   Hi Paul,
    Once again a superb job. I seem to have lost the email about the
size of the heat exchanger  for the water cooling, Do you have the cubic
inches per HP that is required?
     Andrew Campbell.

We used to think it was 600 cubic inches for about 250 HP  but recent experience maybe
500 is more like. A lot depends on how it is installed. A good wedge
diffuser is essential.  Do you have my book?
