Disclaimer- I am not a chemist, well I may be a shade tree chemist.
What I have found:
50/50 Water Methanol will not burn.
Water chemically bonds very strongly with methanol.
Nitromethane kinda stays in suspension in methanol.
Water, added to a mix of nitromethane and methanol will bond with the methanol strong enough to displace the nitromethane.
You can mix (and it will stay mixed) water and methanol or nitromethane and methanol, but never water, nitromethane and methanol. (the water bonds too strongly to methanol)

Straight methanol is wicked for injection intake air temps, but will richen the A/F mixture.
Water cools the intake charge less than methanol, but suppresses detonation better than methanol.
Water methanol is a great combination.

Nitromethane burns at 2.5 units of air to 1 of nitromethane, because it creates oxygen when burned.
Methanol burns at 8 to 1.

A 40/60 nitro/methanol mix injection actually leans the A/F, but stops detonation as well.

Internal engine parts do not like nitromethane...
Spark Plugs go quickly with nitromethane, engines can go from too much raw liquid in the combustion area, or from too much power being made.

Nitromethane is very fun, but costly, no more so than Nitrous Oxide though.
