Monty,

If your coolant temp is limited with good oil = temps then=20 placing the oil to water exchanger between two radiators may be the best = solution. If your oil temp limited with good water temps then placing = the oil to=20 water changer after the last radiator before the engine = inlet should=20 work best. I have testing my both ways.

Mike,

Great to hear you are flying = again.

I don't know if you have seen some of = the new=20 water/oil heat exchangers?. They mount in the tank of the water = radiator. The=20 preferred installation would be a dual pass water rad where the front = tank is=20 divided. The water flows through 1/2 of the radiator and gets cooled = off. Then=20 it flows through the end tank past the oil cooler picking up heat. Then = it flows=20 back through the second half of the radiator and gets cooled off again = and=20 finally gets returned to the engine. This solves the "which hose do I = put the=20 oil cooler in" dilemma. It also can greatly simplify the ductwork and = make the=20 radiator more efficient. If you are thinking about re-doing your cowl, = it might=20 solve some of your problems.
