I have the A43-330
MoCal. Plumbed on the outlet of the rad where the coolant temp may typically be
160F at high power and the oil temp (at engine out) may be 220; and it handles
roughly 30% of the oil heat load on the 20B.
Be aware that this
cooler; like any off-the-shelf unit, is designed for the lower oil flow rates of
piston engines. I’d not recommend plumbing this for full flow from the rotary
unless you are willing to accept 20-30 psi pressure drop.

I did not see an
answer to your question about "Mocal" water to oil coolers...............It
has been
reported previously that some have
used the "Mocal" model A43-330 cooler with
success........
Some have had custom
units built by Ed Klepis at "Tech -Weld" or other
suppliers........... I have
had a 330 for some time but alas I
am still grounded !!.............<:).........See PDF

[FlyRotary] Re: Fw: Water temps
This is where I
get confused:
-ideal water temp
= 160*~180*F
If we are cooling
oil with water that is at best hotter than the ideal temp of the oil, then
are we not adding heat to it rather than removing it?
If we are trying
to cool oil, why would we feed the highest temp water to the oil/water
cooler rather than the coolest temp water by tapping into the pump housing
where it enters the block?
Based on feedback,
the water entering the block may be as low as 150*~160*F, would this be cool
enough to do an adequate job of cooling the oil?
Also, which model
of Mocal is being used?
