My bad... I misunderstood your post then ... it read to me like you were posting your estimate for his conversions acceleration was only going to be 0-60 in 30 seconds.

I don't have a efficiency map of the controller and motor Wayland is using... So, Maybe I missed something else then as well ???

I thought most motor controllers and such were more efficient closer to full power ... and the high power rated batteries he is using should have very small Peukert k values for battery loads... and the longest range would come from operating the whole system at it's peak efficiency points as much as possible.

For Wayland's setup ... from what I read ~112kw.
19.2kw is less than 18% Load

18% load is the system peak efficiency point? ... that just seems to me to be an odd / weird point for peak efficiency of this system... so I guess I missed something else??
