Bill,
I don't think Gordon is running a rotary, so the 2/3 - 1/3 rule
probably doesn't apply. I have no idea what the water-oil ratio of is
for a 4.3L Chevy V-6, but I'd bet that info is available somewhere on
the internet.

Gordon, the oil cooling required in a rotary is higher than a standard
I.c.e. The oil cooling is about 1/3 of the total cooling. There are lots of
"rules of thumb" on cooling. Typically about 3 ci of heat exchanger per hp.
That would be divided 2/3 water and 1/3 oil cooling. Ducting changes things
dramatically but that is a start.

I’m thinking about radiators for my 13B Defiant. I’ve noted some
automotive radiators integrate oil and transmission fluid cooling with the
engine coolant heat exchanger. Has anyone looked at these as a means of
integrating the oil and water cooler for an aircraft application? Does
anyone have an estimate of the oil and transmission heat load in a typical
GMC 4.3 L Jimmy?****
