With turbo kits as cheap as they are, why bother with this mess?
And regular old turbos are only going to get better. Companies are still making significant improvements in efficiency with each generation. The Mazda 2.3L turbo feels like an old 4.0 V6 at every rpm but it kicks butt in efficiency.

Did you miss the articles with higher end brands using electric superchargers?
Right now the big limiting factor is a 12v electrical system, it requires too many amps for the supercharger to work well. Bump it to 48v and it suddenly becomes more efficient and useful.
