Will a underdrive pulley rev quicker?

Looking at the BBk pulley in jegs for 69$ that is cheap for a few hp i think, but what i want to know is how does it affect everything else ac and things of that order? Also, does it make it rev quicker and will it help any iam just trying to add some more speed parts for cheap. ws6.com they got .7hp and 6.5 torque that is not bad ever little bit helps right. well thanks u think a 1 inch drop and long tubes work out ???

Don't know for a fact, but I thought I got a bit more throttle response when I installed the UDs.

Theoretically, you'd think that less drag on the engine with UDs could produce that effect.

As far as less powertrain losses to the RWs, it is probably minimal, but every little bit helps.JMHO.
