superchargers are much more expensive/difficult to setup AND they aren't very efficient. If nothing else, you would have to have a drive system coming off the crank, which would be very fragile, make the bike engine wider. Not what you want on a dirt bike There is no lag whatsoever with the smaller turbo's. Literally, cruising at 30mph, I have 3psi showing. I get 3psi just by blipping the throttle in neutral. You can't compare it to any car you've ever driven.
