efficacy of distilled water vs. distilled water & alcohol mixture or which is better over the other. Lots of questions on this end to be answered.
distiled water and alcohol is better. The alcohol increase the octane and allows for more boost. Alcohol also evaporates faster than water so it cooles better.
If you have an intake temp sensor you can measure the temp difference between when you are spraying and when you are not.
From what I understand all water/alc injection does is lower the intake temp making it more dense. More dense air in the engine means you can add more fuel. Very similar to putting on a large intercooler. If you add alc you also increase the octane again allowing for more boost.

If it helps, it was 100 F today and my intake temps were 75 F.
Also, I run a bar on the street in crummy CA pump gas now.

Hello no.
I have a unique DIY system, but I believe that AQUAMIST knows what they are talking about. They do NOT recommend prior to the IC at all, and they recommend prior to the turbo on for race applications.
They said that if you do prior to the IC the air going in the IC will be cooled to a point that the IC has no effect, also something about the volume of air being used by the turbo could be negatively affected or something.
I have a dual stage set up. I have a very small Blitz SMIC that has a small 1 GPH nozzle attached to the end tank, and I have a 4 GPH nozzle that is located in the elbow right before the engine. inside the elbow is an extension that goes down about 1.5 inches and has a 90 degree elbow attached to it. An injector is attached to that. The result is the mist is sprayed down the elbow towards the IC in a very fine stream (you should see how fine, its amazing). this stream evaporates immediately, before it goes in the engine.

your probably right. The alcohol also helps keep the water from freezing in the winter.

I have been looking at those for some time. Best deal for the performance. I figure I should be able to afford one in about 50 years.

Just noticed the European plates. Never mind
