In my line of work, understanding cause/effect/forces/(thermo)dynamics/energy/power is what I get paid for. I don't get paid to make guesses, or to assume things I don't fully understand.

Except that physics dictates something else must be going on if he has found extra speed. As its nothing to do with the flywheel being lighter.

The available power is the same EXCEPT for whilst accelerating. During this time (which is not very long time) power would be used to also spin the flywheel. Lets put this in context. Imagine running...

Only applies for acceleration. Try doing the same maths whilst the flywheel has reached max speed and you will see no energy is required.

Hahahah honestly. I really don't know what to say to the posts above. I'm actually laughing out loud at how LITTLE seems to be understood here.

Ok last post on the subject. When its clear not even the foundation of forces or engine dynamics are understood, and a total blindness to even consider them there is nothing I can do to help.

Talking Round and round in circles like a flywheel

Dave, I don't have any time until December now. I'm exceptionally busy during the days at the moment. I actually do want to help. If it teaches you or I a little something then great. :)

Thats why the boating world is so far behind the automotive engine tuning world with regards to engine management etc. I'll offend half of boat mad here probably but I'll use examples of many people...

Only if it affects aerodynamics or frictional losses of the tyres to the road. The extra mass wont make any difference to stop speed other than acceleration.

Here is an interesting thought too...

Because simply put a flywheel is a store of energy. It doesnt add or loose anything that the engine produces it, it just stores it, nothing more nothing less.

A fly wheel is NOT drive train. There are NO losses in a flywheel, other than frictional air losses.

Stick it on an engine dyno. Show me with or without lightened flywheel. If the lightened one shows more power at the prop then original (which isn't possible) then it would make sense. If there is no...

I don't get how reducing the mass of a flywheel can increase top speed???
