Hi Paul,
What is the sump capacity for the 13B turbo.
Your sump dwg has about .95 US gallon or 3.6 litre.
The manual give 5 quarts 1.25 US gallons or 4.73 litre with filter.
Would it not be benificial to make this a bit larger for our use.
Regards Don

I think so. If you have room. My O-470 is 12 US quarts and it is
only 230 HP.

They base the size of aircraft engine oil sumps to carry enough oil at
the highest "acceptable oil consumption rate" (which are VERY high-over
1 qt per hour) of the engine builder at the given fuel burn rate in the
airframe based on airframe fuel capacity so as to still have minimum
lubrication of the engine at fuel exhaustion, not cooling capacity. It
is in the FARs.
My lyc in a 60 gal plane has an 8 qt capacity.
With the rotary and very little oil consumption, you could base it on
just over min oil burn that gives acceptable lubrication What would that
be on a 60 gal tankage? Not much-so base it on engine lubrication needs.
