It should work but you still need enough heat exchanger to handle you BTU needs. So you would need a 20-30% bigger radiator for things to work.

Todd,
 
 Are you using this as your sole means of oil cooling, or as a supplement? I've always been intrigued by the idea of an oil-water exchanger, but have yet to hear of anyone successfully using one as a sole means of cooling a rotary in an aircraft application. Something like this would sure simplify my plumbing and eliminate some weight. I'm tempted.

Hi Guys
    Quite some while back Mark Sietle put a Mocal oil cooler in his plane, which I was quite impressed with. Recently I began watching ebay for one of these coolers and a few weeks ago I hit paydirt.
