I'm sure others will say it too but, if you like to push your car...go to a track.
Doing it on the street simply puts your life and others around you in dangers way; simply because other drivers don't expect a car coming around the corner at 145mph and no matter how experienced one may be you can't exactly have total control of a car skidding from 145mpg either when your wheels lock up or you hit a bad patch on the road.
...back to the noise in question though, i doubt a belt would make that sort of noise but if you haven't changed them it's not a bad thing to do so. I'd probably side with the culprit being the pulley now though...
