In a recent Hot Rod Mag. I seen an article where their project Corvette go-cart had two Sears leaf blowers complete with engines, supercharging the engine, those units must really turn up the rpm's.  JohnD

During the first big war, the German experimented with using a 200Hp engine to act as a supercharger for the 4 engines on their biggest bomber.

One of the recent Reno homebuilt class racers has used a Rotax 2stroke to run their blower.

Not to rain too much on the parade of ideas, but I'd be fearful that anything except a properly engineered blower assembly will consume more power than it will add to the engine's output. Much better minds than mine say that one of the reasons small turbines are so inefficient is excessive leakage past the perimeter of the blades, due to the ratio of the gap area to the overall area of the turbine.
