It's there, but just in a strange way.

I should have guessed you were planning another rear-mounted turbo setup...

My Vaz gets better MPG in the rain. Probably due to it's swirl-type combustion

I'm not sure if the swirl-type combustion chambers should be affected in a different way to the higher humidity at the intake air stream.

It might get better MPG in the rain from lower rolling resistance, or a number of other factors. |

I have found that O2 extenders fool the O2 into showing leaner than what's really in the pipe and add more fuel, actually makes the vehicle run richer.
Or us them to fool the rear O2 after a catalytic converter delete.

A few days ago while I was walking around the neighborhood I noticed the amount of water drained from the air-conditioning of a small bus at a stoplight. It does seem like a waste that it wasn't reused into some water injection system, since it could eventually at least overcome the fuel-consumption penalty inherent to the air-conditioning.

A self-perpetuating evaporative cooler (wink,wink)? |

Well, sort of. Since the water would evaporate either in the intake stream or during the compression stroke while retaining latent heat and decrease the heat irradiation through the cylinder walls  |

I had a 2001 7.3 diesel and if it was raining or better yet missing, my truck would run like it had two turbo's. It was amazing, I did notice on my wife's Colorado, it runs better when it is raining or misting. I think it is because of the added water grains in each intake stroke.
I have always wanted to add some kind of water injector upstream of the sensors and make it so I could turn it off before I shut the engine off to clear the system of any extra water.
I still feel with the right set up it would help and improve both power and fuel economy.
