If I have a motor that large and powerful enough to
move a car at 60-70 mph for daily driving at a =91low=92
voltage 70-90 volts, but then I want race it over 100
mph at a =91medium=92 voltage 110-120 volts. How should I
deal with the advancement of the motor?

Just design the car for racing parameters. You can even run it that way on=
the street. The easiest way to make the switch is to use the Valet mode s=
witch on the Zilla and simply make one setting for Max battery amps you int=
end to draw and make the "vallet mode" with a more sane battery current dra=
w i.e. not more than 200-300 amps for daily driving.

The big problem with arcing happens at high voltage and high current.
Chances are you won't see the really high currents in street mode, so set
for racing and leave it there.

It will be slightly less than optimal in street mode, but it won't make a
measurable difference.
