[QUOTE="Robert Stanton, post: 555559, member: 62776"] I hate to sound ignorant... but can you explain this to me? What exactly does an under drive pulley do? I read the previous post on this, so I understand that it somehow causes periferal engine components (alternator, AC, etc.) to run slower... but how exactly? And what effect does that have on those components, or the engine itself? Besides the performance gains, what sorts of changes would one see with this? What effect might this have on maintenance or the vehicle's lifespan? Thanks for any additional info. [/QUOTE]
