This is something that has been bugging me for awhile. I have a 400E that is very sensitive to intake temperature. The cooler it is outside, the faster it goes. I have had a couple dozen cars over the years, and none have ever been so profoundly affected by intake temp.

I have an evaporative cooler in my house that cools the air temp at least 25 degrees. And it moves 7500 cubic feet of air a minute! Why wouldn't this same concept work for a car? Understanding that getting the right air to water vapor mixture would be tricky, it seems to me that compared to all the complexity of turbos, superchargers and NOS, a water vapor system could be done very simply and for low cost.

But - not being an engineer, I am sure there are some good reasons this kind of concept hasn't been pursued. One thing I can think of right away is that most parts of the country are already humid, and adding more humidity to the intake air stream wouldn't work very well. But for those of lucky enough to live in low humidity climates (Denver.) it seems like this OUGHT to work?

Any feedback or ideas from the smart folks on this forum?

Thanks -
