Hi Pual,
Thank you for your response.
I was looking for info on radiator sizing for water air cooling.

I can give you a rule of thumb based on our expierence so far Don. Something 
like 500 to 800 cubic inches is required. I suspect the thinner the rad the 
lower the volume required to cool a 13B.
