Don't quote me on this but I think a possible draw back is at low rpm with a high load your engine could stall. The alternator might not put out enough juice if you have a lot of demand like the AC going while sitting in traffic.

Perhaps those are issues with other products out there, but not with the 601 Pulley. It was engineered and tested to not adversely effect the alternator charging, cooling and AC systems. The pulley has a 10+ year track record without fail.
