What is this strange noise?

Ok, so when accelerating hard, there is a like a tire screeching noise, but tires aren't spinning. When driving high speeds there is no noise, only when accelerating hard.

Here's a video, I hope you guys can hear the sound i am talking about.

Any ideas?

I dont hear screeching noise, maybe a slight whine. If you dont have a supercharger on there I'd go with belt slipping a little. check you belt for cracks and normal wear and tare. Also check the tension on your adjustment pulley just to be safe.

Sounds as though it's coming from the rear

It kinda sounds like intake noise in that video. Do you have a cold air intake or something like that?
