~~~~POWER, POWER and MORE POWER

Hi all, special thanks to all who helped me pick out this CAI, the install tookslightly longer the normal because i am not as handy at relocating the coolant res. as i thought. other then that i am proud to say that i am successfully running on the CAI and coupled with the Borla exhaust, the power increase seems to be double. most notably in the 3500 and up range. Kicking the car into over drive off and gunning it will really let you feel or see the boost in acceleration. Also she does feel slightly ligher on her feet.


~~~~Hydrolock Myth

In regards to the Hydrolock issue and concern I must say, I was very worried about it because i guess i didnt understand. So i made a few calls, one to Injen and then on to K&N the injen response was not really informative beyond whats on their website. But when i was talking to the guy at K&N about it he took 20 minutes to give me senario run downs and why they say unless the intake is directly exposed to water or submerged at the filter level the odds of a hydrolock is as likly as a random spark plug failure, He did stress the whole point of how K&N take their approach to filtering dirt and other contaminates, and the fact that the filters they make are saturated with their speical lub. even when exposed to small ammounts of water, the water should not pass thru the filter, instead it should just be absorbed by the material within reason.


~~~~Fact

Now your greatest chance of getting a failure due to hydrolock is if you say enter a car was that gives the under bely of the car a jet wash. In that case if there is direct exposure to water then its possible for the filter to be over saturated and leak water into the engine but only at higher throttle ranges. the energy need to pull the water thru the filter and up pipe is great. so as some say, WOT will do it for sure. but still at that time there is only a theoretical risk.

now crossing a river or flood thats adiffernt story. anyone in there right mind wouldnt do it.


Well, thats what the tech said.

Anyone agree? disagree, i t made sense to me

 

My 2nd gen had an AEM cold air intake system installed. I just happened to be driving through a storm when I encountered a dip in the road I couldn't see. Hydrolock, does exist and it can happen to ANYONE that has ANY cai.

The fix?

A by pass valve...which after several people suggested I purchase one, I did. I didn't install it though, I was being lazy. And, well I paid the price. The cai tubing sucked that water right up through my intake mani and you guessed it. The engine seized and shut off. I tried to restart it and that's when I knew. If I knew what I know today, I wouldn't have tried to restart the car. I would have just pushed it to the curb and waited to have it towed and then drain the engine. But, due to ignorance, I tried to crank her up and I bent every rod in there.

Bottom line:
BUY a BPV if you are going cai....AEM sells them.

-Phil

Tid bit...I STILL have that BPV as a reminder....yah...and that was like in 2002.

 

I have heard that the BPV hurts performance alot.

 

If you put a bypass thing on your CAI, it WILL negate any positive effect the system causes. Omron, congrats on getthing this installed and good job doing your research, but this is all pretty comon knowledge. I dont think anyone thinks that you can get hydrolocked by driving through a rainstorm. The only way it will happne is if the filter itslef is partially submerged in water, then you're screwed. If you ever see a big puddle coming up on you, either avoid it or kill our engine before the water reaches the filter, even if you have to walk through the water to get out of the car. Wet shoes are better and easier to fix than having to tear down and dry out an engine.

 

What else would you expect the manufacturer to say? Hydrolock is real, given the right circumstances, and a number of people on the Forums have reported on it and experienced it.

 

He said he talked to a K&N rep, not an intake company rep (, well, the typhoon, but there has to be a reason that it was built to be converted to an SRI quickly. Oh well.

 

I hear you on that JDM, River puddles are a scary thing. But one thing the guy said to do, which, like the geek that i am. Do an experiment, create a mock CAI tubing, with cloth, lol find the biggest puddle or riveryou can, and run your car full tilt thru there, back and foras much as you can, if you pup the hood and drag the towel outta there it should be bone dry, Because of the well design of the protege no water should be hitting it directly. you should be able to set it on fire no problem lol

Anyways, when we did the towel test we drove up and down and i must agree the only reason why i agreed to go along with it is because it was my friends protege so i didnt mind WOT it with no fear lol.muahaha

but anyways, when it comes to even moderate rain on the ground, the bullet forward design of the protege wells and even uner the rad keeps everything bone dry, which i can comfirm because a while bck i had a Radiator lead problem that was leaking left and right and those stains are still there and never got touched by all the rain. even after driving in the snow, there was never any water in those area just the dried coolant.

But as JDM said, river driving can do it to ya. But from what most people tell me its gotta be alot of water your car has to be litterally pushing water.

well in toronto there isnt muchrain so iam not worried. and its good that the intake is on the self side and not the right to avoid gutter water

 

Your starter wouldn't have enough torque to bend every rod in there.
If it happened at all it would be from the running engine, NOT from trying to start it. And if a cylinder was completely filled with water on the compression stroke assuming it was, then your starter wouldn't even crank the engine a half degree.

Personal experience: 88 GMC safari van, 4.3l engine.
THis bitch had a blown headgasket, or possibly a cracked head. Frequently, when we shut it off, the pressure from the cooling system would expell water into the offending cylinder and if it happened to have been shut off on the compresion stroke then the starter would crank for half a second and then stop depending on how much coolant had leaked into the cylinder. Well, that was that, unless you held the key and the torque from the starter motor would force the water out of the cylinder through the crack/shitty headgasket and the engine would fire up. Even that starter didn't have enough torque to bend a rod.


Question though, since when does anybody besides ES make a CAI for the second gen?? Or did you buy one and mod it to fit?

 

Question would failure happen at low RPM (Hydrolock)

Everytime i hear about the storys from Hydrolock its because of high RPM action. what about low end power.

what would happen if water begins to enter, would she stall or skip a heart beat?

anyone

 

Well the reason you hear about it happening more at higher rpms is because there is more air going through the pipe, so the same applies to anything else around the filter, such as water. At very low rpms (less than 2000) I doubt that it would have the pressure neccesary to suck water all the way up that tube.

If by "begins to enter" you mean a very small amount (less than a teaspoon) at WOT, it would probably give you a little bit more power for a second (water injection is sometimes used to cool the charge temps, giving more power). Now if you mean a very small amount like a couple tablespoons, you will probably dramatically lose power and flood the engine with gas because as it's entering the cylinder it would mix with the water and the entire mixture would not burn, and eventually it would fill to the point where it would suddenly and viloently come ot an abrupt stop.





This is all me talking out my ***. I dont know this for sure because I've never had any experience with it. But theoretically, this is what should happen.

 

I've driven through some heavy *** downpours and my car is still running.. maybe because I have a homemade spash guard under my CAI.. basically I read about the hydrolock and got scared pantsless. I put a huge guard around the filter. I have a small duct going over to the filter from in front of the engine.. kinda like the stock setup. That is what kind gives me the cheapo forced air. WHEN there is a rainstorm and I have to drive, I just open the hood and close off the "forced air" intake part with a section of metal that just blocks off the intake part of the thinger. Know what I mean? Kinda like.. a rubber for it. So i dont end up getting screwed over by a stupid mistake.

 

Yah....what he said /\ /\
ha ha.

 

Phil, I think he was actually asking you a question there dude. And asking you to explain how your rods really got bent, cause I agree, a starter motor doesn't have the power to do it.
