My turbo is "whistling."

[Knox Joe]

Nope. 3in vibrant tb.

hmmmm..... weird, mine was gone as soon as I replaced the exhaust. Now I have no clue. I would pull the intake and check for shaft play.

I had that same sound. It was a pin hole in one of my couplers make a boost leak detector and see where the noise is coming from.

you can here mine here

It ended up being the coupler on the cold pipe that was in the fender well. so the noise was louder due to it's location

Then maybe you should get a Perrin exhaust.(nailbyt)

worst troubleshooting ever, lmao (pow)

anyway, mazda gave me a brand new turbo when mine started whistling. 6 days left on the warranty, lucky me..

i think i found it. looks like the line leading from my intake to my bpv is loose. I don't have the tools now, but i'mma fix it when i get home and see if that helps. anymore ideas?

 

[harrisonchang]

fixed it. it was the intake. I'm starting a new thread, so help me with that guys...

title --> I'm not boosting in 1st gear, normal?

 

[joghia]

What exactly in the intake? Was it just that line from the bpv to the intake?

 

[harrisonchang]

yea. loose line

 

[joghia]

Was it obviously loose; like to the touch? Or did you just take it off, put it back on and it was good? Just asking because my intake whistles too, and I'm trying to troubleshoot it.

lol now im confused. my turbo whistles but it doesnt sound anything like zuku 26 videos or anythnig u guys are posting. is it the high pitched type of whistle thats fine or is that still bad??

i looked like it was going to fall off, but it was still hangning on pretty strong. Do you know what it mean?

I took off and reinstalled my sri, and it was fine. no whistle.

For me, it's the sound air being sucked in. The sound in that video doesn't sound like mine at all. That sound sounds more like transmission whine as opposed to mine that literally sounds like air being sucked in.

check your vacuume pluming , if its high pitch noise it could be the ball bearings of the turbo going bad or are bad already.

No transmission whine here. It was air being blown out of a small hole in a coupler. in person it sounded more like one of those kid birthday party blow toys, that unrolls when you blow on it.
depending on the size of the leak/hole how much boost and the location of the hole the sound will differ
