The motor winding up faster is not just some interesting anecdotal side effect. If the engine winds up faster when running full throttle in gear as it will with an aluminum flywheel, that means the car is accellerating faster. It is a waste of hp trying to spin up a 30lb disc from 1,000 rpm to 6,500 rpm as fast as possible. It takes a lot of HP that could be going to the rear wheels. It is a parasitic loss. Think of all the time, money, and effort spent in building up our engines for maximum power. The $100 differnece to get an aluminum flywheel over steel of cast iron is a small price to pay for 1/2 second off your 1/4 mile times as indicated in one of the posts above, or for blowing off the competition on the street. It is free hp that is no longer being wasted trying to rotate a 30lb mass.
