aluminum flywheel???

A flywheel is deisgned to help carry the crankshaft to the next stroke. Reducing its weight just makes it harder to go to the next cycle.

I don't know if it would help our cars that much. I think it's more of an import thing (small displacement, light pistons and stuff, easier to carry to the next position in the firing order).

just the opposit. lighter engines need heavier flywheels (reletively of course). the heavier engines, due to their mass, inherently have a greater inertial potential. which means it takes more initial energy to get them going and to slow them down. our engines should have no problem at all carrying to the next stroke even without a flywheel. they'll just be really choppy. by offering initial resistance (both to rotate and stop) the flywheel "smoothes out" the engine's torque delivery. with a lighter flywheel the engine becomes more responsive and with less rotating mass some HP is freed up too. the only real reason we have iron flywheels on our cars (even LS1s have them) is because they are cheap to produce en mass.
