Note that MSD's new digital boxes only draw .7 amps per 1000 rpm, which means you could theoretically turn 8000 rpm an still only draw 5.6 volts.

I guess you meant to say and only draw 5.6A.
But if the unit draws a maximum of 6A @ 12V, that would mean a current limit of 4A @18V assuming 100% efficiency. So the RPM limit when using the "new digital box" would be down to 5700 rpm, assuming 100% efficiency.
Small DC-DC converters are typically 70-80% efficient.
