hi, did you consider E85 fuel? it is like half a way to water/meth. I use to use it (before lpg conversion) and i was very happy with it. Same setup and ~ +20hp just by using different fuel.
It has very good cooling effect too, very resistant to knocking (allows almost ideal ignition timing) and it is quite available / cheap in my country.

That is a shame, supporting E85 it is like one positive thing on eco craziness here in eu
For water/meth what about using normal kind of fuel pump + fuel injector? Some kind of fuel pump used to have pressure regulator build in and fuel injector can be controlled simply by switching battery voltage on it.... just idea.
