Hi! I recently replaced the „Torsion Isolator“ on my 2010 XKR

Now at around 3000 rpm if you press the throttle (around 70%+) you hear a metallic „screech“
It has to be the Supercharger because the noise wasnt there before i got the Isolator changed & if i press the throttle only about 15-20% and get over 3000rpm there is no noise but i don‘t know what it can be. Do i have to replace the snout? The old Isolator did a little bit of damage inside but it wasnt much to be honest.. car still runs perfectly fine & no problems except this noise

Here is the Video :

I really couldn't hear the "screech".

 

nor did I

are you sure it isn't the drive belt slipping?

the dashcam is not that good unfortunately. I tried to record it with my phone but i couldnt hear it either. This was the only Video where i could hear it. Its directly after i let off the throttle.(but even with 100% volume still quiet) i thought it was the sc whine but it cant be. Slipping belt idk but its more like an Metallic noise

You can hear the noise in the video when i passed the first white cone on the right side

 

sorry, maybe the compression (U tube) has removed the high frequency sounds but I do not hear it
