I'll ask my Master Tech buddy again so that we will have the technicalities that make all this stuff happen.
My first Post on THE DASH FORUM.
A lighter flywheel does result in faster acceleration, it also results in faster decceleration.
A lighter flywheel does not decrease drivetrain loss.
A lighter flywheel has less stored inertia, this means higher revs to accomplish the same launch or the same motion to move the car. Now because of the less weight it also takes it less time to slow down. Example is if you have a spinning object with a weight of 20 pounds and another with a weight of 10 pounds it will take more force to stop the heavy object in the same amount of time as the lighter object.
A lighter flywheel causes a car to use more fuel. It is very minimum but because of less stores inertia you have to give a car more gas to maintain the same speed.
A lighter flywheel does not make more HP.
A lighter flywheel on a dyno shows to make more HP because a calculation of the dyno is time, so if the lighter flywheel makes the car rev up faster this is then transalted as a factor of HP.
Lets look at it like this lets say the average human can generate 2 hp, then you jump on a bike and pedal now if you put more weight on the pedals you will not be able to go as fast because if you generate the same amount of power you will move the heavier object slower.
