Hey guys i have a 2014 WRX.
Mods- Invidia DP, Cobb SF, Turboxs BOV, Cobb Stage 2+
Im experiencing what i believe is a boost leak but I'm not sure. Im still hitting peak boost every time, but i hear this loud high pitch sound under hard acceleration. The best way to describe the sound is a tea pot on the stove. It doesn't make this noise every time, and usually only in 2-4th. It only last for a second or two. Ive already checked my DP, BOV, Throttle body hose and every other line i can and no luck. Ive been looking on the forums for a similar post/sound and can't find anything. Any help would be great, thanks!
I have the 50/50 BOV, i took it off and put the stock back on already and it still makes the noise. Im going to do a test this weekend and see if i find anything. Just wondered if anyone experienced this noise before. Thanks for the help/input guys.
I had the same noise. Hose to the IC was coming loose. Reattached with a better clamp, problem gone. I've heard others with the '11-14s who've had the same issue.
My ic to throttle body was coming loose and making the whistling noise. I put an aftermarket avo ic to tb hose and it went away but then came back a little bit. Im running srage 2 also and I think its to much pressure for the stock tmic. I went to a slwg map and lwg map on cobb to lessen the whistle and it helped
long story short....a new ic to tb hose will help but think higher capacity tmic is the long term answer
I thought for sure that was my problem but i took the hose off. Repositioned it and tightened it down good and still i hear the noise. That was my first idea to check but its on there good. ill try changing my map and see if that helps. Ill try and get a video up later of the noise.
I had to adjust mine a bunch of times. Hope you find it but im guessing thats where it is just like everyone else. The rubber got "warped" or folded funny on itself when i put it back on (if that makes any sense). I ended up ordering a new TB hose just waiting for warmer weather to complete the install.
My stock 2014 WRX makes a barely perceivable whistle........crap I thought this is normal.....my old 1985 Volvo 245Ti (with nice mods) and no boost leaks made the same noise.
I'll order a new hose and clamps and see if that solves my problem. Oilypablo you sound like you have a normal turbo whistle. Thanks for the input guys.
hey guys, i believe that i have a TB leak, but i am not sure. when ever i go past 3k rpm in 2-5 theres this farting noise coming from the front left of the car. like a high pressured fart sound. lol what do you guys think that the issue could be?
I'm not a fan of my local dealership so I just replaced it with the mishimoto hose because the stock hose is known for problems but I'm sure they would replace it for you unless they claim your modifications caused it
Its an easy fix. Ive done it to mine a few times now. take off BOV and remove the recirculation hose (make sure not to loose the gasket). Take off the bolt to the metal support bracket. take off the bolts to the turbo and it should slide right off. You may want to have some silicone lubricant to spray on the rubber parts to make it slide easier. Also may want a long set of screwdrivers and a flash light. When bolting the IC to the turbo be careful not to cross thread and to not over tighten. If you dont mix up the bolts you can tighten till the paint marks line up.
Today I am picking up my 14 sedan from the dealer for the 3rd time with a TB to IC hose leak. It would be hilarious if I wasn't so furious! This time supposedly they replaced the hose. If it happens again I'm tempted to get the silicone one and drop it off for them to install. )
Frightening that I took 5 minutes to read this forum and I now know more then they do. Yikes!
