Spearco water injection?

[cdhd2001]

Have any of you guys used a water injection system?  The only two I know of are aquamist and spearco.

I am familiar with the Aquamist system and the Carroll system - they both work fairly well - note that Whipple maintains that you should not put the spray through the compressor which is where you really need the cool down.
