Hmmm...not specifically.

Roots Superchargers are belt driven from the crank, use spiral screws to generate pressure. They are typically great off the line and build immediate pressure, but tend to peter out on top due to heat generation from poor adibiatic efficiency. Centrifugal Superchargers are a middle ground between roots chargers, are also belt driven but use a similar mechanism to a turbo as it uses a vane wheel to build pressure. They build pressure a little slower than a Roots, but are more efficient on top. They both respond and build pressure quickly since they are mechnically dirven, versus being exhaust driven.

The turbocharger, which is exhaust gas driven, can be a little laggier than a supercharger, but modern turbos are lightyears beyond old units. They spool very quickly, typically can produce much higer pressure than a supercharger, but also require more fabircation, since you ahve to plumb the exhaust system for them.

There is no right answer, but assuming your tiny motor is built to rev, I'd go with a small frame turbo like a Garrett GT2056.
