I just installed a new stage 2 clutch kit about 700 miles ago. I drive without hitting boost for about 500 miles for brake in. I got on it hard the other day and when I got to about 10 psi boost I heard a loud banging sound. Could hear it over my load music. When I got home I realized my clutch was making a lot of noise. It gets better or worse depending on pedal position. I can still shift gears if I don't push the pedal all the way. If I push it all the way down it grinds and can't shift. The chatter is there all the time but like I said it changes depending on pedal position. What could it be? Damper springs? Or something else entirely? Please help.

Good morning,

Sounds like the pressure plate or the throw-out bearing.

You will need to tear it down and inspect the clutch itself.

Can you upload a video of the noise so I can hear it?

You are welcome.

Make sure you either have the flywheel cut or replace it.

Sounds good. I just do not want it to chatter when you let the clutch out.

If it was that bearing you would have a roaring noise from the bearing.

Okay, then most likely there is no input bearing damage at all.
