Volume of water doesn't do it, area of radiator is what's needed to maintain acceptable water temperature.

I'm still not convinced that the A/W has enough contact time with the air to reduce the temp adequately, but it is the easiest system to package, and I'm only hoping for ~230hp (engine/SAE) so the area necessary should be fairly easy to calculate.

Anyone with an aftercooled 124 here?
