Sure, an ice setup would be a temporary thing. I've read a few things about that and it sounds like you can run about 10 mins on a 10lb bag on a ~350whp-ish setup in the heat. IATs are well under ambient. A meth setup will probably a hell of a lot colder as you're exploiting the huge energy of latent heat of vaporization.

A normal air-water setup would be perfectly suitable for the street or extended running. The IATs aren't as great, but are in the same ballpark. I looked over some data and you could basically sum it up as the difference between a cold air intake and a normal intake. It's a lot of fabrication, but I wouldn't hesitate to run one on the cars that most of us have.
