You are right when applying the concept of turbocharging to cars. On most turbo'd bikes though, the turbo is so small that it spools virtually instantly, and the powerband is pretty broad. I've seen some vids of Cycle Logic's turbo 1000RRs and they're pretty f'ing fast at the strip, and I think I remember seeing a dyno sheet too at some point, but I don't remember exactly where peak power was made. But the powerband was linear enough that the bike was scary fast.
