Includes FUELING® High Flow billet camplate made from 7075 aluminum which is 50% harder and stronger than the factory or FUELING® OE+ camplatesIncreases 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 bearingsFUELING® 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 psiIncreased 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 functionFUELING® oil pump and camplate combination eliminate common pressure and scavenge issues associated with the factory oiling systemsFUELING® M-Eight oil pumps have the groove machined on the back cover to accept the factory crank bearing sealQuieter and smoother engine operationIncrease oil pressure, scavenge volume and engine oil flow42% more scavenge volume with port sizing, matched passages and holes to the engine case68% more oil volume to the crankshaft and connecting rod bearingEngine temperatures run 15°-25° coolerOil temperatures run 15°-30° cooler10-30 lbs more psi of oil pressureM-Eight Water-Cooled™ motor oil pump has 30% more pressure gear volume over stock and 53% more scavenge gear volume over stockM-Eight Oil-Cooled™ motor pump has 27% more pressure and scavenge gear volume over stockEliminate wet sumping, blow by and oily air cleanersTest results show 2 horsepower gain and 2 ft./lb. of torque gain to the rear wheel on M-EightIncludes 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 lubeBillet 7075 aluminum oil pump is 50% harder and stronger than the factory pump holds tighter tolerances under temperatureRace Series® oil pumps feature increased scavenge side kidney port volume over HP+ oil pumpsRace 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 flangeRace 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 engineThe 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 lobesMade in the USAOptional 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.M-Eight engines must check clearance on front exhaust lifter to camshaft flange fit.
