more water injection

[jengel at fastlane.net]

Dirk,

The problem is keeping the water mixed with the gasoline.  "Dry Gas"
is generally an alcohol-based product that attaches the water and gas 
on a molecular level (I forget whether gas is polar or non-polar, but 
water is the opposite.  Alcohol has a polar end and a non-polar end, 
so it attaches to both).

I doubt that a significant amount of water mixed with gas would have 
any postitive long term effects on fuel injectors, though.
