What's the difference in weight between a TBM flywheel and a total loss flywheel? Why can't a charging flywheel be made closer to the total loss weight.? I know the magnet weight/mass, but why cant the actual flywheel be made out of lighter material. What is the tipping point for a flywheel being too light?

I posted up the weights of my TBM and a RAD Flywheel awhile back and I think someone posted up the weight of a total loss flywheel in the same thread. They are getting pretty close in actual weight but the real difference is in the location of rotating mass in regards to center and the opposing force of the magnet(s) and field.

Here's the thread with all the discussion that goes with it.

i'm not going back...it's just been one of those questions in the back of my mind. I've read multiple threads that discussed this topic, but I never really had a firm answer as to why you can't have a charging wheel the same weight as a total loss wheel. 4 oz. seems to be negligible with regards to rotating mass, but if it's 4oz located at the outer edge then I guess it would make a diff in the ability of engine to "spool up."
For those of you who use TBM's with enhancers and have run TL's before can you tell much of a difference? The charging feature is like gold to me...I haaaate to mess with charging my battery. That said you can buy a complete used TL for the same price as a single TBM wheel (used)??? TBM must think that feature's like gold too...... ................I just read this thread (http://x-h2o.com/showthread.php?t=74346). No need to answer my last question. I'm a TL guy.

Part of the reason the flywheel can only be so light is because the rotational forces are basically trying to rip the flywheel apart and the more weight the greater the force. This is one reason why you see more charging flywheel crack than the total loss ones. Obviously, the lighter you go the less forces you have but at the same time you still need enough beef to crank the engine and enough to weight that you don't plow into the handlepole when you let off the gas.
The metal required to turn the engine over isn't going to be massive so that really puts the weight requirement more on comfort of the rider when letting off the throttle. I believe the total loss systems were originally designed for racing so I'd bet we could shave some weight off our flywheels since we don't see the continuous high rpm runs that racers do However, if I'm wrong, the flywheel could grenade your cases too so it's one of those things...reward vs consequence.

Our new motor is soooooo cutting edge that it does not require a flywheel...
Until you decide to run it. We can't find a flywheel to hold up to our target compression #'s.
