Of COURSE the car is less-peppy with the oil at around 260*. The engine is quite obviously heat-soaked. Why wouldn't you expect to lose 10whp or so with the thing heatsoaked?
I will FULLY admit to have not read that full thread, however, please clue me in: Are they any engine failures traced to lubricant over-heating with the 370Z?
