil passages including matching the oil portholes throughout the camplate to the portholes in the engine case which increases engine oil flow to the lifters, piston cooling jets, crankshaft and rod bearings FUELING® oil pumps are bench tested, the relief valve is seated and sealed to a minimum of 30 psi with full pop off at 55-60 psi Increased oil volume from the larger gears and properly sized passages along with the pressure relief valve seat and seal from these oil pumps is essential for proper oiling system function FUELING® oil pump and camplate combination eliminate common pressure and scavenge issues associated with the factory oiling systems FUELING® M-Eight oil pumps have the groove machined on the back cover to accept the factory crank bearing seal
