1950/10 is too hot. 55amps is nothing for a car. (remember, even the mamba-max controlers are for 1/10th vehicles and can do 100A continues.

but with 8s lipo the 1950/10 is still around 40000 rpm.

bottom line;

your theory is okay, the more volts the less current is needed to get a certain amount of power.

The maxximum power of the setup on 8s would be 1628watts, while a 9920 on 6S can deliver 2200 watts.

if you want to go with that controller i would look into a 700-750kv motor.

with the current setup you are planning on gearing it for 56 mph.
