Well according to this there is still a possibility that things can happen. At the end of most CAI there is a bend that points up to move the filter farther from harm. If you submerge this then there will be water left in that U. If this article is correct you can suck up some of that water once the U becomes unsubmerged. There is always a risk, but this is better than no valve.

I think that's a bad conclusion to draw. This was with an engine that had much stronger intake needs than it was even designed for and with them really trying hard to push the engine way too hard for the type of conditions that would completely submerge the intake like they were doing. I'd say the conclusion is that with this in place, the likelyhood of a problem is pretty much nil.

yep

 

i still dont see why our cars would need this... you would really need to completely submerge an intake to pull that water up in the intake, correct? Also we are not driving some hondas that are slammed on the ground... we would have to drive through like a foot of water to submerge oru filter... just my .02

 

the fact that ive heard of so many cases of ppl having a bypass valve and hydrolocking totally discredits this article in my mind.

 

From experience, when I was aspirated, I had an Injen CAI and no bypass valve. This was during the FL summers with torrential rain during the afternoons. Nothing happened, even tho at times the filter was completely soaked, with water dripping off of it. I think for hydrolocking to occur, that complete submersion is necessary. The whole cutting my intake pipe thing after I spent 2 bills really didnt appeal to me, and up until I took it off, I had no intake problems.

 

I had to park my car during the Hurricane season to avoid hydrolock. Half the car was going to be submerged in this one parking lot I was in. I did not have the bypass but let me tell you that my filter somehow got wet when mitsu washed my car one day. I left after an oil change and I floored the accelerator to make sure things were ok and the car sucked up some water that had somehow gotten into the intake piping. I had no idea that the filter had gotten wet but after popping the hood to examine things I saw the filter was wet.

Neilschelly you are quite incorrect.

Come to think of it I don't know how the hell you can wash a car and get the top side of the engine bay that wet unless you were intentionally trying to.

That's a little unfair. I said the article basically concludes that you'd have to really try to hydrolock your engine, that it's not gonna happen by accident, and that the valve will prevent the accidental stuff from being a problem. You seem to be drawing the same conclusion with your statement above.
