[QUOTE="B33mEr, post: 369875, member: 13609"] i think the other pulley is the alternator pulley which is a big No-No. It basically under-drives your alternator and will affect BMW's sensitive electrical system, so the aftermarket guy is right in not installing the alt pulley. I'm assuming that the set of four pulley also includes the lightened crank pulley. [url]http://www.ruff.tw/BMW/CP.html[/url] [url]http://www.ruff.tw/BMW/UP.html[/url] [/QUOTE]
