Is the bypass worth the trouble?

I just recieved my AEM Bypass Valve in the mail. But after reading the directions, I don't know if i want to do the installation of it.

I have to cut the pipe to add it in. Can you engine guru's help me out?

Should I install it? Does it really work? HELP PLEASE.

Also, I live in Charleston, SC. For those of you who don't know the area, it is below sea level so we get a stable amount of flooding year round. Should I go through the head ache to save my engine?

What is gonna happen to the engine if water gets sucked up into it?

Hey,

Sport Compact Car did a test of a bypass valve a while back (here (http://sportcompactcarweb.com/tech/0104scc_tested/))

Here is what they said would happen to the engine...


OK, so what's the big deal? Think about what happens next. Say you have a 2.0-liter engine, so each cylinder displaces 500cc. If just one of those cylinders sucked in just 100cc of water (100cc is only 5 percent of what's in a 2-liter bottle, if you are having problems thinking metrically) the end would be very, very near.If this engine has 10.0:1 compression, for example, the combustion chamber would be reduced to just 55.5cc when the piston is at top dead center. As the piston goes up the compression stroke with 100cc of water in the cylinder, impending doom is near. Air will happily compress as the piston moves up, but water will not. As soon as the combustion chamber is reduced to 100cc, the piston will stop. No matter what. And then the engine will stop... if you are lucky.

I say use the valve, save your engine :)

it would be kinda hard to argue with a car maganize, but maybe theyre saying it to help profits(just like the government enforced bike helmet law... wonder who's gettin rich off that). anyways, everyone ive ever talked to said its useless. the only way your intake will actually suck up water is if the filter is submerged. so you pretty much have to be driving through a lake or a 2ft deep puddle. and then it also hurts airflow and therefore performance.

but if you still wanted to put it in, why would you have to cut your intake?? the one you showed before in your sig was a two piece cai.

What would you rather do?
Cut your $200 intake,
or buy a new engine.
Seems like a pretty easy answer to me.

Also I remember reading that article in Sport Compact Car. They installed it on an NSX and showed a picture of the water making it halfway up the pipe and then stopping, so it does really work. If you think about it its pretty simple how it works although I don't know how to put it into words.

The intake pipes are 2 different sizes. It goes from a smaller pipe leaving the throttle body to a bigger one heading to the filter.

I would have to cut the put leading out of the engine.

Thanks for all the help ya'll. I guess i need to get out the hack saw.

oops, my bad. didnt read carefully enough. in that case id like to change my mind. you definetly should!

Fly Rice Racer: where'd you get your intake from? maybe they just dont make one for my model, but i dont recall ever seeing a 2piece aem before. is that just so you can switch to a shortram if you want??

Fly Rice Racer
10-22-2002, 07:07 AM
Every AEM CAI that I have ever seen comes in 2 parts.

I got it from modacar.com

The short ram is a different shaped pipe.

I know freed0mfist had to cut his intake out to put in the same cai as yours, he fucked up his finger, but said it wasnt too difficult.

shit i think its worth it i wouldnt want to risk my engine hydrolocking

Fly Rice Racer
10-25-2002, 07:07 AM
If you hydrolock the engine does that mean it's dead forever? Or that it just has to be rebuilt? I only know that it's bad to get water in the engine, but i'm not sure why.

10-27-2002, 08:29 AM
lol someone made up hydrolocking ur engine cause I sure as hell know it is impossible to lock an engine from water unless u drive throuhg a damn river or something. Yes u can stall out maybe get water running in ur intake ports and cylinders and maybe damage some sensors get some water in ur oil but hydro locking? It is expensive to have the water cleaned out, is that wat ur refering to though, getting water in ur engine? cause the only was I could see ur engine lockin would be if u got water in ur oil and it thinned it out so the piston seized in the cylinder but that would take time.. I have also asked about this and my boss looked at my funny... but yes I think aem's bypass valve is a good idea, only cause I got water in my engine before, lol.

hydrolock is very real. move your arm up and down in the air, feels ok right? now go punch a brick wall full force....doesnt feel to good huh?

i dont usually stick up for bullshit car mag's alot but water cannot be compressed by an automotive piston engine. and when you have that much pressure on the compression stroke stopping the piston from making it past TDC all that pressure needs to be relieved somewhere so its energy is transfered to everything around it untill it reaches a weaker part and thats what breaks aka spun rod bearing or cracked cylinder wall or a nice big hole through the top of ther piston or a nice egg'd rod. hydrolock is basically like very very very bad detonation only water is what stops the pistons upwards movement not a pre ignited mixture.

TheBum

hydro lock seems like a very real thing to me too.
It would take a good amount of water to do this though, because I would assume that water sucked up through the intake would be somewhat distributed throughout all 4 cylinders, allowing the engine to still move. But still, any water is no good at all.

Are you talking about SCC? I heard someone else say something about them being wrong or something too... Out of all the magazines in the bookstores here (Import tuner, Superstreet, SCC, and Turbo), I only read SCC and Turbo because it seems like they know their stuff...

Import Tuner and Superstreet are garbage, but I will buy them if they have any big Nissan coverage/ Nissan cover car :)

What have you done to your car that is so great. I've only had my car for 3 months and look at those mods. I have more on the way.

And you have such great comebacks. I'm impressed.

Wow, they were so good, you had to use them twice. What's the matter couldn't come up with any better ones?

If you really wanna race and talk hardcore, I'll borrow my Trans Am that I sold to a friend and bring it. Then we both have 2 cars to race with.

I'm a college student with bills, car payments, and a girlfriend. So I can't put as much into my car as i want to. Its a build up project.

An asshole like you as you claim to be probably doesn't have a girl or any schooling.

I'm a nice guy, ask anyone here. I dont' exxagerate my stories or dish out shit to people who don't deserve it.

I still love how you are making fun of my altezza's when you have them too. And if you are such a car enthusiast you probably have an intake.

I have nothing but love for ya.

Good luck in any endeavors.

That's great for you man. I'm happy for ya. Problem with the 7th gen civics is that they aren't making any turbo or super kits for ours.

So I am gonna have to get a custom made Supercharger which is gonna suck an assload of money. Or i guess i could do a K20a swap which is gonna cost even more.

I wasn't doubting your ability with cars. You still don't have to be an ass about it. This is why people hate honda owners. Because the ones who have done all this work on their own are no help and they act like a jerk to anyone else. We are all in it for the same reasons. Just because yours is done and others are still working is no reason to be a jerk.

Like I said, I'm not pissed. I've got nothing but praise for ya.

It's just gonna take me a long time to get all of that done to mine.

OK Here we go....

Let's call it even and stop this petty bullshit.........Lets not waste anymore time or energy on this.....I know I'm an asshole as I already said....I can keep going but fuck it....Lets not

Sounds like you have a plan....

The Problem with the New Civic Si motor or Type S motor is you need Honda to put a code in to have it run in you car once installed.....It's a new thing for the 2003 Civics but it also might be on yours I'm not sure....


They need papers showing how you got the motor and so on....Which to some is not as easy as it sounds....They also won't activate a J spec motor.....In the Us so I'm told..

Remember I am a Honda/Acura Encyclopedia...So if you need help..

If I don't know it it's not hard for me to find out......

11-03-2002, 08:07 PM
Ok man. We are all cool now.

Yea, there have only been about 5 of the K20a swaps done so far. They run about $10,000 to get done at the moment and you are put on a waiting list.

But it will probably be a while before I get that done. I just want a car that I can have fun with right now. I'm not looking to toast vettes or anything. I just wanna be able to put the hurt on any other honda and acuras in town. Most of the kids here are rice luvers, so it shouldn't take much to beat.

I also wanna be able to beat my friend's V6 Mustang. Which is not gonna take much longer to do. I am really close right now.

I'll be sure to ask you if I have any questions.

First of all, I have a 2002 Civic........not a 2001.

Do you see one damn sticker on my car? Or even LED washers or neons or any of that shit? NO

I came here to ask a question to the technical guru's here about my intake that I got. That question was answered with no problem. And you didn't have one bit of helpful advice so I know you can't be referring to yourself as a person who knows what they are talking about.

It's ok though, I don't expect you to understand anything that is discussed in this forum. I forgive your newbie arrogance.
