Just read through that link and what car battery or alternator can put out 350amps!! Gonna need some 0awg wire just to power it!
Horsepower ratings for typical starter motors here:

Multiply the hp figure by 80 to get a rough current on a 12 volt system (this accounts for motor inefficiency).
A typical diesel engine with normal starter gearing requires about 1/20th the engine power in order to start it.
For example, a 50 hp engine needs about 2.5hp (200 amps at 12 volt) to start it.
So my 115bhp Multiwagon would require in excess of 400amps to start the car(if I've done my the maths correctly).
While the car is easily able to produce this amount of power for the 2 or 3 seconds its takes for the car to start I'm not sure how the cars electrical system would cope with a huge 350amp surge everytime I put my foot on the accelerator. Some newer cars cut the engine when the car comes to a stop and automatically restart it when the accelerator is pressed. This must drain a lot of power but they seem to cope ok so who knows it may be possible one day.
Yes an electric turbo does increase engine performance but at what cost?
BMW use a twin turbo setup, one large and one small turbo. Small turbo for producing power at low engine rpm. Perhaps this electric turbo could be used in a similar setup on future cars, small electric turbo for low rpm power?
Look on the bright side, if electric turbos are ever used as standard all the 0awg wire will increase its scrap value ...
