I see alot of people get the by pass valve ofr there intake. What does it do and does it make the intake more restrictive?

 

search is your friend

 

but just to answer it is not restrictive that i know of....
the use of it is to eliminate hidrolock

 

The way I understand it, a bypass valve is installed to prevent a CAI from taking in water if it for some reason, the filter element gets submerged. I don't know how it works or if it's restrictive, but according to doctorimport.com,

That doesn't help me imagine how it functions. If somebody could state this in plain ol' american (AKA dumbanese) or even better, provide a diagram pic, that would help.

 

Yea, I live in michigan where there can be a lot of precipitation so i think im going the bypass valve. Also I was wondering if anyone knows anyone here that has experienced hydrolock and what exactly happens.

 

Engine go BOOOOM!!!

About 10 years ago, my mom had an 80-something Volvo and decided to follow this 4x4 through about 2-3 feet of water. Well, on her car the intake was real low, behind the front headlight. Needless to say, sucked a bunch of water into the engine. Since water can't compress like air, bent the **** out of the rods and valves.

You may as well buy a new engine when this happens.

 

I think it was seen before though, hydrolocking will only occur if the filter is complete submerged. I also think someone said it was very rare

 

never seen it first hand here in texas, and trust me ive seen some crazy ****. (woman complains of a smell in her lincolin town car, i find a dead calf in her trunk so infested with maggots we had to call the company that cleans out ambulances to get it out)

 

Is it possible to install an air/water bypass on the RRM cold air intake?

 

nope, the rrm one is a one piece, the bypass needs to be installed in between two pipes like the injen one....i guess if you really wanted to you could cut the rrm one in two pieces and install the aem bypass, havent seen that done though.

like someone said earlier about the filter needing to be completely submerged to hydrolock, thats true. the intake has to pretty much be sucking up all water and no air to hydolock. you might stall in some fairly large puddles, but not hydrolock.

as far as restrictions, i heard awhile ago that if you put a bypass on, it reduces the performance of the cold air to the performance of a short ram. i can't see the truth to that but it probably does give the cai some restrictions.

 

again a short ram produces more power than the cai as long as you dont have heat soak

 

mitsutech could u elaborate on that? A SRI produces more power as long as u dont have a heat soakeR?

 

The bypass isn't restrictive. The only downside is that it creates a touch of turbulance in the intake pipe.

The way a bypass works is really simple when you see it. If the vacuum becomes strong enough in the pipe, it pulls open some flanges around the perimeter of the bypass, letting in air from there, instead of pulling it up from the CAI.

This is a recent topic.

 

i dont think you really need it. i have went through deep water before and i even cut a hole near my fog light to allow for air flow in and nothing happened yet.
If you want my info about the bypass valve go to the aem website. they have a video of the bypass valve in action.
