Next time you are at the track, take your infra-red and measure the tarmac temp. 
"I'm going to build a ram air system for my Cobra, but since I can't figure out any other way, I'll just pull in the hottest external air I can find and call it a day." 
I had an idea for you - what about putting an air to water heat exchanger in your lower air intake tract and cooling the charge much the way Ford cools their inter-coolers.
Please share what "out of the box" thinking you see in Johns car?

I gather that your (and Carroll's) contention is that tarmac temps have a direct correlation to the surrounding air temps. It looks to me that we would first want to actually measure the air and see if there is any validity in the assumption. Assuming that we validate the assumption with a significant measured temperature gradient above the tarmac, we would then want to measure whether the mitigating factors such as cross winds and traffic turbulence have an effect on the temperature gradient. Assuming we do, we would then want to measure static temperature gradient recovery times (i.e. how long it takes for the air to reheat once the traffic is passed or crosswind stopped). Does this sound reasonable to you?
