How far to rev this 273 commando build

It's over my head, Steve, but it has something to do with physics. Every time on every dyno run torque and HP always intersect at 5250. I don't know why.

Steve, I found this. I got lost pretty quickly, but maybe it will help. lol

Why does hp and tq crossover at the same point always? - Power and Drivetrain

Torque x rpm / 5252 = Hp
Torque x 5252 / 5252 = Hp

Cause at 5252 rpm's the rpm and the constant of 5252 in the formula cancels each other out. The cross over has no significance in the power curve of the engine.

If measured in Kw you'll have a different cross over point, you could figure out how much work you can do in a minute and come up Rob power formula Rp which would have a different cross over point but doesn't matter if you use Kw Hp or Rp they will all have the same curve and be mathematically comparable to each other.
