One question! When you enlarge the oil sump do you have to extend
the oil pickup tube to lower the strainer.

It would be nice but no if you always keep the oil level in
the pan several inches above the oil pick up tube.
You still get the heat storage benefit of the increased
amount of oil which delays the temperature rise on take
off and climb out.

Rino: Having only done this in old car racing days where larger mains, etc.
produced new failures, though I have planned for it on rotary (when I get
my
round2it.), I can only tell you we usually dropped pick up tube once got
enough clearance on everything to where oil usage was sufficient to require
it. You know, the old if it don't use it, you aint' running it hard enough
idea/excuse. But, the initial idea was to add air conditioner condensors
and
then oil capacity for cooling, even to point of drilling drain holes into
heads and let oil run back into couple of holes spudded into top of pan on
each side, all to get back into pan. On one of these, where you are
probably
not or shouldn't be sucking and/or burning enough oil to require additional
capacity for time of use, I would think it would not be necessary, as added
capacity to help stabilize temp is expected to be benefit. But, now, if you
plan to tanker yourself around for enough hours to actually darn near run
it
out of oil, (long overwater flight, etc.) you certainly might want to
consider it.

Don't forget jofarr racing cars generate at least one G lateral
and longitudinal while most airplanes don't.

While not required, dropping the pickup tube to near the bottom of the pan
seems like cheap insurance. Scenaro: You're cruisng along at 12K ft over
rough terrain and 30 miles from the nearest strip. You smell burning oil,
maybe notice a wisp or two of smoke. Hmm-- "I've probably got a small oil
leak somewhere." Then oil pressure drops to zero and the engine starts
running poorly. "Dang--I sure wish I could use the oil sitting in the
bottom of the oil pan."
