funny noise on high boost

Just working my way through a couple of issues with the new(ish) engine. Seem to be getting a funny noise when putting the boot in and pressure goes past about 70%. Car seems to run extremely well otherwise. I would describe it as a "tinny/shrill noise" , if that makes any sense. Its very...

I’ve installed krona downpipe and brand new gaskets. It was making a noise before I installed the downpipe, turbo.

ivatigoal and myself appear to have similiar noise. We havent found cause yet sorry. Managed to rule out a few things. Listen to my video and see if its the same (linkin my last post)

Strange noise when boosting

I am talking about the noise it's can be heard from the car (not the one that has the camera) while boosting. I had that noise since stage 1 and since then I have changed almost everything related to turbo (solenoids, downpipe, silicone collars) even the turbo itself. It does not have any other...

main concensus so far is that its not the turbo. I tried smoke test but couldnt find anything at low pressure (<5psi) however it only appears to happen on high(er) boost. At this point I am not prepared to run 10-12psi into my inlet or exhaust to test it for leaks that open at higher pressure as i am worried it will break something.

Idk how to post the video I have of it, but yeah. It’s definitely the same noise. It’s really irritating.

to post my video I just loaded it on youtube and linked it to the post.
On the plus side.I have had it for a few months and it doesnt seem to be getting worse or effecting anything adversely. I just worry that it might cause damage so drive around at about 70% throttle. love to know what it is though, so i can get on the loud pedal safely.

Everything is fine, no loss in power or boost.
