stillen supercharger belt tensioner

I replaced my SC belt a couple weeks ago. I used a crow's foot socket and a 3/8" extension to get it down there from the top. As mentioned, make sure you loosen the pulley bolt before loosening the tensioner. It's probably easiest to cut the old belt off. Then remove the idler pulley, and loosen the tensioner bolt by hand. it moves a lot faster that way. Then get the new belt on the pulleys, and fit the idler back on. Then start tightening the tensioner 1/3 turn at a time. Once the idler is back on and the tension is pretty good, tighten up the pulley and double check the tension and you're done! It's a mega pain in the ***, but doable. Good luck!
