Huffed at Two Speeds! New Supercharger Features Transmission

This is truly a cool piece of hi-po tech geekery, and it's so simple, we don't know why anyone hasn't tried it before (or at least why we've never heard of it). The pocket-protector advocates over at Atonov have come up with a centrifugal blower (which operates like a crank-driven turbocharger) that uses a transmission to change the rotor's speed depending on engine RPMs, resulting in improved boost matching throughout the rev range. Totally donk-stompin' awesome.
