I used 75M/25W, if you are injecting large amounts of liquid most ignition systems can`t cope with pure water (as has been said above).

For me the higher the quantity I injected the more Methanol I added to the mix (so technically the amount of water injected remained the same), I aimed for 10% to 15% water based on my main fuel injection and the rest was methanol, which also acted as a fuel (allowing the ignition to fire the mixture properly).

You can make great power and inject massive amounts of methanol without having spark blowout issues but it`s hard to tune without having a good system with a proper injector and controller (like the new Aquamist kits). Not really road car/ daily driver friendly at that level.
