I am in the datalog process of my build. Over the past 12 months I rebuilt my engine and made a custom twin turbo setup. I've got a single knock sound at around 3200 rpm or so that I can't pinpoint. I'm hesitant to push it any harder.

Any ideas guys?

Brakes were hanging in the video due to hydroboost issue, I've sorted it out. That's why the rpms are so high.

14 second mark you can hear it. It's from the engine bay and is not cause by speed, only higher rpms around 3200. It will do it more than once while driving too. It's always a single pop/clank.
