Oh, and then you have better throttle response too, and maybe quicker 0-speed limit times as well.

EDIT: Oh, and you would probably have less body roll in corners and less stress on engine mounts because a lighter flywheel would have less resistance to change of axis compared to a heavy beast.

I just think lighter FWs make sense on auto trans cars.

please let me know if i an wrong but please don't spout off if you have nothing to back it up.
NO automatics I've ever heard of have flywheels! They're called flex-plates and usually do nothing more than provide a place to attach the torque converter and the starter ring gear.

I never heard of 88s with stick trannies???

As for body roll in corners, flywheels/flex plates/torque converters are oftentimes about the lowest components to the ground there are. You'd likely see a bigger effect on vertical CG by mounting your battery lower in the chassis.
