$975 for a friggen pulley? I pulley'd the super charger on my 2004 Mini Cooper S for a hundred bucks. I had both a 15% and 19%. BTW, what's with the A/C style clutched pulley on the S/C? I bet this thing is the reason some say the SRT has a slight lag and then an unpredictable huge blast of power. Why isn't this always driven like every other system out there? If you had a normal pulley on the S/C you would just change it our for a reduction pulley. Also power application would be smooth and linear.
