What are your riding conditions? Flat, Hilly, Mountains, Traffic, Distance, Stop lights
6T is about half the KV of a 3T motor.
Which means, that in order to get the same speed you need to double the voltage.
But like I said, its all a balancing act because it will produce the exact same torque, just a matter of how you get there.
This is a quote that I searched. I believe its from TeslaNV's MXUS 3k V3 Turbo for sale thread.
Nominal Wattage: 3,000W
Peak Wattage: 6,000w
Voltage: 48V-96V
Torque Constant (Kt): 3T = 0.8Nm/A, 4T = 1.07Nm/A, 5T = 1.34Nm/A, 6T = 1.59Nm/A
Lamination size: 0.35mm
Turn count (T): 3T-6T
RPM per volt: 3T = 11.9 Kv, 4T = 8.9 Kv, 5T = 7.15 Kv, 6T = 6.0 Kv
Stator/Magnets: 45mm
Max Efficiency: 90% Peak
Weight: 20.6lbs
Dropout spacing: 142mm (Standard) or 170mm (Fat Bike Version), or custom is possible.

I will see what I can come up with from Justin. If I remember he metions something about this, in a thread and a vid. Its been nagging me thinking about where I saw this whenever this kind of subject comes up.

When you compare two motors that do have the same fill, like the slower 7x9 with the faster 9x7, you still get a difference in the torque output off the line, because the faster winding motor needs more current to produce the same torque, and outside the motor, more current means more losses in the motor controller and motor phase leads (but not the battery leads, as the battery current stays the same).
