Feuling Race Series Oil Pump/Camplate Kit For Harley Davidson Twin Cooled M8

Sku: FEU-7199

Brand: Feuling

Feuling Race Series Oil Pump/Camplate Kit For Harley Davidson Twin Cooled M8


  • Increase oil pressure, oil volume, engine oil flow and return oil scavenging
  • Quieter and smoother engine operation
  • 15-25 degree cooler engine temperatures
  • 15-30 degree cooler oil temperatures
  • 10-30 more psi of oil pressure
  • Reduces wet sumping, blow by and oily air cleaners
  • Test results show 2 horsepower gain and 2 ft/lbs (EU: 2,71 Nm) of torque gain to the rear wheel on M-Eight
  • Feuling test results show as much as 50% reduction of engine sump oil level
  • 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® M-Eight oil pumps have deeper scavenge kidneys when compared to the HP+ kidneys for increased scavenge volume)
  • Also includes Feuling® High Flow billet camplate made from 7075 aluminum; which is 50% harder and stronger than the factory or Feuling 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
  • Oil pumps are bench-tested; the relief valve is seated and sealed to a minimum of 30 psi (EU: 2,06 bar) with full pop-off at 55-60 psi (EU: 3,79 bar - 4,13 bar)
  • 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
  • Feuling oil pump and camplate combination eliminates common pressure and scavenge issues associated with the factory oiling systems
  • 30% more pressure gear volume over stock, 53% more scavenge gear volume over stock and 42% more scavenge volume with port sizing, matched passages and holes to the engine case
  • Made in the U.S.A.

RACE SERIES kits include FEULINGS 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.

RACE SERIES Kits 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 M-Eight oil pumps have deeper scavenge kidneys when compared to the HP+ kidneys for increased scavenge volume.
