Screeching Sound Near Redline

I've noticed whenever I accelerate under WOT to redline I get a fairly pronounced screeching sound. Was thinking it's just the turbos or MPE, but kinda sounds weird to me, anyone else notice this?

Ah yes, does sound a little like tires screeching. As long as it's normal, I'm happy lol.

I uploaded some footage from my dashcam in the below link. Not sure how well this website works, I may upload to YouTube later if it's not viewable.

Posting a clearer video to show what I'm talking about, does this sound like everyone else?

Doesn't sound right.
Sounds like something is rubbing during high rpm vibration and torque movement when you floor the car.
Try to hit it close to the redline without punching it, does it make the same sound?

Tried driving around redline in 1st and 2 gear today and there isn't that sound. Seems to only happen when I floor it

Not yet, I'm still 700 miles away from my first service, so will have them take a look at it then.

I'll mention this to the techs, I hope it's not too difficult to locate and fix if that's so

This is the quandary... telling the SA and/or techs that the sound happens when red-lining the car.
If hope they take care of you, but have a sneaking suspicion their default answer will be to "not do that".
Tell them the car is supposedly designed to accelerate quickly and that you paid extra for the MPE because you enjoy driving the snot out of the car.
