superchargers?

[Gumby1008]

Hi Im at university and we are building a Hill climb car, not dirt hill climb a road hill climb. For those unfamiliar its a very short course, rarely taking more than a min, on incredibly windy tight roads. Our current choice of engine is a Hayabusa engine. Most hill climb cars will run hayabusa engines, and more often than not supercharged. Due to the way hill climbs are, turbos are simply useless, you need your power THEN any lag is unacceptable.
Anyway what we are considering is something that I don't think has been done before, a twin screw supercharger. Does anyone know if it has been done before? they are certainty available in sizes small enough to work on a hayabusa even as low as .62l per revolution. If someone knows if it has been done that could save a lot of time and possibly prevent an engine from being ruined. Any information that could be relevant would be much appreciated.
