I will still say that it is not F/I as I set forth definitions based on websters dictionary. So until someone can dispute it with facts as I have done, then maybe I will change my mind.

There were only a few who presented a real argumeent based on facts against F/I. All the others just say I think bla bla bla, N2O forces air in because I said so...waahh

NOS is not F/I except by class rules only, done.

i think nitrous is a form of FI as you are Forcing air into the engine... but i dont think its so much a form of FI as much as Superchargers or Definitly turbos.

so in a sense it is but it isnt thats just me

You just said " I am an indecisive person that wants to please both sides"

There is not such thing as "a form" of FI. It either is or it isnt FI

And it does not force anything into the combustion chambers.



So on this token, is water/alky/meth injection FI?

According to some yes because it cools the charge air making it more dense which translates into more oxy. So just like N2O you need to dump more fuel when your meth plumes to keep afr's where they should be because of the increase in air density.

N2O is not FI and niether is water/alky/meth

well you are very true, i did please both sides.

i dont think its a true form of forced induction.

but i do think its a form of ''induction'' as you are putting another form of cooled charges of air into the motor thus increasing the ammount of power.

IMO other than increasing the ammounts of power a Motor makes, i think that Nitrous is best used on Actual forced induction applications, NOT as a form of induction (or increased air consumption) but as a form of cooling for the intercooler or the air intake charge.

I wonder how NOS, Express, and all those nitrous companies consider nitrous?

they probably consider it a form of Forced Induction.

Power adder?

That seems to be the best descritption since we are all having trouble defining it as other wise.

It should be classified as some sort of chemical something in the same way meth inj is IMO.

I know N2O works two fold, cools air charge and adds O2, but so does meth, just not on the same scale of adding O2 as N2O. But it does increase O2 as explained previously.

they probably consider it a form of Forced Induction.


I would dare to say, at least IMO, there are 3 types of combustion engine setups.

All motor, F/I and N/A.

I know, N/A and all motor seem the same. But IMO when N2O is introduced, it is still N/A, but def not all motor.

On another level, what if the amount of oxy in cylinder from the nos plume is so great that you could equate it to 14psi (which means the engine sees anough air to count as 2 atmospheres) and the cylinder pressures confirm as such, then maybe it is forced induction.

I almost convinced myself it is F/I

But then it just doesn't fit the definition of forcing(make someone or something perform an action of any sort against their or its will) the induction (induct= to bring someone or something in) of air into the comb chamber

Lets call it oxygen induction.

here is what you do go back up to the guy and aks him to see his no2 bottle he will look confused then say noss like in fast and furrious he will then understand and open his flip flop trunk with the huge wing ,when he shows you ask him to close the valve when he leans over the to close it repeadly bash his head on the bottle while screaming you are a f%^&*ng retard untill he stops moving then close the trunk burn the car and you will have done us all a great deed by taking one more retard out of this retard infested world . in no way shape or form is nitrous forced induction
there are 2 count em 2 forms of forced induction supercharged or turbocharged.forced induction is just as it reads forcing air in to the motor.
nitrous does not do that ,at all ,not one little bit 0 ,zip,zilch, nada . In racing terms there are "power adders" ie turbo , supercharger , nitrous depending on the class you run you may be allowed one or more of these . This is the only way that the 3 are refered to by the same termonology .

i totally agree with the whole its not forcing something, or doing against its will.

I do my best

^^^ I agree with this as far as classifying n2o.
As for why I think that nitrous is not a form of forced induction, like many others have already stated nitrous does not force anything into the engine that wouldn't already be there in an "all motor engine". Air is still drawn into the engine, and on that note, wouldn't the amount of atmospheric air being drawn in decrease due to the fact that the nitrous displaces it in the cylinder? So in essence nitrous is actually creating the reverse of "force", it would be preventing as much atmospheric air from entering the cylinder. Correct? Just my 2 cents.

Here I have to say what about the nitrous?!? The nitrous is under pressure in the bottle so it is most definately being forced into the engine (it does not exist under pressure in its natural state). And what is nitrous? Nitrogen and oxygen. What is air? Mostly nitrogen and oxygen. So what is so different about forcing nitrous (remember it is under pressure) and forcing air?

That would be true except for the fact that the expansion of nitrous from a liquid (in the line) to a gas (in the intake) cools the incoming air making it more dense thus allowing more air to enter the cylinder.

If the engine wasn't drawing vaccum the nitrous could just as easily exit through the air cleaner. It's only being forced as far as the nozzle.

I dont know, the way I see it is the nitrous IS going into the cylinder and it DOES pack in more nitrogen/oxygen than would normally be present in a N/A engine. I also see the flipside of the argument that the intake manifold isnt seeing positive pressure.

To me it just comes down to more "air" (which is basically what nitrous is, just compressed into a liquid) being put into the cylinder than it could normally hold. Thats why I think it is forced induction.

You guys are a bunch of ricers that moved over from honduh, because nissan is the new IT

for it to be forced induction it would need to raise manifold pressure above atmospheric pressure.

Which will not happen since this is not F&F. Your manifold wont give off a warning alram and your floor board will be fine.

The only time the manifold is subject to pressure is when the nitrous eplodes in the IM blowing the IM to pieces like I have seen on mustangs on u-tube

That would be true except for the fact that the expansion of nitrous from a liquid (in the line) to a gas (in the intake) cools the incoming air making it more dense thus allowing more air to enter the cylinder.
Good call. I didn't think of that.
