Electric Turbo!

I saw that Roadkill episode, too funny!

I'm thinking LI batteries to power the turbo. only need it rarely and for relatively short bursts, batteries kept fully charged all the time with a 12 V LI charger tied to the car battery.
Supercapacitors. Charge up fast, discharge all they got over about a 30 second span into a 12v device with huge amps. Trouble is pumping a constant 9psi into a running vacuum (motor) take a grip of power in itself. There is no free ride. Dont know why they dont just inject compressed air out of a tank instead of having the motor draw it in. Instant power, supercharger like response with no parasitic moving parts. Its called CAS, compressed air supercharging and it isnt 'new'. 850 HP on 10 psi on 91 octane. Whats on the lift at 1:59?
