Sorry, kind of outside-of-topic to Subarus (unless Subaru is thinking of
using such a system, but I have no direct knowledge of that). Looks like
an interesting way to boost low-speed performance. Wonder why no one had
thought of it before? Unless it was simply a matter of computer
technology catching up to allow it to happen now. Looks like you can use
it in conjunction with turbochargers. The electric supercharger will
operate at lower speeds, thus not having to worry about turbo lag. The
turbo will operate at the higher speeds, of course.

CPT’s VTES electric supercharger shows impressive results in a
Volkswagen Passat!
"A company called Controlled Power Technologies is offering something
new called a VTES, or Variable Torque Enhancement System. It’s basically
an electric supercharger. There are alot of people who try to install
fans in the middle of the car’s intake tract and try to call it a
supercharger, but this is a proper compressor that can spin
independently of crank speed at rotational speeds of up to 70,000rpm.
CPT has installed it on various test systems including a 1.2 liter
turbocharged engine. The VTES electric supercharger is meant to
complement the existing turbo. CPT reported an increase of over 50% in
torque at engine speeds below 3,000rpm. I guess what it does is
compensate for any turbo lag there is at low engine RPMs, allowing the
turbocharger to be larger than it normally would have needed to be to
spool up that quickly."
