Geesh, now i'm confused. I have never seen anything but a Gilmer belted power source for an American engine dry-sump system. Perhaps electric ones exist, but i wouldn't trust an electric motor in a race car for such critical duty on expensive motors.
So, sans some sort of slip clutch or something on the dry sump pumps, pre-oiling requires a separate electric pump motor with associated checkvalves and hoses or an accusump system (my choice).
i have seen an electric drill powered pump that is externally powered, just before start-up. At least it wets the journals. And modern oils do "cling" much longer on surfaces, particularly on close fitted non-race engines.
i have even seen guys slip a flexdrill line down the distributor hole to run the wet sump pump, with the distributor removed, of course. This is the el cheapo way, but perhaps bettter than zip? Big risk of re-installing the dist wrong just before the race, though.
Is there something here i am not grasping?
