Thoughts on water injection for increased MPG

And you have to have a tune for it to be effective and see maybe 15 or 20whp from it. Without a tune it has the chance of messing up your engine. And we always ran 70/30 mixer. 70 parts water/ 30 parts methanol...Or a full gallon of windsheild wiper fluid that is 20* and under is a 60/40 split. so you would either mix in some water or find a place to buy methanol.

I know it's purpose in a forced induction setup, but you fail to see we are discussing it in relation to a Naturally Aspirated gasoline engine setup.

Just remember that if you had read the entire thread this info would have been mentioned previous to your condescending, high and mighty post

Not trying to be a dick or anything, but you kinda started it

Not sure how much this relates, but one of the professors at MU's ag department did some research and developed a product that allowed water and diesel to become emulsified and thus burn up to something like 50% water in a diesel engine. This was tested in a mechanical injected diesel engine and emissions and power significantly dropped fuel consumption remained about the same.

Regarding this in the same sense that water takes up space in the cylinder and is not combustible I imagine the results would be somewhat similar in a gasser. Higher compression, running cooler, same fuel consumption, less power. But a dyno test would tell for sure.
