There are many variables, firstly how many revolutions per minute is the engine turning when you measure the flow?Does anyone out there know how many litres per minute the stock oil pump puts out?
I figured it would be fairly low, given how long it takes for the oil in the tank to get up to temperature. If my brain wasn’t completely mush, I could measure the piston accurately and try and calculate the flow, except with the design of the pump, it only spurts out a portion of the oil in the chamber.0.625" diameter piston with about 1/4 to 1/3 in area machined flat on one side.......has a stroke approx. 1/4" and does a full rotation in 15 turns of the crank shaft.......Not dissimilar to squirting an oil can........
Thanks Dan, much appreciated. Exactly what I was looking for. I have a new pump sitting on the bench and may test it at some point assuming a test jig can be made in less than 1/2 a day.I have some notes on this from when we were testing oil flow rates when upgrading our oiling system to a trochoidal pump.
My notes state that a standard Vin pump was 230ml/min @ 2800 RPM, i'm pretty sure i got that figure from 40 years on. hope this helps
Cheers
Dan
