Need MOAR POWER!!!!
Im going to go out on a limb and say a full reconstruction of OEM voltage (a la 24-48 volts) is a little ways off in the future. Think of the poor aftermarket parts suppliers lol and theres just sooo many places to lose energy in a system like this its crazy!
I suppose they could make it like an aircraft (which btw have 28 volt electrical systems) and have the starter also be be a generator when required to run the turbo at high throttle settings...
I'm more than willing to see it in action
