I would run pure methanol for the cooling. But I run at least 25% water for detonation deterrent. Since it's cold, I've gone up to 50/50.

water is a much better heat absorber than methanol. The methanol does give a slight octane boost, and adds additional fueling since it burns (which may or may not be an advantage), but for pure heat absorption go straight water.
I had a procharged 540 without an intercooler and straight water injection, made over 800 rwhp with our crappy 91 octane. The stuff definitely works with or without an intercooler.
