BAD made one.They are still in business, I just ordered a 4.08 rear diff for my Q from them.(Had to put it on hold now for a month or two as I now have a rear hit I need to fix first:(..)It's an on again off/again thing for production for the SC right now (hope I am not giving away secrets I am not supposed to fellas).
There are supercharged Q's out there (AGM drives one) but that one was special made rather than from BAD.
Many feel that s/cing all aluminum engines is chancy, but if an all aluminum engines can be successfully supercharged its ours, with it's six bolt main bearings and closed deck construction.
