All the drag race guys that I have talked to on this subject swear by the aluminum flywheel. It should be noted that they are all racing mustangs that weigh around 3300. I am positive that the weight of the car plays a factor. It might not work as well in a heavy old Torino or Charger. (or something similiar) Rearend gearing and transmission first gear ratio might have something to do with it as well.
