the pulleys are actually bigger, spinning stuff slower, putting less load on the engine.
i don't like the idea at all, slowing down your alternator, charging problems may arise slowing down your power steering, dry steering in carparks may be harder and so on. i've never used them but i'm thinking that may be a problem

Most accessories are over driven heaps anyway so putting under drives on does Bugger all on how hard the steering is and the charge of the altanator.
They can be a great bolt on mod for a little extra go. Also dry steering is bad for powersteering and shouldn't be done.

Dunno about the sixes, but accessories appear to be unaffected on the 8's.
I fitted a set to mine, used the same belt, and has had no impact on any of my accessories. Make sure you put the alt pulley on too as it's not just for show, it will actually return your alt back to normal operating speed. I would imagine if you retained the stock alt pulley but changed the crank and water pump, you would lose charge VERY slightly. They are a very worthwhile mod and i would recommend them to anyone.

correct me if im wrong but i think those two extra pullys are for the alternator and waterpump so they still work the same as before underdrivers

found a few of the cheaper ones someone mentioned but you'll notice they only contain the harmonic balancer and belt, the other link contained the 2 pulleys for alt and water pump
