I have a couple questions for you folks running underdrive pulleys.

1) What brand do you use?
2) Do you like it?
3) Do you notice any problems (AC not as cool, battery problems, etc.)?
4) Any oil leaks?
5) Any hassles getting warranty work done?
6) Was changing the pulley easy and did you need a pulley puller?
7) Do you notice any positive effects (dyno results...miles increase..etc.)?


Side question: Anyone running the stock size (but reduced weight) version pulley? I'm a bit worried that my A/C won't work as well (living in TX this is important) if I go undersize, but I know that one brand does carry a pulley that is lighter, but retains the same diameter as the stock pulley.

Note that I've run underdrive (and overdrive for the supercharger) pulleys before on a Ford SuperCoupe, and didn't notice much difference, but they weren't the light weight ones like those of today.

Thanks!

 

hope these help you...
