Ferrari in 1983 used water injection for their F1 racing engines. Interesting how this method has been banned in F1....
Fun Facts about Water:
*Thermal Expansion is 1700x original volume when heated to 212 degrees F. (Vaporization)
*Thermal Expansion is 3400x original volume when heated to 424 degrees F. (Vaporization)
-Imagine what this does to the expansion and pushing of your piston head-

-Decreased engine heat and header temperature
-Maintained combustion inside engine (Water Expansion Ratio)
-De-carbonize of engine valves (Cleaning)
-Potential MPG increase (Testing needed)
