Ken,
Here's what I published on March 18th.
G'day,
I am posting the following for information purposes only; I am not suggesting, recommending, commending, or anythinging the Melling
high flow pump P/N M-22-FHV.
I wanted to find out how much oil it flowed so I called Melling Technical Support and was advised that at idle (700-800 rpm) the
pump would deliver 3.25 GPM with the bypass set at 58 psi. The bypass could be set higher at 65 psi. The tech rep noted at 5000 rpm
their pump would deliver around 7 GPM and the OEM pump around 3.
Regards,

Seems to me there's one important consideration that hasn't been much
addressed in this high volume oil pump discussion: With our gear pumps,
the volume passed is directly related to the engine speed. I suspect Dick
Paterson's affinity for the high volume pump is at least partially based on
the low speeds at which we operate our engines.
JMHO,
Ken H.
