What I am really trying to get down to is this... How many liters per / minutes is passing through the filter. Now I know for a fact that "IF" the pump would be run with ZERO back pressure...that the pump will pump a great beat more then with back pressure. See there is a pressure regulator valve in the engine, once a given pressure is reached, the valve will open dumping the over pressure volume of oil back into the oil pan area...( without it passing through the filter ). Now is memory serves me right the valve start to open or opens at a pressure of 77 PSI. That's all well and great, but that still does not tell me what the volume of oil is that's being pumped.
And trying to get / find a email address to some Tech support at Honda...well thats next to impossible.
