I thought the F1 cars just used dual turbos, both
fed directly into the intake manifold.
Compounding is one turbo feeding into the second,
so that the second on is already picking up
significantly boosted charge. If I remember
right, the Germans experimented a lot with turbo
compounding on fighter planes in late 1944 and
early 1945.
