Maybe construct a ram air of metal pipe and run the coolant hoses around it to heat it.

Now my question is, how much positive PSI acts on a car's front bumper at 60-65mph? Anybody know?
Don't know the answer but I have been tempted to get hold of an airspeed indicator from an airplane or even a magnahelic for live pressure instrumentation while driving. Accounting for airspeed would be a cool part of information gathering.
