My Belt keeps on slipping at high rpms and I can't firgure out why. It used to never slip until I replaced the alternator. I have the asp crank and alty pully...they were fine and never slipped on the old alty. So I got a new (3rd one) alternator and it still slips! I have replaced the belt (3 Times), The belt tensioner, all the pullys roll free...I put the factory alty pully on and it did the same...I even tried belt dressing but nothing helps...there is belt residue all over the motor and I can floor the car and watch the volts go from 15 down to about 6. The belt is a 755k6...I tried one size smaller and it didn't help either. So if any of you have any ideas i'm open!
