I've always read that you loose about 15 to 20% of the HP through the drive train, but lately have questioned that percent of loss. RBT transmissions, who make the ZF trans axle for GT40s and Panteras, say there is only a 16 1/2 HP loss through a ZF. I would be more inclined to say that there is a 20/25 HP loss through the drive train, and not the 20% that some folks claim.
