The intersection of hp and torque can still meet at 5250 rpm but be higher numbers.

Are you talking about the torque curve moving and hp numbers staying the same? Are you saying that by changing cam profile you can move the torque curve without effecting hp?

By the way Throttle Crazy is my brother so I have to give him a hard time.
you were trying to make a joke, but the fact is that torque and horsepower intersect at 5252 rpm, horse power was invented by James Watt's after observing that a horse could lift at a rate of about 550 foot-pounds per second for about an 8-hour shift. horsepower = torque * rpm / 5252

That's not a shift, that's an expansion or a change. A shift denotes moving the exact curve either up or down the rpm axis.

Another example of a change, being an expansion, not a shift.

And before you say it it shifting up the axis, stop. Because since you can't make hp at zero rpm, the angle of the torque line will be different to originate at 0 and 0.
