Water/meth is water and methanol injection. It's used to cool off egt's and make power. You can run anything from straight water up to a 70% mix of meth and water. Washer fluid is a great daily driver stuff to inject. The colder the rating on it, the more meth it has in it. Normally it's around 20% meth. You can rig a setup real easily. Just need a pump, some lines and fittings, and a hobbs switch. The hardest thing is finding the nozzles that'll atomize the water properly so you don't have big droplets being dumped in.
You can find methanol at almost any race shop in town or at model shops that sell gas powered hobbies. Works great when you need that little extra humpf while towing or racing. I dont reccomend building your own, to much to risk.
