Turbo Chatter

[Omari1996]

Hey guys I recently saw on another thread someone talk about “turbo chatter” sounds like the turbos trying to chew rocks. I had this noise pop up on me after installing primary+midpipe combo from Ultimate Performance. So to me “chewing rocks” sounds terrible. How can I resolve this? And if left like this for to long. Is it damaging the turbos?

You have a soundbyte of this chewing rocks?

This is minimal. Usually a bit louder especially after car first starts up.

sounds like an exhaust leak. i'd check the primary + midpipe install before I looked at the turbos themselves.

That squeak is definitely not an exhaust leak, and it's at a very strange time (right in the middle of accelerating through a gear) to be a BOV release.
That's a strange one. It could be a wastegate actuator being noisy for some reason, or a BOV malfunctioning. I'm no good at diagnosing that kind of stuff and seems you'd need a rolling road to really do much. Or folks with more experience with turbos will likely have some ideas.

The exhaust note, in the recording, does not sound unusual to me. But noise diagnostics over the internet are not exactly reliable.


Do you have a boost gauge? Would be interesting if that squeak is happening at a certain charge pressure. Might be the stock BOVs having trouble holding. Also since we have the selector solenoid connected to the top of the BOVs, if that solenoid messes up then the BOV will have vacuum instead of intake pressure on the back side of the piston.
