I have already seen a device that refrigerates the incoming air 
somwhere in a magazine
it does make a difference
if you can keep the air at about -20 you cna tune up to 10% more power 
out of an engine over running air at underhood temps ~150
plus you cna run more comp and timing as well to bump it up a little more

ammonia may work across these temp extremes
but it is not very efficient
from what I can remeber
