Only issue I'm having is that Seb had to do about 50 dyno pulls due some other issues and he said that my sc oil is black. Any ideas? Normal break in after rebuild? Supercharger going out, crappy rebuild? I'm going to change the oil and monitor it to see if it continues or if the sc starts making noise.
