Nor does Brent know what the word generalization means, but so be it.

Brent, it is clear you can't breakaway from your trick engine builds which are clearly not in family with the majority of engine builds. Your dyno charts are a good example of this, you start recording at 3500 or 4000 RPM and have stated loading the engine at lower RPMs "will suck the guts out of the motor" ... enough said.

Revving faster is not a difficult concept to grasp, time to a given RPM is all it is.

Here's a curve ball that I expect will have you scratching your head for some time. Take a figure skater who has started a spin with both arms outstretched and one leg. Did you catch the Sochi olympics? The energy put into that spin will dictate the skaters RPM based on the rotating mass of that skater. Now that skater pulls in the arms and leg and WHAM quadruple the RPM! I'm also willing to bet that skater didn't loose any weight during the spin. Your bob-weight argument has some relevance to the big picture but not much, and you don't understand mass versus weight. In this case rotating mass = how that weight is distributed from the center axis of rotation and is a huge multiplier of RPM as shown by that skater who decreases rotational mass by pulling in the limbs.

I know you won't get it, I don't expect you to get it, but thank God there are engineers out there putting that simple law of physics to work for us everyday.

Oh brother... Why so antagonistic?

From my reading Brent is not challenging the laws of physics, just the simple fact that this one law stand alone is not the sole and only reason that results in an engine reving faster.

Therefore to conclude "that" as a general statement of fact would be erroneous, as you'd be omitting other influencing factors.

At least that's how I've read it.
Clearly Ive read it differently to you.
