Reply to "Flywheel Mass vs. Acceleration"

my $0.02, as a machine dynamics problem and not as an experanced automotive expert.

the benifits of less flyweight mass is the reduction in inertia so power can be applied to acceleration. the 20# less at the motor is where the least amount of excessive weight (inertia) has the most effect. the increase for acceleration in increased by the gear rations so the 20# reduction would be like a #200 reduction at the drive wheels (in 1st gear)

the negative with a light flywheel is in the transfer of engine power into kinetic energy and its storage. a light flywheel will require a very experanice driver to be able to release the clutch and apply throttle to transfer the little KE of the crank/pistons, where a heavy flywheel will deliver the stored KE as the cluth is released.

so if the car was manufactured with a light flywheel, the car would not be drivable to the public and clutches would become a warrenty nightmare as over throttle slipping would be required

the ability for the rpms to spin up quicker would also apply when the cluth is disengaged and they would fall off, thus requiring experance with the throttle to match rpms
