Injen CAI Hydro-Locking questions.

[tat2ddeviant]

Looking @ buying an Injen CAI for my 02's MP5.

Anyone had any issues w/ Hydro locking w/ this CAI...? I know you can't be an idiot and go driving through knee deep puddles. I'm just curious about how concerned I should be w/ the possibility of hydro-lock occurring. I specifically wanted an Injen b/c of the Air Filters placement inside the driver side front wheel well. It seemed like a fairly sheltered location to place it. I know AEM has a by pass valve, but I'm not certain where I could install it, w/out cutting the intake Piping....

Any info is appreciated...

unless, like you said, you drive into a puddle(lake) that would fully submerge the filter then you'll be fine.

Also, you should know what roads in your area flood w/ rain and which ones dont. You just have to remember to be smart and not drive down those roads when there has been flood causing rain...

I don't have an Injen but did a CAI with my Hiboost intake. I am slammed and my filter is at least 10" from the ground.

I've been running mine for over 3 years with no problems. Don't worry about it. You'd have to drive in some pretty deep water to cause hydro-lock, and the filter would have to be almost completely submerged in order to start sucking in water.

Like you said yourself, don't "be an idiot and go driving through knee deep puddles."

You'll be fine, trust me, in my last car I had my filter dripping with water (don't ask) and it still didnt hydro-lock. It takes alot of water and alot of pressure to get water that far up the tubing.

I've actually come close but basically the engine died before it let any water into the engine. So as long as you drive through the puddle with the engine idling, you won't suck in any water. If you rev the engine, that may be another story though. It's nothing to really worry about unless you come across a road that's covered in water.

I had an AEM V2 intake on my Civic up until two weeks ago when it sucked up enough water, at idle mind you, to put a rod thru the block. I crested a hill, saw a big puddle. Couldn't stop all the way, but got slowed down to next to nothign with the clutch pushed in. Sluurrrp, bang. Attached is a pic of a piece of the block I salvaged from the ground.

Not entirely on topic, but keep in mind that the tube for the V2 is about 5" in diameter until 3/4 the way to the throttle body, where it shrinks to about 1 7/8" or so.

Not being a wise-ass; serious question. How does hydrolocking an engine put a rod through the block?

To give you a brief answer, Water isn't compressible.... like air and fuel vapors are....

Water essentially decreases the size of your combustion chamber....when your pistons expect to have a 500CC displacement, and suddenly run in to water, which reduces the available combustion space, the pistons stop short.. and bad things happen..

Exactly. You catch that piston in the power stroke with all 4 valves closed...kablamo. If I'm lucky, it didn't smack any valves, or ruin anything else more than it did. I'm hoping to salvage as many parts as I can.

But, I like the looks and sound of the Injen inake. I'd seriously put one on my P5...but, after my last experience with a CAI, I'm hesitant unless I get a bypass valve for it. I guess it depends on your climate. I'm living in the 2nd cloudiest area in the continental US (after Seattle of course), so it tends to rain a bit.

the only thing I dislike about the CAI on the proteges is that you have to open the wheel well every time you want to remove/clean the filter

Makes absolute sense. Thanks.

A member here (GNO) hydrolocked his motor with the Injen CAI. I even went over to his house and saw the hole in the block!

Just be careful or move to Arizona

yea i had and aem on my p5 and its like barely off the ground since my car is slammed, and i drive through hard rain all the time with no problems. but thats all just luck, some people never have problems, some go out in a drizzle and motor goes boom

 

[Ki||ian]

I have the Injen CAI on my P5 with no problems. Hell, I even cut away the plastic on the underside of the bumper so it is completly open to the fresh air.

I drive in hard rain with my Simota CAI and have no problems if you gotta go though a puddle try to keep it on your passenger side. Like you said you don't to go jumping into ponds to see what you can get away with.

i live in cali, what the hell is this rain everyone is talking about!

It rained all the time in the "winter" when I lived in Tarzana area.

 

[DE31]

yea it rained twice this year LOL

two years ago though it did rain for a week non stop and i do remember once in my lifetime it rained for 2 weeks straight, but thats all changed now. i think its mostly night time rain (late night) and ends before i wake up so like a sneak attack

like when i'm parked outside thinking "its a nice day it wont rain" the rain gods on the other hand..... "looks like kelvin is parking outside tonight, now is the time to attack!" "hold on! lets wait until he falls asleep so he wont know what hits him! muahahaha!"
