The main purpose of the flywheel is to help smooth out an engine at idle and conserve energy. I use a 16lb lightened 228mm flywheel and noticed a slight difference between shifts compared to original with no noticible idle problems. Also, lift off the gas while cruising, the car will not keep on rolling as long. If you go up and down rolling hills, you definitely have to put more gas into it when cruising. The engine does seem to rev up a little easier from rest. Machining a steel flywheel(13-16lbs) is about $150. An aluminum one (8lbs) is about $500. Steel flywheels can be brought down to 8lbs with some pretty fancy machine work. All tradeoffs with compromises.
