It would be an interesting idea to automatize it to spray when post-cooler air temp reaches a certain level. It would be an anti-heat soak system.
Kyle, would something like this be a lot more effective when it is cooling water, like in your air-to-water system? Its kind of a dumb question because I know water is a much more effective heat exchanger so yes it will, but I don't want to make any assumptions about how the temperature of the water running in the system affects your manifold mounted cooler.
I guess what I'm trying to ask is whether this would be worth the price to develop due to the greater effect it has on an air-to-water system?
