Message: [QUOTE="LurkerX, post: 1569480, member: 32918"] Just some math games for an idea of Flow rates... Melling is the only pump that published Flow information for their pump: 7 GPM at 700 RPM, 25 GPM at 4000 RPM Melling also states the following: 1) They meet or slightly exceed OEM flow under 2500 RPM 2) They are 10% higher than OEM at 3500 RPM If the M208 Flow is 25 GPM @4000 RPM, Flow will be 22 GPM @ 3500 RPM. 90% of 22 GPM is 20 GPM. I will therefore say that the OE LPOP is 5 GPM @700 RPM, 23 GPM @4000 RPM I say 5 GPM @ 700 RPM because the 14 slot gerotor has more loss at low RPM than the 10 slot, and fill cavitation will be magnified due to leakage in the gerotor. Melling also decreased gerotor thickness by 30%. DieselSite's gerotors are the same thickness as OE. Assuming a linear increase in volume (because I don't have anything better to spitball): LPOP73 should flow 6.5 GPM @700 RPM, 32.5 GPM @4000 RPM. [/QUOTE]
