Default Forced induction section.

I was wondering why Nitrous is under the forced induction section? Would that be considered as a "Power adder"? I think the section should be renamed "Forced Induction and Power adders"

I have to agree with Pinky. I know that superchargers and turbochargers are forced induction because they literally FORCE air into the engine. But I don't see how nitrous force air, all nitrous do is essentially cool the A/F charge and add more oxygen thus it would be a power adder. So I voted power adder

Nitrous is considered a type of forced induction just like superchargers and turbos.

I will have to disagree. Forced induction is when compressed air is forced into a engine. See here -

NItrous is compressed air in a way. It is considered a type of forced induction in any type of racing. Anyone with nitrous will be automatically bumped into the forced induction class from the N/A class. It puts more oxygen in the cylinder then the engine can do itself, which is forced induction.

See here:

Quote:
A property of nitrous oxide is that at about 565 degrees F., it breaks down into nitrogen and oxygen. When it is introduced into the intake tract of an internal combustion engine, it is sucked into the combustion chamber and, on the compression stroke, when the charge air temperature reachs 565 deg., a very oxygen-rich mixture results. If we add extra fuel during nitrous oxide injection, the effect is like a super charger or increasing the compression ratio of the engine. Automotive nitrous systems work like the automotive eqivalent of a jet'* "afterburner" and is used for short duration extra bursts of power.

Nitrous oxide has this effect because it has a higher percentage of oxygen content than does the air in the atmosphere. Nitrous has 36% oxygen by weight and the atmosphere has 23%. Additionally, nitrous oxide is 50% more dense than air at the same pressure. Thus, a cubic foot of nitrous oxide contains 2.3 times as much oxygen as a cubic foot of air. Just do a bit of math in your head and you can see if we substitute some nitrous oxide for some of the air going into an engine than add the appropriate amount of additional fuel, the engine is going to put out more power.

Simply stated, nitrous oxide injection is very much like a supercharger or a compression ratio increase in that, during combustion, it can dramatically increase the dynamic cylinder pressure in the engine.

True. It can be considered Forced induction, but really isn't in a big way. I see what you mean by it being a eligible thing for the Forced induction classes.

Nitrous IS in fact Forced Induction, as is nearly any other type of injection such as water, alcohol, or propane, when injected into the intake of an ICE (internal combustion engine).

Any form of INDUCTION other than natrual aspiration is considered forced.

Maybe I'm missing something here.

Please help me understand what is the issue? We don't seem to talk about nitrous that much and whether it is actually forced or not, it may be in this area due to a lack of seperate forum for 1 post a month or less.

I see what you mean now. I was just a little confused at how it was considered that. Thanks.
