Distributor gear solution idea

[mylesdw]

I'm guessing that the pressure section of a dry sump pump won't make much of a lift pump to pick oil up from a sump, they are designed to have the input oil higher than the pump inlet. What about a dry sump pump with one scavenge stage and plumb the scavenge directly to the pressure stage; maybe with a small reservoir or suitable pressure regulation?

That is exactly what I was thinking, along with a question as to if the oil filter could be between the scavage and pressure section. That would keep the filter at the lower pressure, if it didn't hurt flow.

I'm guessing you'll then be pumping a mixture of oil, blow by gases, and air to the bearings.

Only if the pick-up in the sump became uncovered which should not be the case since we are using the sump as the main oil reservoir.

The oil coming out of the oil pan sump would be exactly the same as what the internal pump is pumping now. The only differance would be that the oil is being pumped by an externally mounted and belt driven pump. The pump should not add air to the oil.

Actually there may be available an external pump designed for this service, although I never heard of one.

they do make them.
