Dry Ice is Carbon Dioxide (two oxygen molecules). You may be thinking of Carbon Monoxide which does attract another oxygen molecule.

Truthfully, though, no one there bothered to go through the trouble of trying it and doing before/after dynos. I'm sure we could all learn something if you want to do the work...
remember that at WOT the compressor is shut off (clutch disengages) on alot of vehicles...so the pulley just freewheels

depending on acumulator capacity it could provide cooling for ~15-30 seconds, also remember the Ford lightning trucks are factory supercharged with an air to freon intercooler that would provide ~20 seconds of cooling...

yeah air to freon intercoolers work and make appreciable power but of the few setups i have seen the turbo discharge went through an air to air intercooler and THEN it went through an air to freon setup (with extra accumulator capacity) and the air temps entering the intake werent that far above ambient and the one vehicle was pushing 28psi. before the air to freon intercooler he maxed at 20 psi with no detonation (2 stages of direct port nitrous as well )

granted the 3 vehicles i've seen two were imports but the third was a heavily modified lightning...

properly engineered air to freon intercoolers work...but they work better when ther is an air to water or air to air intercooler plumbed before it.

this is a system i am looking at running on the rear 3800 in the 442, thats how much faith i have in the design.

in reality a 25Hp shot of nitrous would provide the same amount of intercooling...as well as adding power.
