no, i would always opt for the more humid place to get better dyno numbers.
turbo xs had a problem with people complaining about their numbers, so they changed the humidity levels to be much higher than actual humidity and people stopped complaining.

too much water, like completly submerged, will net a loss of power, but vapor like that to make up higher humidity numbers will net a gain of power. its simple chemistry. honestly.

The oxygen in the water is bound, and unusable. This is why you can't breathe underwater. banghead.gif If our engines could cause a nuclear reaction to detach the oxygen molecules from the hydrogen, then damn!

actually jim is right do the reserch cooler more humid air is better for performance. ie water injection the water is denser and so has a better latent heat transfer ability that when it enters the combustion chamber it is evaporated absorbs heat which inturn acts as a retardant like having higher octane fuel thus burning more efficiantly, and provides minor oxygen supply for the cooling effect ie cooler air is denser air.

back to high school chemisty... chemical make up of water... h2o thats 2 parts oxegen for each part of hydrogen. moist air is heavier, which means more dense. which means more air, which in turn means more power. its simple.

Rep Power: 812 humid air is less dense because of the water. but some people think that humid air makes a tiny bit more power because of evaporation cooling the air. i really could care less actually.

Rep Power: 336 well, its humid as **** here in ga. and i know when i breathe in when it is, it does in fact, feel thicker. i mean you can literally feel and almost drink the humidity down here. it sucks. but idk. someone who knows post it up. im not sayin it will make more power, but does humidity make the air denser or not?

Rep Power: 812 over here its usually 100% humidity. you can breathe air in and its like drinking water almost ha. stuff rusts up in an hour instead of years.

you WANT the air to be MORE DENSE because that means there is more oxygen per cubic inch of air.

while you may gain a tiny little bit of power from evaporation and cooling effect, you're still losing much more because the air is not as dense.
no matter what the conditions are, the more humid air is, the less density the air has, therefore the less power to be made.

i knew i wasn't dumb-
Effect of water vapor
For moist air, the partial pressure of the water vapor must be considered as well. In this case, the density of the air is the sum of the density of the dry air and the density of the water vapor:

directly from princeton university:
Most people who haven't studied physics or chemistry find it hard to believe that humid air is lighter, or less dense, than dry air. How can the air become lighter if we add water vapor to it?
Scientists have known this for a long time. The first was Isaac Newton, who stated that humid air is less dense than dry air in 1717 in his book, Optics. But, other scientists didn't generally understand this until later in that century.
To see why humid air is less dense than dry air, we need to turn to one of the laws of nature the Italian physicist Amadeo Avogadro discovered in the early 1800s. In simple terms, he found that a fixed volume of gas, say one cubic meter, at the same temperature and pressure, would always have the same number of molecules no matter what gas is in the container. Most beginning chemistry books explain how this works.
Imagine a cubic foot of perfectly dry air. It contains about 78% nitrogen molecules, which each have a molecular weight of 28 (2 atoms with atomic weight 14) . Another 21% of the air is oxygen, with each molecule having a molecular weight of 32 (2 stoms with atomic weight 16). The final one percent is a mixture of other gases, which we won't worry about.
Molecules are free to move in and out of our cubic foot of air. What Avogadro discovered leads us to conclude that if we added water vapor molecules to our cubic foot of air, some of the nitrogen and oxygen molecules would leave — remember, the total number of molecules in our cubic foot of air stays the same.
The water molecules, which replace nitrogen or oxygen, have a molecular weight of 18. (One oxygen atom with atomic weight of 16, and two hudrogen atoms each with atomic weight of 1). This is lighter than both nitrogen and oxygen. In other words, replacing nitrogen and oxygen with water vapor decreases the weight of the air in the cubic foot; that is, it's density decreases.
Wait a minute, you might say, "I know water's heavier than air." True, liquid water is heavier, or more dense, than air. But, the water that makes the air humid isn't liquid. It's water vapor, which is a gas that is lighter than nitrogen or oxygen. (Related: Understanding water in the atmosphere).
Compared to the differences made by temperature and air pressure, humidity has a small effect on the air's density. But, humid air is lighter than dry air at the same temperature and pressure.
more info:
here's the answer to your question as to "why does more humid air FEEL heavier/thicker when it's humid"
http://science.howstuffworks.com/question651.htm
Ok, so are we clear on this now?
(by the way, i was incorrect on the density/weight thing. density is weight. and yes, more humid air WEIGHS less even though it doens't feel that way)

come on dude, you're smarter than this. dont put yourself into the same circle as these clowns who claim humidity is better because it makes the air more dense.
