Good points, all. I do not remember reading about any "optimum" temperature, as such, but pre-ignition / detonation are things to steer away from.
Preventing overly hot temperatures was one reason I went with a heater core-based heater, as opposed to an exhaust manifold-based heater. It'd be near-impossible to get 300 F out of coolant (and if you're getting that high a temperature out of coolant, you've got other issues...) Another reason was that it was easier to route coolant hoses than it was to route air hoses.
As for the actual temperature? Your guess is as good as mine. I do know that my truck seems to love 130 F as its intake temperature. I would go higher, except that might start wandering into pre-ignition / detonation territory.
