I really like the KJR setup for the simple fact that since it is not underdriven you can use it with a supercharger. But, if you are going all out NA every bit of HP matters so I went with the UR Pulley Set.

Do you have noise from your UR 3PC Pulley Set? I cant handle squeeks, rattles, and so on! I do plan to stay NA, but I plan to throw a DVD screen in the cubby hole and I have a custom sterio as is, would underdriving be ok with stuff like that installed?

i just read that the harmonic dampner pulley problem does not concern the Z as it is internally dampened...

So not one of the problems described in the article affects the z engine?

If that's the case the 5-8 hp for 250 might be worth it..

I don't have any noise at all that you can hear from the cabin. I run the 3 piece set so maybe that works more quietly? Alot of people have found a slightly narrower belt will eliminate all noise but I think a polished aluminum will always be "louder" than stock. Ah well, I don't notice any noises... Test Pipe rasp is far worse.
