Tom, the tests were run from a dive and I waited for the aircraft to slow to a constant speed. There was no overheating when temp effects were on, as of course there weren't with temp effects off. The loss of speed wasn't due to overheating being the cause of a power loss. Temps were normal but rising fast. The Spit had already slowed down to 270 well before 120 degrees on the rad temp, or over 95 on the oil, in fact on the second screenshot, you can see that the rad temp is about 110......
