Charging ?s

Anyone with experience using water injection with supercharger? I've mentioned previously I am going to get the JRSC, and i'm wondering if i will need water(or 50/50 water/alcohol) too cool things off if i want to use the 9lb. kit. as i live in cali, we've got 91 octane supreme(sucks) and i'm looking for long-term durability(as much as possible, anyway). is there anyone out there using the vortech set-up? any help is appreciated...
