I think I figured out that these pullies are overdrive pullies. Every place I found has said that they add 10-15 HP to the engine (which probably means that only about 5 is getting to the tires right?). I have no problem with that, infact it makes me even happier because that is one less mod I have to do.

My questions is this. Several places that sell the overdrive or oversized pullies say that they are illegal in places that require emissions. Why is this? I ask because in Pittsburgh, emissions are required.

Thanks for any info..

Also is this a good mod or should I think about changing to a different type of pully? Thanks again
