Well, I have been given contradicting information on which is better for knock and performance. For what it is worth this is what I have discovered:

(1) US and German military planes used water and methanol injection on planes -- 50/50% ratio (I am guessing they experimented a bit...)
(2) Adding 50% water makes the mixture less combustible / more safe
(3) Water is reported to cool the cylinders better than Methanol
(4) Many tuners prefer 100% Methanol (not sure why) and believe it yields more power
(5) SMC (the maker of my kit) recommends 50% water...not for seal issues, but for performance

I figured I would try it for myself and see if it yields better results....
