John was extremely clear. Nothing he says disputes anything I have said. You disputed a Acceleration gain. But John clearly covered that. The question he didnt answer was RPM. Well back in 2001 we didnt have the Data Loggers that we do today to measure distance, RPM, speed, Time etc. My Data Logger says I gained 257 RPM's when I went to a Billet 4.10 Lb Flywheel vs a 7.2 lb Flywheel in 800 ft. When I ran it out to 1000+ I gained almost 300 RPMs.
I dont need to explain any more to you Chris. No matter what I say you will dispute it. Like you said You dont even like me. So that in itself explains how you will respond no matter what.

I never disputes acceleration. You said 200 to 300 rpm gain. I disputes that. Are u reading the same thing I am? John says no gain except acceleration. You say gain in top rpm.

Wait, now your saying 200 to 300 rpm on 800' . Uiu originally said 200-300 rpm on the top end. That is completely different and possible. All along I've been saying max attainable rpm, no time or distance restrictions. You've completely changed your position.

So no matter how you want to word it, putting on a lighter flywheel will always be an improvement. Irrelevant of what amp flywheel you have.
Do they make a lightweight 40 amp aluminum flywheel that weighs the same as or close to a 16 amp aluminum flywheel?
Then is the 9 amp even lighter, I never seen a 9 amp in real life.
So trying to get over technical here, Then if a 40 amp is in full amp mode, that would affect the RPM's more than a 16 amp in full amp mode, right? Therefore slowing your rpms just a tidge. The more amps drawn is more strain/resistance at the flywheel?
In general, do you need a matching Stator for the flywheel amperage?If I don't ask any questions, I'll never learn anything.

So same question, will it spin 200less with the heavy wheel because that's all its got for that weight going wide open stretched out?

Take it to the extreme like the example I gave with the 5hp or the infinite condition.You might not get to full rpm because the rate of change is too slow. Shouldn't play with these weights but ?

In my case with a sterndrive Bravo, my flywheel is appx 30 pounds..and I could get a 10 pound flywheel, but with a carb (as opposed to fuel injection), it's too much risk for dock adventures....so I'll stick to the heavier flywheel and look at lowering the other rotating mass (pistons, crank, etc)

Sorry classic, we went off on a tangent. Maybe you're right about the clown show at the dock or just set idle a bit higher?
