Here are some pics of the custom oil cooler for my 20B built by

Griffin.

It

is a very nice piece of work, and very heavy duty (also heavy, 10

lbs) -

designed for 125 psi operating pressure.  The core is 20.5" long, 5"

wide

and 3.34" thick.  Internal turbulators in the wide tubes also hold

them

together; they are brazed in.  14 fins/in.  Design point is 1600 cfm

air, 16

gpm oil, 220F oil in, 90F air in, resulting in heat rejection of

Btu/min.  Good for 220hp continuous on a hot day.

Looks beautiful Al!  If you don't mind my asking, how much did this gem set
you back?
