Yes you can, by simply preloading the engine (brake torquing), but the beauty is you don't HAVE to. You have boost (all of it) within milliseconds of throttle tip-in with a supercharger, where with a turbo, you HAVE to preload to whatever rpm the turbo spools at. If I preload to say 3500 rpms, I just spin forever, even with siped tires aired down on a prepped track. I'd have to use slicks with a Turbo. The beauty of the SC is the instant boost with no lag.
The reason you see a little boost on the non-preload launch vids is because I have the brake on and I'm just tickling the throttle. With the BCA adjustment, you just THINK about touching the throttle and you have the beginnings of boost.
