Help! Weird sound when releasing clutch and giving gas (Video)
My 2016 c7 z06 started to making a weird noise when letting off the clutch and giving gas. Anyone know what it can be? Supercharger pulley?

I noticed it appears in the video the sound only occurred (to my deaf ears) while you were turning in 1st half of video. Maybe you had the steering wheel pegged all the way to the stop. I've never pegged my steering out due the wheel chatter/hop we have occur, whole different subject. If that is true, I would suspect perhaps a power steering sound instead of clutch. Hopefully other experts (I'm not) will chime in soon, I'm curious.

Very similiar noise myself, intermittent and dealer hasn't been able to make it happen. Mine seems to be mostly when it's cold, but does happen when hot. I've seen another thread a few weeks ago about the same noise, hope one of us gets it figured out.

Are you referring to the low pitched sound that sounds like the recordings in the forest of Sasquatch’s mating calls? I bet that’s the power steering or something in the rotating assembly of the accessory belt or pilot bearing. I would bet it’s the pilot bearing. It’s still under warranty. Get it documented with the dealer. So if they don’t fix it. You have document trail and force the dealer to cover it even when it’s out of warranty.

Weird, sounds like some of the newer Shelby’s rear ends. They recommend doing several figure eights in a parking lot to quiet the noise (funny thing is it worked). Good luck, let us know what they find.

Ah, the ol' clutch hoot, or "barking seal". It's very common with the metallic clutches, less so with the organic compounds. Usually a few really strong hole shots will make it go away.

Clutches tend to involve various sorts of compromises, just like brake pads, suspensions, engines, and even brake fluids.

Definitely not isolated to just big HP cars.

Anybody ever get a dealer to figure out what the clutch noise is? Mine has done it for a while now and seems to be getting more frequent. Hopefully the next time I take it in for service it will make the noise and they'll actually look at it.

Flush the clutch fluid. Yes I know it sounds stupid, but it will fix the noise.

C7 16 Z06 M7 Clutch Squawk
I agree with the clutch fluid fix several others have noted. My 16 Z06 M7 started making the squawk heard on several of these videos. ~15K miles. After reading the forum threads on this, I went after the fluid fix. FIrst thing I discovered was fluid LOW. No leaks no drips. As far as I can tell no one has ever checked the clutch fluid (my bad) and it may have been low from the factory. Filled with DOT 4 fluid and, so far, have not heard the "Clutch Squawk". Clutch actually feels smoother on engagement in 1st as well.
