When running at wide open throttle, there's a pronounced squealing noise which sounds like your typical engine belt squeal. It seems to last for about 2 seconds then goes away. It only seems to do it when nailing it from highway speeds after the rpm's get to about 5,000 rpm's. While lookin under the hood, it's looks like the belt is deflecting & rubbing against the front engine cover between the alternator pulley & the bottom pulley on the far right side. I thought this might be where the noise is coming due to the black marks on the cover. Anyone know why the belt move deflect side-to side more than the 1/4" gap between the belt & front engine cover to the point it hits the cover ? My car is a 2001 GT w/auto trans. By the way...I last noticed the noise while easily pulling on a co-workers recently purchased 2003 5spd GT on our way home. Granted I have some basic bolt-ons & he was bone stock.....I was still surprised. Your ideas are appreciated.
