Underdrive pulleys

[GnTooFast4u]

I heard they are no good for our cars? Are they?What are the best kits out. Are they worth the money. How much of a difference do you look at?

For the money they are not worth it. You only get like 10 hp out of a pulley change. In my book the money is better spent on something else.
