That helps but it doesnt show the other half.
That diagram does not include any of the actual engine lubrication system.
(To be honest, all that diagram shows is how to have a nice oil reservoir that does not come in contact with the engine oil in any way ;-) I hope no-one is running it exactly like that....
I assume that the CB pump is the dual (4 gear type), so the 'main' pump body must scavenge oil from the case sump and pump it out through.....:
A - the oil filter housing bracket (requires a block off plate or threading the case)
B - the oil pressure relief housing hole (requires some special adapter fitting- thread = TBD)
C - the oil cooler bracket (requires a block off plate or threading the case).
( all of the above after running through some of the oil galley passages )
Also, after looking at the 914-6 oil system, the above does not seem to be optimal in that:
in the 914-6 version
, the scavenge pump blows directly into the tank.
I would think that foam would be less effective at cooling if it goes through a cooler.
the above diagram does not seem to be optimal in that The extra pump is being used to ONLY circulate through the filter, cooler, and back to the tank.
I thought one of the main reasons to run a dry sump was to use the extra pump "loop" to run uninterrupted (read no air bubbles) back to the engine oiling system.
The diagram does nothing to help there.
After thinking about it for a while it seems the best design is:
Use a 4 gear pump (one set of gears works exactly like the stock pump, no block-off).
Stock-like-pump-gears just scavenge from the engine sump and blows out through an (optional remote or) stock oil filter location into a catch tank.
No pressure relief required since it is open ended into the catch tank
Extra pump gears (external to the stock pump - might require extra clearance) pull in through bottom of catch tank and blow through:
Oil cooler
Additional filter (if desired)
Then back to engine lubrication system at high pressure.
So the diagram above still only addresses a small piece of the puzzle.
I will try to draw up the various options for the system, but will take some time.
It seems that most of the confusion about these systems is the lack of clear plumbing diagrams.
