From the shape of the box, it looks like this is a twin screw, right?
I wonder how well the stock computer program would work with it... if you just use an oversized Focus MAF to give it a good consumption rate signal, it might not work too badly.
The ideal blower I dream of would be a centrifugal compressor powered by an electric motor, electronically regulated by a pressure sensor to provide just the desired amount of boost... like, from mid to max throttle, the boost would go smoothly from zero to your desired limit, with extra spin-up power being applied when the throttle opens rapidly. Both SC and TC blowers consume more engine power than you need most of the time, in order to have enough when you do need it. An electric design should, in theory, get more horsepower per gallon of gas than either... especially if combined with a WOT alternator cutoff.
