I'd go with that. My experience, particularly on the V8, is that the gauge
goes up
after a high-speed run, then comes down again if the speed increases again.
Indicates that the cooling effect increases faster than the heating effect, at
least
for 'normal' highway speeds. I suspect that, the V8 in particular, would have
a
cross-over at some point, the energy required (and hence heat generated) to
push the
car through the air increasing exponentially or whatever.
