i hear that the more power accessories you have the more drain on your motor, its charging system, and its performance. and i also hear if you use a different belt (exclude your ac compressor, and power steering) will add power. like the reverse of a supercharger> how the belt hinders even more power, the s. belt also hinders power < remove the belt more power. granted some things will have to retain its section on the s belt. but will non use damage either of these systems ( the ac and ps)
