the obx pulley set is an underdrive pulley (udp crank) the others are ovver drive they counter act each other ...

You can have it cheap, fast or good. Pick any two.
If you want it cheap and fast, it's not going to be good. If you want it cheap and good, it's not going to be fast. If you want it good and fast, it's not going to be cheap.

I wouldn't think it would "counter-act" each other. By placing a smaller pulley on the crank you are adding to it's rotational torque (a smaller circumference pulley would be stronger and spin faster). This would in turn spin your accessories faster causing them to wear out sooner. By adding a larger pulley to the accessories it would slow them down due to it's circumference increasing, and need less rotational torque to spin it, therefore helping them last longer.
You would counter act a UDP by placing smaller pulleys that were directly proportional to the change in your UDP size from factory.

Would it be best to replace the crank pulley or replace the accessories pulleys??? Im leaning towards replacing the accessories due to fact that crank pulley needs to be harmonic balanced or it would wear your seals out or something in that range when I looked at another set...drop some info..

either one doesn't mater the udp would probably wage a bigger gain cause u drop 5lbs off of rotating weight with it...
