My friend and I installed a water/meth kit from Alcohol Injection Systems the other day. It is hard tell if it has made the car any faster (it's hard feel a couple of tenths). But it does however make the intakes much cooler to the touch. After several hard test runs the top of the intake manifolds were warm but not hot and the back of the intake runners where I installed the jets was room temp at best.

And Rodney at Alcohol Injection was very helpful. He set the system to come on at 9 lbs of boost via vacuum. I will be going to the track again on the 12th of this month to see if there is any improvement to my best of 12.87 and 108. Here are a few pics of the install.
