Custom Liquid Nitrogen Cold Air Intake..pics to come soon...

Spraying the IC isn't a very efficient way to cool the intake air. Think about what happens,
the spray comes out and is carried by the local airflow to the IC face. Right there the CO2 is cooling the outside air, not the stuff going into the engine. Once it reaches the IC it starts to cool the outer surface, which eventually will transfer to the inner surface getting cooler. The inner surface of the IC being cooler than the intake air is what will cool the intake air.
If you have something directly in the intake air path that is cool, it will be more effective at cooling that air. I see this on my car with IC sprayers and water injection. The water injection goes directly into the intake air and cools much more effectively than the IC sprayers can do.

Drag racers have had amazing results with liquified gasses sprayed on the ICs.
At least some of it has to reach the IC metal in liquid form and boil from there or you're wasting your time.

I'm sure every bit helps, but if the point is to cool the intake air as much as you can,
then it makes more sense to cool the air directly than to pass through another medium, metal in this case, before beginning the cooling. I was trying to make that point to the person who suggested that spraying the IC's with CO2 was the best way to cool the intake air. I'll ice down my IC's before a dyno pull if I can, every bit you can bring the temperature down helps.
