I did a bunch of reasearch on them a couple months ago. In theory they sound very good. The efficiencies approach turbos. The problem is that they are using Holset compressor housings. Because they are meant for diesels, you are only in an efficient part of the map for a very short amount of time. The maps are very "thin." The result is a whole lot of hot air.
Once Rotrex starts using standard compressor housings, things should get interesting.
