ok i was talkin to a friend and he was telling me that i should swap my ls crank pulley for a b16 crank pulley, he said it would rev faster and get through the rpm's a lil quicker. so i was wondering if this is tru. and if so whats the good and the bads about it?

thanx

 

a crank pulley wont do much by itself. if you get a complete set of underdrive pulleys then you will free up horsepower. i dont think you will notice your engine revving faster.

the tradeoff is the loss of power in your electronics such as air conditioning, headlights, stereo, etc.
