    Question Strange Noise Coming from Engine/Turbo..Help?

    I drive a 2012 wrx with 11k miles. Stage 2+ Cobb intake and downpipe. This has been happening since I went stage 1+ that I can remember (8k miles?) I took this video, but you might have to turn the volume pretty high to hear it...Its only in 4th gear for some reason...any ideas what it could be? Any help is appreciated..

    Thanks

    Almost sounds like a rattling heatshield.

    Interesting...I'm gonna change the oil tomorrow, so I'll take a look, but I'm pretty sure I took off all of the heatshields on the dp install. I'm worried it may be coming from the wastegate...its like a loud screech =/

    So I found a video that sounds exactly how it sounds in real life...In case anyone else runs in to this - this is what it sounds like: True Compressor Surge - YouTube and from research the fix seems to be an aftermarket bov(bpv preferred) that is adjustable.. Seems like people with HKS SSQ just loosen the screw and it goes away.
