The cooling effect is definately maximised when you change the state of the liquid to a gas as most of the heat energy is used to do this state change, however you will still see the cooling benefits at lower than flash point on the water or even water / meth mix.

You also need to remember that the mixture injected into the intake charge is not just to cool it down, it is also used to help 'buffer' the flame front in the combustion process, in effect slow it down a little and make it more controllable. This will help to enable advanced timing and / or less fuel to be utilised and help to get the peak cylinder pressure to a point where it gives the best benefit.

To answer your original question, the intercooler may help, but depending on what compressor you use, what efficiency range you are in with your boost levels, what pressure differential the intercooler will give and thus what the efficiency range the compressor would now be in it may help, or it may actually just put you back to square one.

The other question is, where will the intercooler be mounted, if it is front mounted away from latent heat then you would be ok, but if it is top mounted over the engine you may suffer heat soak during periods of standstill or slow moving. This could be a distinct disadvantage depending upon application.

Also the 100% meth, well depends on the application, the percentage of meth to fuel and how you use the car. As long as you know the meth to fuel ratio and tune the car accordingly you should be ok. Also ensuring that you keep a close eye on all parts of the water injection system for signs of any problems / blockages.
