To all that have underdrive pulley's. I need to change my crankshaft oil seal and thought while I have it apart I might put on a new pulley. What are the pros and cons? Where did you buy it from and how much? Do you regret putting one on?

 

Well some people complain about the alternator not charging enough and ending up with dim lighting and things like that. So since 85% of the benefits are from lightening the pulley and only 15% from underdriving, why not just get a lighter pulley that's the same size as the stock one and have zero headaches. You can even use your stock belts.

I don't know if people have had trouble with the Unorthodox. But I know people have had problems with the motorstorm.

 

I just put a underpulley on my car about two weeks ago and I have no problem with my alternator, no dimming of lights with the my music up and heater on high. . I got mines from Motostorm for $90 shipped and I think it was worth it.
