CAI squealing - Club4G Forum : Mitsubishi Eclipse 4G Forums - 2006-2012 Eclipse Authority

tr1kst4nce · April 26th, 2011, 04:15 PM

My CAI squeals right around 2500 rpm... and I know it's normal for pretty much everybody with one on their 2.4 mivec. But is there any way to stop it or possibly figure out what part of the tube is causing it? Obviously it's in the top half (short ram half) that connects to the throttle body because it was doing it when I had it hooked up only as a short ram also.

Granted, it's not effecting performance... but damn if it isn't annoying. It makes me go REAL easy on the throttle or give it some get up to get past it just so I don't hear it cuz it sounds like one of those POS civics throwing a belt or something. It ALMOST makes me want to take the CAI entirely and put the stock intake back on.

There has to be a way around it I would think... any ideas?

tr1kst4nce · April 26th, 2011, 04:17 PM

The only thing I can think of is maybe it's the filter? Other than the actual upper tube (which I don't think it would be) it's the only thing that is in common when it did it as a SRI and a CAI. Maybe the angle of the filter?

Hell I dunno... I'm open to ideas/comments/etc.

is the oem tb gasket in the right position ? the nipple,so to speak,should be at the top and to the right towards the firewall.not every car that came out of the factory is installed right so i would check that if everything else is tight on the install

tr1kst4nce · April 26th, 2011, 04:56 PM

Hmmm.. not sure. I'll have to take a look. But if that were the case wouldn't it have been doing this before I installed the CAI? When the OEM intake was on?

probably not because of how restrictive the oem intake is

zedawg · April 26th, 2011, 06:11 PM

tighten all your couplers...this is probably a leak

tr1kst4nce · April 26th, 2011, 11:26 PM

Checked the couplers, and that's not it. If it was that simple I don't think so many people on here would have the same thing going on.

zedawg · April 27th, 2011, 05:07 AM

my CAI is making that but not at 2500 RPM...i have that sound in 1rst gear at 6000 RPM

Da Mister E · April 27th, 2011, 07:10 AM

my cai does not squeak at all; it roars after 4000 rpm, hope you get it figured out

snakeeyes · April 27th, 2011, 12:27 PM

as i stated,check that metal tb gasket.some poeple had squealing after they installed a gt tb because the oem gasket is not installed the right way on some cars from the factory.i have had several different intake designs on my car and i have never had the sqeeling.only a whistle from the gt tb.if in fact thats not it,then make sure your pipe connection to the tb is as close as it can get,maf sensor is good and sealed,air filter is on tight,and the ccv hose is not leaking.gl

tr1kst4nce · April 27th, 2011, 02:17 PM

I don't get why everybody else was saying they had the same issue and it was normal then. Check this thread I made about a month ago and look at the responses.

Listen... should CAI sound like this?

snakeeyes · April 27th, 2011, 02:26 PM

naw bro,i dont hear any sqeeling,your intake is just doing its job.forget about it

tr1kst4nce · April 27th, 2011, 02:33 PM

You honestly don't hear the little squeal that sounds like a belt wanting to go right at lower RPM's?... maybe I need to take a more clear/sensitive sound clip. Bear with me.

snakeeyes · April 27th, 2011, 02:43 PM

sounds good to me !! idk what to tell you lol.most people like this sound.

Yep, thats what I get-- no squeeling-- CHOP

Clovisman · April 27th, 2011, 03:26 PM

Check and make sure all your vacuum hoses are connected and that they don't have any cracks in the hose itself. and the check your CAI Tube and make sure you don't see a crack in the tubing wall. Any crack under extream pressure can make a nice whistling sound. And like someone said above, use a different brand filter can change the air dynamics/ how the air flows inside the intake.

I'll check all that again. I wonder if those filters they use on the Secret Weapon intakes are any good. In theory... they sound good.

No, no, no....

They might look fancy, they might work, but the WeaponR SRI is more of a problem for our members then a help, so I would say stick with a brand name filter like Injen, Fujita, AEM, or K&N.

zedawg · April 28th, 2011, 04:26 PM

weapon-R suck...thats it

haladafs · April 28th, 2011, 05:45 PM

i had no such problem with my fujita, was on for over 2 and half years. No whistle, no squeel noise, just hear air sucking in like a shhhhhhhhhhh sound lol

tr1kst4nce · April 28th, 2011, 06:48 PM

I've checked everything, made adjustments, still doing it. Listened to the CAI in my buddy's BMW and it has a similar noise (at different rpm's than mine) at lower throttle and rpm's, but just a slightly different tone. He said every car he's ever put a CAI on they all do something similar and compared it to whistling through your lips. Depending just how much air it's pulling it and different rpm's it will create a different tone in the whistle.

He recognized immediately the sound I was referring to and said it's completely normal. I guess I just don't like that particular tone. I prefer the whistle it gets at higher rpm's, not this one. But oh well.

He did mention that if I wanted to, I could put a few 1/2-3/4" holes in a couple different spots on my skid plate under the intake filter which would cause air to come in at different angles and could possibly even change the tone. And since I have one of those little hydroshield things over my filter I wouldn't have to worry about water.

We'll see what happens.

snakeeyes · April 28th, 2011, 06:53 PM

that hydro shield is causing your intake to suck harder and a member on here use to have your exact intake with the sheild and said the sheild dont do squat as he allmost hydrolocked.youd be better off to take the sheild off imo.

tr1kst4nce · April 29th, 2011, 06:56 PM

Strange... I tested the hydro shield and flung some water at it and it didn't penetrate but air gets thru it just fine. I'll take it off for awhile and see what happens.

I just figure a little extra protection while all these damn storms are rolling through can't hurt.

The hydro shield will prevent rain or splashed water from getting in; however, if your filter is standing in a puddle of water, i.e. submerged it will hydro-lock.

zedawg · May 4th, 2011, 05:29 AM

this is where the bypass valve gets in...if the filter gets completly into water the bypass valve will close the way to the filter and let air in by the valve sides
