A chemist would call that horsepower 'Quant Suff' in my case. EV racers
wouldn't - just saw a movie of the EV drag racing down at Hagerstown MD
and to them, 1000A drawn from a 300 or so volt pack is not enough.
There was a rail type in that movie and when the light flashed to go,
that darned thing was just quietly *gone*.
