Most real spray kits use compressed nitrous. Since dripping water on the track will get you disqualified, it is a good method because not only will it not drip, but the nitrous is extremely cold.
I don't really know if it is worth it, though. I haven't seen any dyno sheets that confirm it will significantly increase horsepower.
