has anyone installed one of these, if so what kind of improvement did you see? also did you have to buy the underdrive balancer too?

I thought someone tried this once and noted little, if any, improvement. It was a while ago. I wouldn't expect any noticable improvements though, to be honest.

Underdrive pulleys do next to nothing on a stock motor. If you get a cam, heads and intake done, the UD pulleys might be worth a look.
