the same thing happens to me. on mine it sounds like a chain going across the ground. like when your towing a trailer and you have the emergency chains hit the pavement, sorta sounds like that but its only after 4-5k.

If you had a video or sound clip I bet we could identify it in a few seconds..

But to be honest I don't know what you mean by winding. Maybe you meant whining?

Do you mean like a whistle?... A video is probably the only the any one will be able to help you figure it out.Did this just start happening or has you motor all ways made this sound?

...wonder if the "T-belt" is too tight causing "belt sing" under high RPM's?

that makes sence,it does sound like the timing belt.and yes it is a whining noise.the car just hit 100k miles.any more info would be great guys thank you

it could be any of the belts they could be either too tight or cheap belts I had one too tight it made noises then it snapped but I bought a autozone belt and it was raining and it got wet and starting whining then eventually broke

Yep, bet that "T-belt" is ready to bust on you then. Bet it's stone dry and brittle causing to whine over the sprockets at your high revs. plus, the rollers -tensioner and idler are also getting very tired as well in which you could also have bearing whine with these rollers in along with the belt.

Better think about this one seriously. good luck-DSM
