in short the answer is yes, my mate used to run a drag Scooby at Crail alot, when it was warm the Fire Extinguisher was cracked out and the FMIC got a good long blast.
TBH tho, its not goin to make much difference on a standard car, that said the TMIW (top mounted interwarmer) would get flushed with very hot air waiting in the queue and then on the line, so it might make a difference after all
P.S. Make sure you dont get a foam extinguisher...... its not pretty
but its VERY VERY VERY funny
