Water ingestion from air intake? not convinced

The point is...Op was talking about water coming in through the airbox...weather or not it has 15 feet of intake plumbing or not...all should suck in water from the airbox...N/A or not

NA - like putting your mouth over the glass and inhaling
Turbo - using a straw
Hope you get the picture, seems like a good analogy in my head ;-)

I am still skeptical about this though because the air filter would be wet and to date I have not seen any posts claiming that the filter was wet.

Like already said, water is coming into the intake, only it's in a gaseous state. The only difference is the intercooler condenses it and holds onto it for a while.

Well, maybe. Depends on the volume of air and size of the passage because really, it is all about the velocity though I do agree that if it were small amounts of water coming in through the intake it might be little enough that it does not affect the NA engines but it pools at a low/slow point in the EB until the velocity of the air increases enough to introduce a large slug of water.

Usually does when you're 10 deep into a 12 pack. Regardless of how a motor makes it power, the air needed to make the same amount of HP is constant. i/e a 365 HP NA motor breathes the same amount of air as a 365 HP turbo motor. At least that's what makes sense in my head Like already said, water is coming into the intake, only it's in a gaseous state. The only difference is the intercooler condenses it and holds onto it for a while.
The NA engine doesn't have the suction a turbo would so it gets to drain away.
I don't recall anyone checking their filter to see if it was damp after an episode.

Wouldn't the water be atomized as it is sucked in via the airbox? And wouldn't the volume of air flowing through the filter dry the filter out very quickly? Yet, you could still have air with the maximum humidity now going through the IC and condensing where it could now settle and be gulped at WOT. Just making guesses here, but then water ingested into the airbox would exacerbate the problem. Or maybe this was just an opportunity to use the word "exacerbate."

Love My Eco
Ive never had either problem, though i've never checked my IC to see for condensation, how would i go about doing that. anyways, my tuner is working fine, i'mgetting normal gas mileage, with no shutter, no st-udder, no loss of power, its been running normal for 28k love my Eco

As for water atomizing, maybe (sort of) but only if the air is not saturated as it passes through the airbox. If it is saturated, it cannot pick up any more water.
Either way, the water entering the system would be in vapor form, not droplets.
I still think it is a case of saturated air entering the system (not air being saturated by picking up water in the filter box) and condensing in the system. Light throttle means lower air flow to the engine, highway speeds means high flow across the outside of the coil. Add in rain or fog and now you've got a wet surface on the outside and evaporative cooling transferring even more heat away from the air inside...that would raise the potential for dropping the intake air below dew point. It appears the intercooler is too effective under those conditions.
