General information about flywheels:
It is a widespread misconception that a larger/heavier flywheel is used to give the engine more torque, and that torque will decrease with a lighter flywheel. This is NOT the case. Heavy flywheels are used purely to make it easier to engage the clutch so that even a beginner can drive off without stalling—nothing more, nothing less. Once the car is rolling, a heavy flywheel becomes completely unnecessary. By that point, the drivetrain and the car’s weight already have so much momentum that a heavy flywheel doesn’t add much to it. Extra weight, especially on the crankshaft, actually slows down the car’s acceleration. So if you don’t plan on driving like a grandma, a light flywheel offers nothing but advantages.
In practice, engine response is much better, and the car accelerates a lot faster!
