Big increase in chance of hydrolock? (compared to stock)

What about removal of resonator?

aznt1217

Don't even worry about it. Search is your friend :P.

But I will be Nice. The Comptech Icebox is basically like your stock intake, DEFINITELY no need to worry about hydrolock. Intake resonator removal don't worry about it unless you intend in driving in 2 feet of rain. The only time you really gotta worry is if you are me (INJEN CAI), BUT I got a hydroshield so less chances of hydrolocking

Unless u take ur car swimming or like to cross rivers with it, you wont have any problems of hydrolock.

The chance of hydrolock with the Comptech airbox is slightly lower than that of a CAI. The intake horn sits pretty low, so be careful there.

Actually no, the Comptech Icebox has an intake pipe that replaces the whole stock intake resonator. It sits at about the same level as the Injen CAI's filter, just slightly higher.

icebox is still using bottom part of OEM intake which has a few holes to drain water, there is also a rubber bypass in it.

aaronng

When at throttle, with the intake horn filled with water, those holes will be sucking air in as well, so water already in the bottom half of the airbox won't be able to drain out.

Bypass? Didn't notice any bypass.

i'll take a few pics tomorrow. im too sleepy right now, time to sleep

Edited the thread title to be a question instead of a statement to avoid confusion.

ok, here are the pics :

2 holes + bypass :

fill it with water :



completely drained after 4-5 seconds :

Thanks for the pics. But yeah, it drains well without a partial vacuum in the box. Try connecting a weak vacuum cleaner to the end of the intake arm and see if the water still drains.

The holes are meant to allow air to be sucked IN, in the situation that the stock airbox/Comptech Icebox's intake horn gets filled with water. Anyway, the Icebox won't be hydrolocked if you go through deep water with light throttle because of the holes in your pic. But if a silly driver were to use heavy throttle to get through the water, even those holes won't save him.

Anyway, back to the topic, compared to stock, the icebox has a higher chance of hydrolock because the intake horn is in the bumper cavity. The intake horn of the stock airbox is just in front of the battery, at just 1" lower than the battery's top cover.

actually ive tried to do so, it still drained very well.

yea, they shouldnt driven the car through water at the first place, i dont think any modded cars owners are willing to drive through puddles.

Im thinking to cut the Icebox lower horn to decrease the risk of hydrolock, it will look like mugen airbox lower horn.
the problem is I already sold my icebox not long ago

stealth_dc5

so to hydrolock...the water level have to reach the tip of the horn?

no, hydrolock happened when water goes into the engine and make the engine stalled

I read somewhere in other cars forum, a large spray of water is enough to make the engine stalled. so a term of CAI filter has to be fully submerged is just a marketing ploy IMO.

hyun

i drove through a real bad thunder storm with flash flood warnings and an injen CAI, no hydro lock. i ran through alot of puddles too. car is still running fine



happy modding

For each cylinder, you only need 2.4L / 4 cyl / 10.5 (compression ratio). That comes up to be about 57 ml per cylinder to hydrolock.

I just wanted a simple answer for:

Is there a "greater" chance of hydrolock for comptech icebox compared to stock?

I've been thinking of getting the CompTech Icebox, but the install instructions for it say I gotta take off the bumper to do the install.

The way I look at it I should be able to just take off the driver's side wheel and get out the stock resonator box via the fender (according to the K&N Typhoon install instructions).

Anyone with a CompTech NOT take off their bumper? I'd rather go through the wheel well than the take off the entire bumper.

mjrchaos

Oh and the CompTech should have a lower chance of hydrolock over the Injen because the water would have to immerse the inlet air horn so as to create enough of a vacuum to suck up the water, whereas with the slighter lower Injen filter would reach that point a bit sooner. Plus the water would reach the Injen filter sooner that with the CompTech.

D'oh. I meant to post the CompTech photo, not the link.

Technically, the Icebox probably has a "higher" chance of hydrolock than the Injen. Why? If you look at where the air horn is on the Icebox. Water only need to reach the mouth of the air horn for water to go up. If you look at other CAI filter location, the filter may look lower, but the actual opening of the tube is higher at the top of the filter. Then again, since the Icebox is using a panel filter which may serve as a barrier to lessen the problem.

You would have to agree though that most of us would never drive in water up to the bottom of our doors, which is were the bottom of the CT Horn is.

mball

I had a friend in high school who hydrolocked his 89 civic by driving through a puddle. There were no modifications to the car. Would this be possible with the CT icebox?

moda_way

If the puddle is over 1.5' deep,

jlukja

You can absolutely install the CT Icebox without removing the bumper. I did it and there is a DIY thread somewhere around here that shows how to.

True, it would be crazy to drive through that deep in water even for a complete stock setup.

junktionfet

Considering the momentum of a moving car through several gallons of water, the construction details of the "cavity" where the inlet sits, and the proximity of the front-left tire, it may take far less than 1.5 feet of standing water to submerge the inlet just enough to ingest some water. It may not be enough to even penetrate the air filter, but don't just assume that the inlet will remain bone dry in the rain or while driving through a seemingly "safe" puddle--else you may find yourself replacing the short block.

Though some may think otherwise, the engineers at Honda are probably a lot more experienced and skilled than any of us. They placed the intake really high on the TSX/Accord for a reason. Does this mean you shouldn't modify your car? Of course not... But it does mean you should exercise a lot more caution than normal in the rain. While it is never a good idea to aim for puddles, those with compromised intakes should really watch out--just in case.
