Wow, I didn't know you guys just get one pulley in your set. My set came with an alternator pulley, a power steering pulley and a new belt.
Not sure if I've mentioned this before on this site, but when I installed them in the winter time, defrosting my windshield took FOREVER in the mornings. I mean, the heat wouldn't come on for like 10 minutes, and Greenville SC has very mild winters. Before the install, it was only like 2 minutes or so for the heat to come on. Keep that in mind.
Never took it to a seperate dyno b/c I installed it at the same time with I/H/E...
If I had to do it again, I would've just gotten the UR set, which obviously nets more hp. Oh, and for the last time, the UR set is TOTALLY safe for your car...uh, I think. I know it's safe for mine.
