A buddy and I are going back and forth on this:

Is nitrous considered "Forced Induction"?

 

No. Absolutley not.

 

Nope... We get out own section. :-)

 

So if it's not forced induction and it's not naturally aspirated, then what the heck is it?

 

efficient n/a...only 1 baris going into the motor...

 

Only one bar is going into the motor? What do you mean?

 

You can't call it Forced Induction because your not forcing air into the motor. Which is where the term comes from. You are just injecting nitrous into the intake tract. You could still call it Naturally Aspirated if you wanted to as the motor is still breathing the same way. All your doing with Nitrous is increasing the oxygen content of the air that's entering the motor.
Edit: you also lower your IAT as well.

 

some people call it cheating..... LOL

 

lol It's only cheating if you lie about it.

 

Well, thats what the losers call it. lol

 

definately not forced induction

its a "power adder"

 

A bar is one unit of atmosphereic pressure (14.7 psi). A bar is basically the metric way of measuring pressure.

As stated above: 1 Bar = 14.7 PSI

Nitrous is in it's own catagory of engine set-ups IMO.
NA / Forced Induction / Nitrous

 

Maybe you could call it UN-N/a?

 

Spray splits into oxygen and nitrogen once heated into a gas from liquid. So the injection of the spray into a motor means that more oxygen is available during combustion. Now, you have more oxygen, you also inject more fuel, thus more power. During this, it vaporizes, spray gives a "cooling" effect on the intake air. When you reduce the intake air temperature, you increase the air's density, providing even more oxygen inside the cylinder.


Simple terms: It's a poweradder as mentioned above, easy tune, and, well, just a blast when that 300shot hits ya like a freight train (and you watch the reaction of your passenger)

 

Some claim that when I talk about the dry nitrous it's forced, so not sure...

Oh! I wasn't sure what he was talking about. I know about "bars" or barametric pressures.

Well, I guess I was wrong. I thought it was forced induction because oxygen is being "forced" into the motor. It's just in another form until it's heated.

 

Of course we get our own section but I consider it Chemical Forced Induction. Nitrous is 2 parts nitrogen and 1 part oxygen. Its a whole different mechanical concept than a blower/turbo but in essence, they are both moving air. Obviously this is just my opinion

This is actually a pretty good debate.

 

While nitrous, turbo's & superchargers are both considered "Power Adders". Nitrous is not considered "Forced Induction" like blowers & turbo's are.

 

Oxygen is not being forced into the engine with a Nitrous setup. A naturally aspirated engine sucks in air which we all know is Nitrogen, Oxygen, Argon, Carbon Dioxide, Water Vapor and trace amounts of other chemicals. When Nitrous is applied it oxidizes the air and cools it at the same time so the engine sucks in oxygen enriched, cooled air. So, as you can see, air is not being forced, it's just being changed.

 

Using N2O, you are injecting a large amount of O2 into the intake once it is heated to split. You are increasing the O2% in the air the motor is using. It is not pressurizing the intake however the result is a similar reaction. In Trubo and Supercharged engines the extra oxidizer is in the form of the extra air "forced" into the combustion chamber. In N2O the extra oxidizer is in the form of a higher O2% in the air inside the combustion chamber. Two completely different ways to increase the amount of oxidizer available.
