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.
