haha, well i installed them today with test pipes and i felt alot better throttle response. they are awesome, and look great. the only thing really different is that the alternator works harder so it burns out quicker so i hear.

all of you who approve of the Pulleys, ......are you running the SS kit with all the pulleys or just the crank?
from what ive been reading it seems best to leave the others and go only with the crank?

i wouldnt put a underdrive pulley on if you intend to have a audio system, i would just put on a lightend crank pulley like cnr(crazy nut racing) sells which is oem size so it takes the factory belt, but is like 5+ lbs lighter to achieve the same results as the underdrives.

the underdriving is so mild, that unless you are trying to drive a mega amp, without a cap, or without an extra battery, it has no plausible affect on how the system charges
I've yet to see a single Z, pulley or not, need a new alternator FWIW
That being said, 2.5 years with my UR pulley....not a single issue
