The stock flywheel is approx 28 pounds and not good for performance. Aluminum is faster, by as much as a half second in extreme cases. It's the same in concept to bolting on a set of weld draglight rims or an aluminum driveshaft, less rotating weight, more acceleration. Aluminum flywheels are so effective at boosting acceleration that they are often banned from use in most road racing classes because they provide an unfair advantage over those people who can't afford them. As for the loss in torque, if your engine makes 330 ft-lbs of torque an aluminum flywheel is not going to take that away from you, if anything you will have more going to the rear wheels because it takes less to turn the flywheel. The only thing it does change is LAUNCH TORQUE. Lighter flywheel, less inertia, less of a hit at the tires. Depending on how drive the car off the starting line you could see an inprovement of two tenths on you 60 foot times.
And finally, due to the lighter weight, it will make your engine sound like it has a bigger cam in it than what it actually has.
