more intercooler considerations

http://www.bellintercoolers.com/pages/aachart600.html, e.g. Part Number A600020080, $104. 'Core' thickness is 6", which means that ambient air stays 4x longer in the cooler than for the 1.25" model. As they are only 2" wide a pair could maybe fit stealthily inside the fairings; we'd vent hot air out through the '<' cracks (or whatever they're called).

Although the cross section for a pair is only 0.02mē, i.e. only 20% of what was computed in post #2, I think this could actually be sufficient for an engine generating 50% max power. I'm too lazy to do the math, but 37kw should be able to push a 300kg mass up a pretty steep hill @ 75mph, i.e. a speed still generating enough airflow to keep things cool.

If there are no objections, let's reduce our budget for the intercoolers to $250.
