The GPM flow difference between the R and standard filter is staggering. How much does a high volume R or LA oil pump flow?


Comparing the two filters, if one has a third of the filtering capacity, that translates into a third of the pressure drop so for a constant inlet pressure, three times the flow (roughly).
