Flywheels both smooth out engine roughness and "store" rotational energy
to help a motor to keep turning and to impart that stored energy to the
rear wheels when you release the clutch.
Remember inertial physics about bodies in motion, etc? That's your
flywheel. It's also the reason that many relatively low powered cars tend
(stock) to have heavier flywheels. The extra weight translates in to
greater inertia which wants to keep noving/rotating when you drop the
clutch.
The extra weight, however, takes longer to either speed up or slow down,
too, which is why engines with lighter flywheels rev quicker. There is,
however, no free lunch. If a lighter flywheel lets a motor rev up quicker
the opposite, that the same motor will lose revs quicker, is also true.
The weight (equaling stored energy) of the flywheel more or less
determines how long you have to get a car moving (from a standstill)
before the increased load/effort on the motor causes it to stall or the
car starts moving. A heavier flywheel tends to keep the motor running
smoother and longer in this transition, making the process of getting the
car moving smoother.
So a very light flywheel may not be what everyone wants or needs,
particularly in SF.
