I believe he's talking about the pullies, not the balancer. Accessory pullies dont have any issues that would cause concern other than the alternator not charging until the engine reaches 1800'ish RPM.

The alt and PS pullies will probably net you about 3 - 5 horsepower. For some people that can be substantial. From a cost per dollar standpoint it is right in line or better than most other mods. At a certain point in the quest for more horsepower it becomes more about many small improvements.
