I thought I came across calculations based on the SC pulley's diameter that showed that it was equivalent to <178mm crank pulley in terms of overdriving the supercharger (and that was with the 65.03mm of the 1st gen pulley, not the 65.3mm measured from newer pulleys). Then again, my memory's never as good as it was. I'll have to dig that up somewhere.
