Takeda Short Ram Intake installed, making a weird noise
 

Hello friends :) I just installed Takeda intake and it is making really annoying sound! As you can see in the video, it makes that weird whistle noise the whole time, even when I'm driving, and turn off the engine. It is very annoying!! I make sure checked everything if things are loosen or if MAF sensors are loosen but everything is perfect! (btw, installation was such a pain in the ***. I don't know if it's only me but omg nothing fits!!! everything I had to force to put together, silicone piece that connects the throttle body spacers and the intake was so short that I had to force it so hard, then when I tried to tightened up the hose clamps, silicone would fail to hold together because takeda put so much grease!! Tightening up the filter also was pain in the ***, it has no some kind of restriction to stop filter at the certain point, it was just like you tight up the filter where ever you want to..-_- plus too much grease again... The MAF sensor port was located on the bottom of the intake so I had a hard time plunging the wire in...so stupid...THE WORST intake ever you can ever get! Very cheap quality! My intake didn't even come with those red decals on the pipe as you can see in most of Google images of Takeda intakes...) I never got CEL so far...So what's the problem??!! Thanks :tiphat:

Holy crap that's annoying, does it get louder when you give it gas? Are you SURE it's the intakes???

100% SURE!! it is from the intake! NEVER had this problem before when I had stocks on. Possible vacuum leak? But no leak! I checked everything! T^T

It stays same like that either I gas it or not T^T so annoying

It looks like you turn off the car and the sound emanates for 3 seconds or so... Shoot me a text (310)eight nine three-4207, lets get this resolved

Jeezus that's a weird sound... i have a feeling you bumped or messed something else up... I really forgot from my install but does the 370 have the baffle system on the intake?

Ok thanks! I will shoot the text after detail observation tomorrow because I'm going to go to sleep now haha! Thanks anyway! I'm going to keep look for the solution tomorrow

Hey my friend just texted me that it is normal sound. He told me that it is throttle opening sound and it's normal. hmmmmmmmmmmmmmmmmmmmm

that's not a normal sound

I know...this can't be a normal sound.........arggg!! :mad:

Sounds like a vacuum leak somewhere. I know you said you checked everything, but I'd double check again one more time just to make sure all the clamps are on and where they're supposed to be. Also check the lines that weren't included in the install, but might have gotten bumped loose from the installation, as complicated as you make it sound, something might have been nudged loose just from fighting the intake. But that is not normal. However when revving, it sounds good. :tup:

Thanks for the write up. Yes, I always thought it would be the vacuum leak...
Here is the Part 2 video

At the end, my intake whistles and sing "I believe I can fly" just jk lol. damn this is annoying...I'll double check

SEND IT BACK, SEND IT BACK!

Starting a chant...

I wish...but all the effort of installation and shipping fees...I will try to fix the problem and if I can't, then send it back! :)

Man that is weird... But it sounds like it's coming from the front of the bay, and not the back, which would remove vacuum lines... Maybe check in see if something is rubbing on a belt or something?

Another idea would be (and you're gonna hate this) but completely go back to stock now, and then see if the noise is still there... If it is, you have a problem somewhere with your engine, if it isn't you know it is the intakes...

Then if it isn't there, reinstall everything and see if it comes back. Yes, this is completely labor intensive, but it's the other troubleshooting process I can think of...

When I had my stock intakes on, I had NO PROBLEM at all. It is def Takeda intake. I'm going to drive one more time today, trying to gun the car and see what happens. (haven't had chance to gun it after the installation) If I have to do what you have suggested...awwww I'm going to kill myself lololol:roflpuke2:

Did you happen to do the soft ECU reset first? (Not that it will help with the sound so much as it's just a good idea to do when you change breathing mods)

I didn't reset the ECU. but I think resetting ECU won't solve the problem. :(

It's not about solving the problem, it's about getting your ECU to learn the new airflows thanks to the new intakes. So its a simple way of letting your car adapt = more powah.

aight bro. I will reset it :tiphat:

Trying to contact Takeda for the solution.

this is a HUGE stretch on my behalf. I think that it is your fuel pump *the whine that I heard.* what year is your z? Some of them did have a recall with the ecu or fuel pump in reguards to that whine/whistle sound. Could also be a vacuum leak?

My Z is 2009. really? I never knew that we had a recall???:confused: oh I hope it's not ecu or fuel pump problem.. T^T

so this is what Takeda sent me back regard to the noise problem (I also attached the video to Takeda) "I would like for you to adjust the air filters. I have reason to believe that they may be too far on the intake tube. Just pull them towards the end of the tube. They don’t have to be moved very much. Another thing I would like for you to check is the CCV or Crank Case Vent lines that attach to the intake tubes. Check to make sure that they are not kinked or bent. The last thing that I can think of to check is the MAF sensors. I would loosen them and wiggle them, then retighten them." I'm going to do this right now see what's going to happen

So I tried everything today, took out the whole intake out to see if anything is wrong in the pipe or MAF sensor, nothing was wrong. After carefully listening for where sound could be coming from, I noticed it is not from the intake! It is somewhere in the engine...now I'm doomed...nothing sounded like this when I had stock intakes on, now it is making this weird *** sound after Takeda....sigh...

Take to dealership and pay the$50 for extended warranty check. I think its your ecu. There was a thread about this somewhere on this site about it. I'm bettin my dollar on that one.

Do I possibly have to change my ECU? One of other members sent me a pm saying he had the same problem and after changing his ECU the sound didn't go away. I guess I'm fine but the sound is annoying for sure:roflpuke2:

They will most likely change the ecu if thats the case. I'd take it to nissan and see what they say. Has your car been re flashed or uprevd?

nope. I have a stock ecu :tup:

yeah I'd have nissan take a look at it. Atleast they would be able to pin point what it is that is going on.

that's one crazy sound. it persisting after shutdown kind of says to me that it's vacuum / PCV breather tube related. i would check to make sure that the clamps for the breather tubes are completely tight and that there's no looseness not only at the intake but all the way down.

I checked everything and bought extra hose clamps to tightened up every single tubes that could possibly leak, but still no luck! :inoutroflpuke:

btw is there anyway I can get heat shield for this intake? What if I call K&N or Stillen if I can only buy heat shields? You think they would do that??

did you ever figured out what was causing this?

resurrecting this since it's easter n all. ever figure it out? I think it's a vacuum leak. I have the same issue after installing K&N and post maf tubes.

Exact Same issue
 

So yesterday i installed the Takeda SRI. Well i have the exact same issue. Its a (dog whistle) type sound coming from the drivers side intake. Ive tried al the steps that the factory suggested in the post and noticed what i think could be the issue.

When i took the filter off and covered the intake quick in sucked my hand and noise gone. So i loosened the bands holding the pipe on and removed it (left the small ccv, Crank Case Vent connected and still had the noise. Then i relieved it had to be that ccv so i looked at stock part vs new pipe and the ccv inlet is smaller then 1/4" while stock is closer to 1/2". Im guessing the smaller hole creates more suction speed but i believe its also making the whistle. I am planning to bore it out a bit tomorrow, any other suggestions?

Also, after the install i noticed right away my service engine light is illuminated. i had the battery disconnected so figured the ECU would get used to the new intake, hoping thats the issue. I will be checking codes tomorrow as well.
Last the the idle is now high it seems (about 1100 warmed up).

Hope i can straighten this out because it looks and sounds mean (besides the ear piercing whistle!)

Please help

bump!

What was code?

And you said pulled off filter to trace down sound , so u may need to check all connections again and do reset to eliminate check engine light.

Hate to bump this guys but I have the exact same sound. Appeared after my first track day. Any suggestions?
Cheers.
