How far to rev this 273 commando build

Rob can you explain? I just used Google and looked at approx 10 graphs. Only 1 where they intersected close to 5250.
I read wiki and got confused quick lol.
I'm not saying above graph is correct by the way.

That graph in post #4 is incorrect. Torque and HP always cross at 5250 RPM.
