Subject: [FlyRotary] Re: Cooling oil
It would be interesting to measure flow in both engines. I thought that
both Lycoming and Mazda engines rejected 2/3 heat load through the
oil that is why I started going down this road. If the engines generated
the same Hp than the heat load should be similar.

Joe, both engines may generate the same heat load, but the proportion
rejected through the coolant in case of the Mazda is 2/3 of its waste heat
while the oil rejects another 1/3 of the waste heat. Neither engine rejects
anywhere near 2/3 of its waste heat through the oil.
Most aircraft engines reject on the order of 300-600 BTU/Min through the
oil, the Mazda at 160HP rejects approx 2446 BTU/Min through the oil.
