Humidity and CAI?

Would high humidity affect a Cold Air Intake at all?

If it it really hot out your CAI will not work nearly as good. On hot days my cars acceleration use to suck compared to when it was colder out.

Cold dense air is the best. Hot air sucks! thumbsdown

humidity does affect peformance--INDIRECTLY.

the only real thing that matters is whether or not the air is hot or cold.

hot air has the ability to hold more moisture, thats all. cold air holds very little moisture and sometimes none at all. just because air is hot though doesnt mean it has to be humid..there has to be a water source present for the air to 'suck' up that moisture (sorry if this is confusing).

like i said though..the only thing that matters is whether the air is hot or cold. to go a bit further in details..it's only OXYGEN that really makes a difference. the more oxygen you can stuff into your engine the better it performs because it will mix with more fuel to make more power.

hopefully this can explain what im talking about: basically..hot air is bigger (if you heat air, it expands and the molecules are spaced further apart). cold air is dense (if you cool air, the molecules cluster closer together). air is made up of about 18% oxygen. that means for every 100 molecules of miscellaneous air molecules, 18 of those molecules will be 02.

now, think about your Intake manifold (Intake). it has a fixed volume--it only has so much space that air can be transferred to the engine in, no more, no less. so obviously if the air is colder it is therefore denser and therefore more air can fit into your Intake which therefore means more oxygen gets into your Intake which therefore means you can burn more fuel which then makes more power. the opposite is true of hotter air (hot air means 'bigger air' which means less can fit into your Intake which means less oxygen gets into your Intake which means less fuel is burnt which means less power)

ah, i'm gonna shutup now. i'm sure i confused enough people with that but i hope you got what i was talking about thumbsup

yes. thanks. i guess i'll consider a CAI now. wasnt sure if the moisture of the air would be sucked in or not.

^^ yes, the moisture will be sucked in...but humidity is humidity no matter where you put your Intake. just because you have a CAI doesn't mean NOW you will be sucking in the moisture--even with a shortram or stock setup you'll still be sucking in the humidity.

BUT..good thing it doesn't matter wink thumbsup just keep away from deep puddles and obviously flooding.

after i put the CAI in my GT i started to notice that the perfect temp was right around 73*f, now that i put my new exhaust system on there seems to be a wider range that i get great acceleration.

generally speaking, the colder the better, the drier the better
