NA means a motor making power with NO power adders like a Turbo, Supercharger, or Nitrous.
F/I is a motor making power with Turbo or Super Charger
Bottle Feed is Nitrous lol

Hey infamous,
Great question, and this one is pretty simple.
Forced induction essentially means that something is forcing more air/power out of the motor. Therefore anything like a Supercharger, Turbo, or Nitrous(in a way) would be considered F/I while N/A means the motor is doing it naturally without the use of a power adder.
Hope this helps and let me know if you have any questions!

Nitrous is not technically forced induction. The difference between naturally aspirated and forced induction is the means by which the air is drawn into the combustion chamber.
Induction literally means the inspiration (drawing in) of air into the combustion chamber. Aspiration means drawing air into the combustion chamber by suction. Back in the day it used to be the inspiration/aspiration of a fuel/air mix, but now with direct injection it's just air. The two words, inspiration and aspiration are essentially interchangeable.
The operative words are "forced" and "natural." Forced induction means the inspiration is aided with an outside source such as a supercharger or turbocharger. They compress the air and literally "force" more air into the combustion chamber than the engine is capable of drawing in naturally. Natural Aspiration means the aspiration is performed using only the suction caused by the movement of the piston in the cylinders, without the assistance of an outside force.
Nitrous is an artificial means of increasing the energy potential of the fuel/air mixture. It does not change the way the air is drawn into the engine, therefore, it technically is not Forced Induction. In common terms, Nitrous is typically just considered a "power adder". To make matters confusing, people also consider turbochargers and superchargers power adders since they also increase the energy potential of the air/fuel mix, just in a different way than Nitrous or Methanol. So, an engine can still be naturally aspirated even if it has a power adder (nitrous or methanol), but once you slap a turbocharger or supercharger on it, you are in the realm of forced induction.

Not ragging on you but how does an auto enthusiast not know this? If you were really curious why didn't you just google it....

Looks like Dr. Sheldon Cooper escaped from the set of the Big Bang Theory and accidentally found a car forum on the internet.

N/A - ambient pressure at the engine inlet
FI - higher than ambient pressure at the inlet compressed by a compressor either driven by a turbine using exhaust gases (turbo) or off the engine (supercharger).

His post count is low and he is probably completely new to the "car enthusiast" game. Relax.
Also, not everyone's Google Wushu is strong. He came to a car forum to ask a simple, but legitimate question that several people quickly answered. At least it wasn't another question like "Which sounds better? The Corsa Extreme or the Borla ATAK, derp?"
