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.

these are not high capacity units

Re: Fw: Water temps
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 below..........

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?
