Good info thanks! Had no idea that one belt controlled the accessories AND the blower. Says that it operates the supercharger at an engine speed of 2.1 - I assume this is 2100 rpms so does that flat out mean you're beginning to make boost at that rpm? Cause typically you have to lean into the throttle at least 3/4 of the way to start making boost. I could drive my Cobra at 65 without making boost as long as I kept under 3/4 throttle.
