Just throwing something out on this from looking how my stock Neon is cooled. It has one electric fan, and a shroud. On the shroud there are a lot of windows with a rubber flap. At low speed the fan does the cooling, but at speed the fan stops, except when the a/c is on, and the wind pushes the flaps open and that does the cooling. I'm sure this concept could be useful at the strip also. Let the fan do the cooling in staging, and turn the fan off, then let the wind cool during the run.
