turbo spool sound turns into a squeal at 3k

[kjohn09e]

Over the past 2 to 3k miles. when I'm in 4th gear or higher, at WOT once the RPM reaches 3k, the turbo whistle changes, higher in pitch, more squeal like as if there is a major boost leak somewhere. im starting to think the stock BOV may be giving under the pressure? im at almost 34k on the car now. any thoughts?

[MENTION=759]Hijinx[/MENTION] hard to get it recorded well on my own but you can hear it once I shift into 4th. I'll try to get a better video here soon.

Sounds like...oh, I don't know what it sounds like because there's no audio.

As always did you check ALL the hose clamps?

 

[kjohn09e]

when I opened up the bottom portion of the grill, since i had the bumper pulled. i tightened every hose clamp hoping that would solve the issue. i have the boomba bov adapter but that doesnt sound like the problem.

I'd take the boomba off and see what happens

 

[SirSlaughter]

Dude, I have this EXACT same noise coming from my car! Finally! Someone else has this issue!

In all honesty, check your Boomba Adapter. I also have the boomba BOV and after a hard pull or two it gets that exact high pitch noise. It almost sounds metallic to a degree?
I only have 15K miles on the clock. It started happening after I took it to the track a few months ago and let it get some bad wheel hop. So I think something is either loose, or the boomba BOV might be the culprit.

Do what 15FiST said and take it off to see the difference. I would do it, but so far performance has had no impact and the car runs perfectly aside from that noise after a hard run.

Let us know if you find a difference.

 

[Hijinx]

Yeah, def gonna need some better video. Because it actually just sounds like BOV noise.

I get that exact same sound...I also have the boomba adapter...however I didn't start noticing it till I got my car tuned and it only seems to happen when the outside temps are very hot...like 90 plus

It seemed normal to me...couldn't really tell from the video audio.

 

[kjohn09e]

I do notice it more when its hot outside. It started on a pretty aggressive drive through some windy roads. Really worried me at first. It is almost intermittent at times as I almost had trouble replicating it for the video. Only thing running through my mind when I hear it now is "well there goes my boost pressure"

that is the problem. i had it happening to me, took off the boomba and its gone.i also have the 2j race intake so it sounded like it was inside my car. like a bird was chirping. or a rally car chirp.
