I for one believe nitrous is not a FI, if you consider Nitrous as a force induction for that reasoning you would have to consider cry02 the same.

Nitrous is pressurized and it's not really even being forced into the cylinders. The cylinders actually suck it in.. like it sucks in the intake. The pressure is there so it is a constant amount of flow and to atomise the fuel and nitrous. When it heats up in the cylinder the nitrogen releases more oxygen and expands in creating more cylinder pressure....

With this said... how do you see it as a forced induction?
