Any proffered brand? What else will I have to get with an UD Pulley? Pro's Con's? I searched UD Pulley and I really didn't get anything. So some link to a thread or any thing else would be nice.

 

I am running an ASP underdrive pulley and underdrive alternator pulley also. You will need a shorter belt. Mine is a Gates K060763. If you just run the underdrive balancer, you might need a K060770

 

get the march pulley from thunder racing. Seems to be the best pulley and its fluid dampened.

its an ok mod to do.....prefered if your already doing some heavy engine work...because it can be a bitch to do

 

Thats the one I have, it seems really nice, its still in great condition, plus the set from thunder comes with all the bets and stuff.

 

If I was ever going to do an underdrive pulley again, and wanted it to be 25% underdrive, I'd go with the ASP (I have owned and taken off my Powerbond). Personally, I went with an ATI Superdamper (stock size, so no underdrive), but I have an electric water pump, a Turn One power steering pump, and an underdrive alternator pulley. I just felt like being different.
