@RobertS.Barnes - Realistically I don't think it's going to help much. Remember, with a water/meth injection system, it's on top of what is normally injected (or carbureted) into the engine. With what you are proposing, you are going to have a mix. Knowing the alcohol, while having a higher octane rating, has less specific energy than gasoline and water has no specific energy (as compared to gas), I think you are going to run into a huge lean condition with your engine.
