Re:Simple Question
 

its only common sense..... when it rains there's usually puddles and you hit them all the time! when i wash my car and it rains when i'm driving, usually if you open the hood the engine in not dry ::) water goes everywhere when you're driving and especially when the turbo sits low near the bottom of the block....water is definatly going to splash on the filter of the turbo. thats just what i think. so it would eventually ---- up the turbo right? yeah, im using the k&n filter but i was just curious cuz the k&n wont stop big slashes directly on it....some water would still go through right?

Re:Simple Question
 

if you use a bypass valve on your charge pipes you will never enter boost..

common sense (but correct me if im wrong)

Re:Simple Question
 

(correcting you because you're wrong) :P

It will allow pressure inside the pipes. It only opens if the intake is plugged. I have no idea how to explain this, but it will work. The pressure(boost) will keep the flaps closed on the bypass valve.

Re:Simple Question
 

corrected, but wouldnt you leak boost?

Re:Simple Question
 

To my knowledge, the bypass only flows one way. Air can get in, but not out - but I'm not t-totally sure on this point. Call AEM if you really want to do this, altho I think it is pointless.
No, it doesn't help with splashes. It only opens if the filter is restricted (dunked) enough to create a vacuum which will open the valve. Splashes aren't what hurt your engine. Moderate rain shouldn't even pose a problem really (like if your hood was missing). You need enough water to completely cover the end of the pipe before the engine creates enuff vacuum to pull it thru to the engine, otherwise it is just going to run back out or puddle while the air rushes past it IMO.

Re:Simple Question
 

Agreed. This is why it wouldn't leak boost. I'm not sure how much boost one of those things could hold so that might be the downfall. :-\

well, i wasnt saying i was gonna put the aem bypass or anything like that on my setup....i was just curious to see if it would be enough water to cause damage to the turbo,...of coarse it would ---- up the engine.

I am now dumber for reading this... thanks.

Re:Simple Question
 

lol...

I have never seen a cai bypass valve with a "flapper", they are usually (at least the ones I have seen) basically a connector that can breath air (made of foam). If you submerge the end of your CAI in water, the vacuum will suck air through the bypass rather than sucking water into the engine. The bypass valves I have seen would definitely blow out if they saw boost.

this is pretty pointless though, there is no need to have a bypass on a turbo system. Just don't stick the filter 3" from the ground.

Re:Simple Question
 

thats what i thought also.
