I think there are numbers someone posted one time to bear out the flywheel part.
Advantages of lightweight flywheel.
There is no downside to the light flywheel.
Though a lightweight flywheel does not create additional horsepower it does allow the engine to more rapidly transfer its power to the drive train.
A lightweight flywheel allows an engine to have quicker throttle response due to its reduced mass.
I noticed the flywheel difference the very first upshift i made out of the garage.
The relevant basic physics relationships are which is the rotational analog to and.
Typical benefits of a lightweight flywheel.
The mass of a regular flywheel will be more thermally stable than would a lightweight one.
This provides for more longevity of the flywheel.
A lightened flywheel produces more responsive shifting and engine rpms as well as generally improved acceleration throughout the gears.
As for benefits i consider the flywheel and gears the best mods for sotp on a stock car.
Without the weight of the flywheel pedaling is more jerky and is more of an up and down motion which can add pressure on to your joints and can make you more susceptible to injury.
With a light flywheel you are constantly adjusting your pedalling speed.
Lightened flywheels reduce drivability under most circumstances.
The lightweight one will have more problems with overheating and losing grip after such events.
At a given idle speed a lightweight lower moment flywheel will have less stored energy than the stock one so you have to adjust your clutch engagement and throttle input accordingly.
There are significant benefits of an aluminum flywheel.
The flywheel also provides a more fluid cycling motion.
The advantages of a light weight flywheel are the same as reducing the weight of any part of your drive train you are going to get a quicker revving engine.
That is because the rotating mass is drastically reduced.
