George,
That describes my cooling system exactly. Originally, I had the
oil/water exchanger first, followed by the oil/air exchanger. This
dumped a max amount of btu's into the water. By running the oil
through the oil/air exchanger first, then into the oil/water
exchanger, it now dumps as much heat into the air. The remaining heat
goes into the coolant. This only works if you have excess water
cooling capacity, which I did. Now the temps track within 5-8* of
each other. The drawback is the extra plumbing, and some extra
weight.

Why stop with the radiator? Move the oil cooler there as well to make this
approach worth all the effort. And there will be a lot of effort : )

Quite correct Tracy,
Nearly everyones favorite example the P-51 used stacked radiator and oil
coolers. My thought is if you go to the trouble of a wing mount or belly
scoop run a slightly larger radiator and one of the large fluidyne water to
oil coolers. (much to P.L's chagrin) Many nascar teams do use them. Mark
Stetle (sic) put one on his 20B powered Lancair and it has helped his climb
cooling a lot. His is a Lancair ES 4 place and seems to be cooling very well
now.

Bill,
Can't remember who - but the suggestion of an air cooler before the water
to oil cooler is a good one. Would certainly stop any possibility of oil
over heating the water and have the added benefit of the water heating the
oil.
