New Schumann Low Volume Drag Race Oil pumps for SBC.

In a typical OE application, engineers calculate the bearing clearances, journal sizes an so forth throughout the engine. From there they can estimate the volumetric requirments for oil. Then they design a pump that is 30% larger than the maximum requirements. But in today\'s drag racing engines tighter clearances and lighter oil are run and experts say that the extra 30% of oil is not needed and just robs extra horsepower pumping it through the engine.

Schuman sbc pumps have several additional features over the stock pump. On the driven shaft in the pump they have taken the time to machine oil retention grooves the length of the housing,this gives oil a place to flow and in exchange has a higher change over rate of oil. The rotation of the oil pump actually hinders the oil from getting in there as it is being thrown to the outside by centrifugal force. a notch is machined in the bottom of the floor of the pump housing, under the gear that takes oil from the pressure side of the pump and pushes it underneath the gear which is chamfered and a oil groove is machined in the oil hole to insure oil is getting in there.

All schuman pumps are built using a custom one off casting, they do not use cut down gears and spacer plates to reduce the volume of oil. Our gears are custom built and made length specific along with the pump housing itself and all of this is at a third of the cost.


Schumann oil pumps have the following unique characteristics not found in other pumps:

Full flow driven shaft oiling

Anti-aeration bleed off of oil supply

chevy oil pumps have high strength iron alloy casting and casting technique that eliminates 80% of porosity (70,000 psi)where as a typical pump has a more porous 35,000 psi design.

each unit is built with precision tolerance machining.

The unit features a drilled cap screw for easy cleaning and oil pressure spring changes.

Exact mesh gear set to housing bore yields highes idle psi.

Mounting bolt neck to housing is 150 grams heavier than typical chevy industry oil pump.

each unit includes extra long bolts to accommodate aftermarket performance bolt-on screen assemblies.

Also included are three spring combinations for desired oil pressure selection (55lb) (65-70lb) and (80-90lb)
