Guys used to run them in the past alot, don't know if they really helped, i would say they will if your fuel is getting warm in any given area from its routeing, now if you can cool down the intake useing ice bags just before the run, that'll be worth a solid tenth right there, you'll need to do it in the pit area or back in the stageing lanes somewhere, then push it as close to the water box as possible without fireing it, its tricky doing this as tracks frown on it anymore do to water dripping on the track.
