WWII propeller driven aircraft used turbosupercharger systems. This put a turbo in front of the carburetor, with a centrifugal supercharger after the carburetor. Quote from link below:
"Turbosuperchargers
1. At the present time, turbosuperchargers are used in series with geared superchargers, the intercooler and carburetor being located between them. In this way, maximum use can be made of the advantages of each type.
2. A geared supercharger has one obvious advantages of compactness, lightness, and ease of installation. The greatest disadvantage of the geared supercharger is its application for high-altitude flight is its inflexibility of speed. If it is designed to develop sea-level pressure at 20,000 feet, for example, it will deliver an excessively high pressure at sea level with the carburetor throttle opened wide, so that the throttle must always be partially closed for low-altitude operation. "
The turbo is used for its flexibility, the super for its compactness and light weight to add extra power.
I really can't imagine what use such a system would have in an automobile. The WWII aircraft needed to operate around 30,000 feet so forced induction was necessary.
