He means a box with a final drive. Mfactory claim that the 4.64 final drive delivers an approximate 9% increase in effective torque ie if 2 identical cars (with the only difference being that one has the 4.64 FD installed) lined up against each other, the non 4.64 FD would need 9% more torque to accelerate at the same rate as the other car.MaccaIRL wrote:So a lightened flywheel (fidanza) and ATR box would be a better purchase than cams and map?
