Has anyone used water injection to replace intercooler?

I like the Autospeed Intelligent Intercooler Water Sprayer. It uses two temp probes and a mini computer to allow you to adjust based on differential. I bought one, but have not fully installed it so I cannot provide any complete experience. There are a series of five or six articles on this kit at the Autospeed website that are worth reading. There are also a couple of unrelated articles on water spray in general that conclude it does not help during a dyno run or drag run, but that it will help get the IC back to normal temp in prep for its next run. On the dyno or dragstrip, the IC needs some heatsoak ability (which older Spearco IC have, but newer lightweight tube and fin design IC lack) and airflow. C02 or nitrous will help on the dragstrip or dyno.
