Believe it or not, there is 1 that DOES really work. That is the one made by Thomas Knight. It uses an 8HP motor, and (supposedly) can maintain 15psi up to 6Krpm, on a 1.6 liter engine. But on our 2.5 engine, it would probably start out at around 10psi, tapering down to maybe 4 or 5 at 6K.

Those are the pros, but here are the cons:

It is quite expensive, FAR exceeding the cost of the others.
It needs 2 additional batteries (24 volts, at like 400 amps), to power it.
It needs a special setup to be able to recharge those batteries.
It can only be run for 15sec max, before it will overheat.
It needs quite a few minutes to cool (and recharge the batteries) between "runs".

When automotive electrical systems go to 42 volt, some of those cons will no longer be issues. But for now, this is "the state of the art", when it comes to the ESC.

It takes a lot of power to make boost. Bottom line is that a motor which draws less than 30 amps (or even more than that) at 12 volts simply cannot do it.
