Agreed... I removed both of my pulleys due to this issue. At the time I had a lot of other electrical things draining my power also..small system.... and it eventually led to the hassle of going through an alternator and brand new battery.Scott95VTEC said:They aren't good for stereo systems, since they don't charge the alternator as well. But they do reduce the losses from spinning the power steering and alternator pulleys. So you do gain hp, but lose a few volts in your electrical system.
