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?

Paul Lamar

    Yes I did have your book but I lent it to John Shuttleworth who is
no longer with us,  I do have the emails and photos of the diffuser that
were posted here.
    Thanks that gives me a good Idea on the size required for my 130 HP.
