- It depends on how the engineers want the turbo to behave. Some turbos
- are set up to give a real peak-y response, and some are set up for a nice,
- broad torque band. SAAB were the first to put a practical turbo in
- production cars (1977), before this they were used for only the high-end
- boost you mention.
-
- A turbo has lag when you stomp on the trottle, but this is a minor inconvenience.
- The biggest benefit of a turbo over a supercharger is that the turbo only
- wastes fuel when turbo-stomping, where the supercharger gives uniformly
- crappy mileage.
