Since you're a drag racer, I can see why you would consider Nitrous FI; it's not "all motor". While excluded from "all motor", it's still not forcing a positive pressure into the manifold, the engine is still aspirating on its own.

OK I see where your coming from and its half correct and half wrong, I will explain my view on the other half I feel is wrong.
Nitrous is the F/I during the molecular level its at when it enters the cylinder in a stable form. When it vaporizes, nitrous oxide provides a significant
cooling effect on the intake air. When you reduce the intake air temperature, you increase the air's density, and this provides even more oxygen inside the cylinder. creating a F/I condition.
