To all sifus and gurus here,I was adviced by an expert that one of the cheapest and most effective mod you could do to your E60 to improve performance is to change the pulleys.According to him quite significantly improve your HP.My question here is,what can I expect and would there be any long term effect to my very expensive engine?Any advice on this would be appreciated guys
