hi, can someone please identify what is causing this noise...

i have a lengthy back story to this but i'll just post a little bit of information.

so basically this noise comes only on boost, and due to this noise the car starts knocking very badly and i lose power. when im driving normally everything is fine, when the boost comes on this noise happens and doesnt go away till i lift off the gas.

this problem is very old and im dumbfounded by whats causing this.
