Oil Pump Flow Rate

[Bob Bidonde]

A question that often arises about the Model A's oil pump is, "What is its flow rate?" The only info I could find is the flow rate is about 1 gallon per minute at a shaft speed of 1300 RPM. This correlates to a crankshaft speed of 2600 RPM, which in high gear with a 3.78:1 differential is a bit over 60 MPH.
Does anyone know of a factory spec for the oil pump's output?

I don't know he factory spec but Lawrie in Australia has done a lot of work on various pumps and heir flow rates before deciding on a pump for his Burtz. He might be able to help with real life figures.
