Hi Mike,
Glad to have you back.  Yes, I'm running a custom Fluidyne oil/water
exchanger, but it augments the oil/air exchanger, not replaced it.  If it
was 25% larger, it might handle all of the heat load of the oil, but I
haven't tested that theory yet.  I'm sure you realize that the water
radiator has to be large enough to handle the extra btu's, mine apparently
was.  If you want more detail, let me know and I'll send you pictures.

Mark S.
