Last night I finally got around to replacing (upgrading) my supercharger serpentine belt with a new Fleetrunner Gates K080505HD V-Belt belt. It's about 1/2" shorter than the stock belt to better match up with the smaller supercharger pulley. Took all of 5 minutes by using the 17mm wrench, loosening the belt tensioner, and swapping the belt. I can't believe the garage charges $120 to do this!
Here's a quick little video of my new HULK colored belt ;)
If you get this belt on Amazon - it's over 1/2 price of what most stores sell it locally for. Unbelievable!
