Features
- Billet 7075 aluminum oil pump, which is 50% harder and stronger than the factory pump, holding tighter tolerances under temperature
- Short travel hydraulic lifters have 0.115" of total travel and will increase rpm by decreasing valve float and valve-train harmonics while maintaining a quiet engine
- Deeper scavenge kidney ports over the HP+ series for even more scavenge flow volume
- 30% more pressure gear volume over stock for M-Eight Twin-Cooled motors
- 53% more scavenge gear volume over stock for M-Eight Twin-Cooled motors
- 27% more pressure and scavenge gear volume over stock for M-Eight Oil-Cooled motors
- 42% more scavenge volume with port sizing, matched passages and holes to the engine case for M-Eight Twin-Cooled motors and M-Eight Oil-Cooled motors
- 68% more oil volume to the crankshaft and connecting rod bearing for M-Eight Twin-Cooled™ motors and M-Eight Oil-Cooled motors
- 15°-25° cooler engine temperatures for M-Eight Twin-Cooled™ motors and M-Eight Oil-Cooled motors
- 15°-30° cooler oil temperatures for M-Eight Twin-Cooled™ motors and M-Eight Oil-Cooled motors
- 10-30 more psi of oil pressure for M-Eight Twin-Cooled™ motors and M-Eight Oil-Cooled motors
- Increases oil pressure, scavenge volume and engine oil flow
- Reduces wet sumping, blowby and oily air cleaners
- Magnets in oil pump to help protect gears and pressure relief valve
- Test results show 2 hp gain and 2 ft/lb of TQ gain to the rear wheel on M-Eight
