I just spoke to Angelo about a few things I had concerns about with my new SDS'd car, one of them being the strange rattling/clacking coming from the blower. He said this is NOT the normal supercharger break-in sound, then he asked me what type of oil I used. When I told him Mobil-One, he told me to go drain it and put in Castrol GTX. He said that superchargers don't work well with synthetic oils. I'm draining my oil now, and will let it drip while I sleep since I just got home from work. I'll post back up here after I change the oil and see if that makes any difference.
