Here is the rule: (THANK YOU JERRY MOUTON!)
"...As utilized only on engines originally equipped with forced
induction, air-to-air heat exchangers (known as "intecoolers"), and
radiators which are part of air-to-liquid charge coolers, must be cooled
only by the atmosphere. The use of chilled liquids, ice, dry ice,
refrigeration systems, vaporized compressed gases, etc. is
prohibited..."
This appears to me to cover both on grid and during the run. It may not
be what the rulesmakers intended, but it looks like a good case for a
protest...
