<VV> Descending a mountain

[Mark Durham]

Boys, boys, the ambient temp drop as you climb enhances cooling, and
since the air is thinner, the engine cannot produce as much power/heat,
so nature automatically compensates for the extra heat from the climb,
just make sure the build is right and go drive the things! the best
thing you could do is to leave the rear doors or the complete lower
shrouds off in the summer which will more than compensate for the extra
heat in a climb.

Well, the weird thing here is...  for every 1,000 feet of altitude, the temp
drops 3F degrees.  So, as you go up the mountain the engine will be working
harder (than it will later - downhill) and the ambient temp will be
dropping.  So, depending upon how steep a slope you just climbed AND the
altitude you are at AND you could probably throw in the lower barometric
pressure to the equation (less air to mix with the gas), it might be wise to
find a wide spot [Overlook?] and give yourself and your pretty pickup truck
a 15 minute break before proceeding on.
