I had these on my 89 gt and they completely ruined my alternator and battery. I put a new one of each on and they ruined my second alternator. Of course, this time I caught it before I ran the battery down. Warranties are nice for this too. I didn't have to buy that third alternator, just traded. After that, I took the pulleys off and sold them as quick as I could. I could not be paid to buy another MAC product. The pullies didn't make any noticeable power on the street anyway. I hope this helps you on your decision.
