They are actually smaller than stock. As a result, they spin your AC, alternator, PS pump, ect., SLOWER. IMO, not worth the hassle. Besides the expense, there's the chance of a constantly low battery because of insuficient charging from the alternator. As far as gains... you will notice a gain only because you spent the money. In the real world, I doubt it's very significant.

<sighs> no, they are bigger. if they were smaller, they would spin accessories faster, in effect losing hp. the crank underdrive pulley is smaller
