Assuming you are running good fuel, when spraying nitrous retarding the timing isn't costing you horsepower. It's all about "timing" of course. Nitrous causes a quick and violent burn. Since the burn is quicker you must retard the timing to have the peak cylinder pressure occur at the correct time in relation to the position of the piston. So retarding the timing actually makes more power and (of course) it saves the motor from distruction.
