It's trivial to put a high-power electric motor into a car. It's very difficult to supply that motor with enough juice to actually sustain that kind of power output for a reasonable period of time.

For reference, 800HP is 600kW.

Not that trivial. The Tesla P100D can break 600kw now, but has only been able to do it in the last month or so.
