First of all, the point I was trying to make is that it doesn't matter whether a 4600 HP piston engine ever existed.
You are playing with a CFS simulation of a piston engine.
If you want 41 cylinders in your engine, then there is really nothing to stop you.
I am pretty sure the simulator isn't smart enough to limit you in that way.
If you want 18,000 HP, then just keep increasing parameters until you get what you want.
We are not working with real physics here.
Regarding the P-3 Orion's performance, check the NASA guide (Page 11) for maximum speeds.
