Is More Flow Better, Is The Smallest Intake Port That Flows The Most The Best

Oh dear. 400hp is available at all times, is it?

Please explain this to us:

How can an electric engine be rated at 1000kW regardless of RPM???

We all know 1kW = 1.34HP so how does that work?

Explain.

EDIT: It doesn't matter. We're just going around in circles now. There's nothing else I can add.
can you explain to me why an engine making similar tq at different rpms say 500 lbs-ft @ 3500 rpm & 4500 rpm if I'm wrong it ain't per revolution and why does it make same tq and more hp at 4500 rpm and what does rpm have to do with all this?
