There's a guy at my work trying to get rid of his UR pulleys for cheap. Does anyone have experience running the Unorthodox Racing underdrive pulleys on a car with an upgraded stereo? I have a total of 800W of amp technically, and the pulleys say they're good for 600W. Wondering if I'd be in risk or running out of power.

 

Oh yeah...dont do it buddy

 

You'd have a lot more problems to worry about than just that... Do a search and then decide.
