Richard. Your oil  flow rate seems very high. Fuel consumption off 30
litres/hour at 6000 rpm and .5l of oil gives a ratio of 60 to one. Most

of

us run around 120 - 150 to one. Does the pump actually run at crank(e

shaft)

speed?

Good point Ian. I don't think it does.

Hi Ian,
you are right, the pump does run at 1/2 the crank speed, however, to put the
flow rate in relation to what you see in running the engine, this factor is
immaterial. It certainly is important for the person doing the test.
The test setup does not account for the setting of the linkage in a car or
any other use. The test data, however, is thought to give you a basis for
modifying a linkeage to the oil flow rate you want on your engine, copying
the car linkage characteristic may not be the best solution for an air
plane.
