So if I went out to my car and fed my 455ci engine a 50/50 mix of water/
fuel I'd get the same power? I have a hard time believing this at full
throttle - plus I cant afford that much water :(, but will it work for part
throttle, ie cruising, speeds?
I think I can get around the mineral buildups with a weekly trip to the track
w/ high octane gas.....

But won't the added water particles reduce the ability to create a complete
combustion?

That much water comes out of my tailpipe?
