They are absolute crap, just like all automotive pumps. But they are good enough if you think about what they are. The racer has a giant 3 stage dry sump pump, and it even has powdered metal gears. Loosing oil pressure does not hurt a rotary. Operating the engine at length with no oil pressure hurts a rotary. Lynn E.
