UR = underdriven right? I'm just looking to add some speed without throwing an exhaust or test pipes on..

 

What are the downsides to the UR underdrive pulley for the Z? I suppose I could search, but I'm feeling lazy.

 

UR = Unorthodox Racing

They make underdrive and non-underdrive pulleys.

 

Ohhhh. Yeah they do, I was just looking at getting a light weight set. I've researched the underdriven ones and there've been a few problems with them. I guess it won't spin the alternator pulley as fast which doesn't charge the batter as well, leading the batter to a much shorter life..that's all I know about the underdriven ones...people say they "screw your engine up"..but they don't really supply any evidence or how they actually do..but i'm just going to go with the light weight pulley set.
