Water/alcohol injection is very effective in cooling the charge and offsetting knock.
The reason I won't use it is compexity. It is one more maintenance item that I also view as a bandaid. It is optimal to have a system that requires no consumable fluids, electric motors, or added complexity. Air-to-water intercoolers suffer the same complexities as water injection.
An air-to-air intercooler is by far the least compex and the most maintenance free. There are several cars on this board with no-tail intercoolers that can be used for ideas on how to do it, unless you just plain don't want an intercooler.
