Not really. The smaller engine will be working harder for longer to get up to speed.

The other thing to keep in mind is that for most of its life the supercharger is just basically rotating without putting out boost. Mercedes uses a bypass switchover valve which short-circuits the input/output lines on the blower. It basically allows the blower to free-wheel when boost is not needed.

No, it uses a clutch, identical to an A/C compressor. When unplugged it does not move at all.
