well.. i took out my injen cold air extension last night off of my S14.. &nbsp; after the last incident of hydro locking during the last raining season.. <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/withstupid.gif" border="0" valign="absmiddle" alt=':withstupid:'> &nbsp;i decided to take a little precaution and go back to short ram mode.. &nbsp;BIG MISTAKE!

well &nbsp;needless to say im pretty angry at the car now. &nbsp;it feels.. &nbsp;extremely slow.. &nbsp; <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/cry.gif" border="0" valign="absmiddle" alt=':cry:'> &nbsp;and ill tell you how i notice the difference..

engine revs slower.. &nbsp;most notible around 3.2k rpm.. &nbsp;it just takes a while longer now to rev up to about 4.3k.. &nbsp;

the loss of pull i used to have after 3.7k..

on the freeway i could instantly go from 70 mph to 80 mph in 5th gear.. &nbsp;now it takes so long..

overall it just feels not so sexy..

i believe the total power may be the same.. but the power band is a lot narrower.. &nbsp;and higher up in the rpm band..

with the extension my car will start kicking at around 3.3k rpm.. &nbsp;now it just feels like a little push.. &nbsp;

needless to say.. i think i might just put the extension back on.. &nbsp;if i blow the motor.. &nbsp;oh well im swapping it anyway.. &nbsp;

If you hydo-locked your motor you would not be driving the car with that motor iirc.It completely fu**s your motor up and destroys it.I have benn driving with the cae for about 6-7 months and well there is no water comming into my intake.Unless you submerge you car into water nad gu it you will not get hydo lock.

I've only had my CAE for a month now and I don't think you have to be too worried about hydrolock. It been raining alot here at Radford for the past few weeks and I haven't had any problems yet.

It might not be the case... From what i'm thinking it would only be a mjor fuck up if the water made it all the way through into the engine.... and that would be quite hard to do. The car would just turn off or something from what i understand... right?

Btw, i have an aem bypass thingy lying around on a shelf. It's used a bit and missing one rubber piece, but it's no bigy. I'd sell it to you for $20 shipped if you want... except you gotta check what you have to do to make it fit injen intake. I saw some cars that made aem bypass work with injen, but check to make sure...

from what i was told to insert the bypass on an injen you just make a simple cut on the straightest part of the short ram... BTW im not all that sure if the source was reliable hes a honda boy thats had truly hydro-locked his motor... good luck

to hydrolock your motor you have to submerge the whole filter and thats alot of damn water. the bypass will work but it needs to be near the same height as the throttle body so dont put it all the way down by the filter. i ve had a friend hydrolcok their engine once and it coompletely focks it up, remember, water isnt compressable like air

well whatever i did.. hah my car died in the rain.. <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/dozingoff.gif" border="0" valign="absmiddle" alt=':zzz:'>

we'll just call it an almost death..

and normal people shouldnt worry.. &nbsp;i just dont have any fender lining.. &nbsp;whoops.. &nbsp;so that would cause quite a bit of water to go in..

How does a by-pass valve actually work? Does it just catch any water coming it or does it have a sensor on it that detects water and stop letting in air (but wouldn't that mess an engine up)?

It's a spring loaded valve set to open when vacuum is present in the intake track. &nbsp;When the filter becomes submerged in water, the intake track becomes a huge straw with the engine sucking on it creating sub-atmospheric pressure. &nbsp;This vacuum "sucks" the valve open both relieving the vacuum so water can't be sucked up the intake and providing an alternate route for air to get to the throttle body (although, this route is unfiltered). &nbsp;It's a good idea and should perform it's job, but it's unecessary IMO as long as you stay out of puddles deep enough to seep into your door.

Kreator, if it's missing a flap, it's no longer a valve...it's a (unfiltered) hole in your intake track.

There are no springs. If there were it'd prolly be around $100.

The part my valve is missing is the connector on one of the sides. eg it's 2.5" on one side and 3" (cuz it's missing the insert) on the other. If you put a hose around it, it'll work just fine (important part is that no air gets sucked in through it). So it has no interference with how the valve itself works.

Can someone explain what happens when the car hydrolocks? What i'm thinking is that when u hydrolock, you mafs doesn't get any air through it, so there is no gas going in so the car shuts off.... is htere a flaw in my statement?

When I say spring-loaded, I don't mean a conventional coil spring. &nbsp;There are many different kinds of springs. &nbsp;I mean that when the flap is pulled back, it returns to its position under on it's on when the vacuum is relieved.
And hyrdolock is when water is sucked into the combustion chamber. &nbsp;As the piston begins the compression stroke on the water-filled chamber, it is stopped because water doesn't compress like air does. &nbsp;So the force that was pushing that piston up (from one of the other pistons being pushed down during the combustion stroke) has to go somewhere. &nbsp;I'm not exactly sure what actual damage constitutes the term hyro-lock, but it could probably include anything from a broken crank to broken rods to a screwed head.

Ok, but in order for that to happen, the water gotta make it all the way up the intake into the intake manifold. Won't the car shut off cuz no air is moving through? (it'll become less dense since water has that viscosity thing and won't move up fast enough...). That's a long ass way to go. If you just hit a water puddle or something, eg u don't get stuck there for more than like half a sec it won't make it all the way up there before new air comes into the filter and makes it's way through the water.

Oh and the result of water getting in is prolly gonna be a bent rod, if you drop the little stuff (like spark plugs, injectors etc)
