a mechanic mate of mine back home ran his car using water injection.......it was a 1975 XB Ford Falcon GT. Don't expect you to know what that was, but you can look it up using www.anzwers.com.
anyway, he was getting around 35mpg from this "dinasaur" 351 Clevland engine
besides....I saw the documentry on the waterpowered car I mentioned above.....did you?
Stretch, I'm 69 years old. I am a retired mechanical engineer.
I know what a Ford Falcon is. I also know what water injection is......It is not water used as a fuel.
The "documentary" on the water fueled car was a complete hoax....nothing more.
