Three Wheelin'
A lightened flywheel should reduce momentum. Braking effect is the result of engine/driveline resistance. LWFW should increase braking effect, since it doesn't have to overcome the additional momentum of the heavier flywheel.

The FW (like the whole car) is decelerating when the engine braking effect is felt. As it decelerates, the FW gives up its rotational kinetic energy to the moving vehicle. So it adds to the vehicle's kinetic energy - it keeps the car moving longer. Thus a heavy FW will decrease the braking effect, and a light one will increase the effect.
Think about it this way; If the FW weighed, say 5 tons, then imagine how long it would take the vehicle to coast to a stop when you lift off the throttle. It would take a very long time because the energy of 5 tons of rotating FW would have to be dissipated by engine compression (and aero drag). So a heavy flywheel obviously decreases the braking effect.

i love the chatter. i also love PFC brake pads and the long squeel I can get out of them coming up to a security gate and watching everyone cringe. gt3 is awesome even when just driving around doing errands.
