Thanks very much Steve
So very helpful.

I=E2=80=99ll check if I can fit one of these Fluidynes in place on =
Friday.

Yesterday I spoke with a local expert rotary racer of 30 plus years here =
in Perth.
He has used Mocal coolers for many years and recommends them.
http://www.mocal.co.uk/products-oilcoolers.html
I would like to have a comparison between the Mocal and the Fluidyne.
Be nice to hear if Lynn E has any experience with the Mocal units?

Mocal -     13 x 13.5 x 2 inches - core volume 250 inch2 single pass
Fluidyne - 9.25 x 14.75 x 3.125 inches - core volume (estimated) 320 =
inch2 dual pass

The Mocal cooler puts the in/out fittings in a better orientation for =
our application.

Cheers

Steve Izett

There are removable flanges 0.75" wide along the top and bottom of the =
11.5" long core which makes the unit 10.75" high if they are left in =
place.  There is a 1/2" NPT bung that protrudes 0.75" from the top of =
the end tank.  The AN12 male connections were 2.5" from the top or =
bottom of the end tank and parallel with the long dimension.  All these =
connections are on the same end.
