i just put cold air intake on my teggy w/ new filter and breathers but there isnt any cover for the filter like how the stock one is....it was raining today and when i parked up there was a line of water running underneath my filter which could touch it from driving....

if the filter gets wet can the engine suck in water from it and create damage?

 

i belive its called hydrolock but im really not familliar with it. i hear its one of the big problems with CAI but just wait for someone else to come along and explain it better.

 

yes its called hydrolock and in theory it only happens on rare occasions but ive heard many stories of people hydrolocking. it affects mostly with people who have cold air intakes (which is why im against them). obviously water getting into a cylinder is NOT a good thing.

it should only happen if the filter is completely submerged and you decide to go WOT for some apparent reason BUT my friend hydrolocked his civic when he was doing a turn and went over a big puddle.

 

yes if the filter is wet your you can get water in your engine. and if that happens when your driving hard, or even just driving, kiss those pistons and rods goodbye.

 

the filter getting wet is not a problem, problem is when filter gets submerged in water, when at the air inlet there is not air to ingest so water tries to do the job.

 

75 foot skim of 6-8 inches of water, CAI, 1st gear @ 750rpm idle, one ruined weekend...

Remember, if you hydrolock your engine and it shuts off, don't attempt to restart it untill you pull the spark plugs out and then turn the engine over to shoot the water out! I run a SRI now, Florida has too much water on the roads.

CAI's are not worth it, IMO. If your putting down serious numbers or racing where every single hp counts, thats one thing. But for a daily or even weekend driver, why chance it?

And if your talking about the valve cover vent, its better to leave that on the intake arm unless you have some type of Crankcase Ventilation setup.

damn dude that sucks, i feel the same way, nothing but a SRI on my DA ive seen headgaskets blow because of this too.

 

using a breather is also not recommended

 

dude I have a DA with a CAI and no splash shields underneath(how I bought it) and totally forgot about it when it was raining and went thru a puddle.
Go thru it, try and get on it about 3000 rpms and it falls on it's face, oil lights on car shuts off, white puff of smoke.
Oh damn. So then it hits me that I just drenched my CAI and I most likely just hydro locked it.
Luckily that wasn't the case, I just unloosed the tube at the tb and got to work and dried out the filter.
I'm thinking I need to change mine out or just shorten the tube and short ram it. I had just swapped out the bottom end for a newer b20z too so that would've sucked major *****.

 

WELL, for those with a CAI, dont worry, sooner or later global warming will take care of all that treacherous rain!! :D

For sure. We'll be looking like Venus in acouple years.

 

yea that happened to one of my buddies in his old prelude. he went through a puddel of water forgetting about his CAI and yea car just died and come to find out a rod blew threw the block, it was nuts.

 

Can someone explain the physics of how a little bit of water can cause rods to do ungodly things like shoot through a block? I see how it can mess up a motor, but destroy the bottom end? Explain por favor.

Water is not combustable. When the piston is at the top of its compression stroke the water will not ignite and will cause the rod/rods to bend. The water has no place to escape so in turn bends/breaks the weakest part of the internals.

 

its major suck.

ICEBOX FTW!!!!!!!

 

i hydro lock my Accord, Had an AEM CAI. Didn't even drive through a puddle. It was raining fairly hard, i was on my way to school and my motor shuts off. Pop the hood and see a nice rod sticking out of the block.
When i replaced the motor I chopped that intake in half.

Thanks

I guess i will be shortening my new intake before it goes on

 

JUS BUY YOUR SELF A BYPASS VALVE....

it defeats the purpose of running a CAI.

(the purpose being a few extra hp that will be lost by the bypass)

not only that. Water does not compress. The piston and rod hits it, and they cant travel the full way that theyre supposed to. They have no where else to go vertically, so they have to go somewhat horizontally, so they bend.

Also, the CAI doesnt have to be submerged like a lot of people say... I have a CAI and I drove through some water that the bottom of my car/bumper wasnt touching. I had my splash shields on the bottom of my car on and a truck drove past me, my engine shut down.. It was hydrolocked.

I'm guessing the truck splashed some water up through the wheel well or something. I was driving maybe 5 -10 mph when this happened, so my tire wasnt throwing enough water up there. It's a lot easier to hydrolock then most people think.

Water does not compress well
It doesn't make it to the top of the stroke and the crank slams into a stuck rod.

I suggest everyone to stop being such pussies... I live in NJ where it loves to rain and never had a problem with my GSR.. and if your so scared of hydrolock get a SRI and lose power cuz all they do is suck hot air... actually i could have just said they suck... or if ur extremely afraid of getting water on your filter get this:



And no it doesnt deprive HP...

 

Only one person mentioned the splash shield.

How many of you morons are driving around with a cut, missing, or modified fender liner or the little peice in the bumper that pops out so that nothing but the coldest of air gets to your filter.

That's the biggest reason for hydrolocking. I've driven in bad weather with my cold air with a full fender liner, etc and never had a single problem. Mind you I don't go submerging my car in pot holes.

CIA is fine. just don't modify your splash shield.
