May be easier to do it off a gasoline engine. It would be interesting to know if shortening the housing and impeller 10% would get a 10% drop in volume pumped.
During the 1980s I ran an "outlaw" sprint car on dirt, (didn't drive it, you can hire crazy people for that) with a Peterson dry sump set up. I felt like it was way more pump than I needed. Never did play with that, making enough power was never an issue. Always wondered about that pump. I'm sure it was over-kill in size to cover their tails.

Ed,
Oil pump flow is measured in GPM. The flow will vary based on the relief settings.
Your best best is to call the tech guys at Peterson or Dailey.
