I'm almost starting to think you're trolling.
There is not a scintilla of doubt in my mind that he is trolling.
I like the VE as much as any guy, it's dead reliable, you can do whatever you want with it to ~400hp, but you can't change the laws of physics.
It's one piston (plunger/rotor, whatever) doing 6 times the work of an inline pump, with passages and components only designed to realistically support ~300hp on a 6 cylinder application, at best (stock).
The critical problem is feeding 1 piston (plunger/rotor, whatever) enough fuel to support the horsepower at a given RPM, while keeping the thing cool and lubricated while doing it.
Increasing rotor size only exacerbates the problem.
Those few who have done 500+ have had pretty ingenious and expensive ways of doing it, 1 of which was force feeding it with what was basically a hydraulic pump.
There are greater, more capable minds than mine, or yours, playing with this, and they have yet to come up with a viable solution to make 1 rotor (piston/plunger, whatever) do the same amount of work as 6.
