Superchargers are mechanically more complex, what with needing a drive.
However, they produce boost without throttle lag, and also are able
to produce boost at low rpm, where turbos have difficulties.

F1 cars are typically run at high rpm, and thus high exhaust volume, so
the low rpm bit is irrelevant.

Lancia produce a few cars with supercharging, using a system known as the
Volumex compressor.


Could it be that superchargers, being based on engine rpm vs. exhaust
volume, are not able to develop such high boost pressures?
