On a hot day the temperature coming out of the compressor could be close to 400 degrees at full fuel flow. There is a temperature sensor on the intake manifold. I assume that if temperature became a problem the DDEC would dial back the fuel flow. As far as mechanicals go the materials can handle it on the output side if they can handle it on the input side.
Jon, checked with ddec 3 expert today, and he told me hyd radiator fan is controlled by cooling water temp and intake manifold temp., and will derate if either temp is too high.
This makes sense as I also noticed cooling water temps remained low, suggesting fan was running all the time. Will clean cac and test again.
