A “turbo” driven by the crankshaft or any other mechanical means is called a supercharger. They provide much more rapid power response and have existed since the early 1900’s.

Technically correct. The ones I was referring to use a compressor wheel and housing just like a turbo charger and run off the crank. Technically, they are called a centrifugal supercharger. They are not the positive displacement type pumps (Lysholm screw rotors) that most people recognize as a "Supercharger"..

Those aren’t new either, they’ve been around since the late 70s at the very least.
