While
both our temps are above the nominal recommended, I have found that
for
short duration, there does not APPEAR to be any problem. I know Tracy
encounters (or did with the old 13B) the same conditions with no
apparent
problems. I think we would both feel a bit more
comfortable with temps that
stayed below 200F (and I do use that as my
max red line for oil), they only
way I know to do that is to size your
coolant system for climb conditions
which means it will be oversized for
cruise with resulting excessive drag.

Ed,
Consider the air exhaust rather than considering the intake sizes. Air,
in a cooling system does not act the way we think it does. If it doesn't like
the flow pattern, it will stop.
You can use a manometer (make it out a clear tube) to look at air
pressure differentials. Don't forget about cowl flaps.

I agree, Rich. Total air flow through the system
rather than inlet or exit size is what really counts. So any undo
restrictions on either side to the cooling core can cause problems. The
fact that you have one side is done well and properly means nothing if the air
flow on the opposite side of the core is poor.
