Q:
A youngster at work showed me an airflow controller he had just bought. I asked him if he had any upgraded internals to the engine. He said no, So I asked him usually people by the controller if they do. He then tells me that he has a forced induction system on his car. I said ok, you added a Turbo or Supercharger to your engine. He said no, I have nitrous.
Now has the meaning of forced induction changed?. Is nitrous considered by the younger generation, forced induction?. Am I out of the loop?.
Help. lol

nitrous does put more oxygen in the combustion chamber, but i doubt ricers think in those terms, they just think NOZZZ = MASSAVE BURNOUTS. i still wouldnt concider nitrous to be forced induction.

Nitrous makes an "all motor car" no longer "all motor" so they get confused and think it's forced inducted...lol

A:
"forced induction" means forced.
changing the mixture of incomming gasses does not qualify.
A:
Some people think "forced induction" and "power adder" are interchangeable.

A:
I think you can make an argument that spraying a high pressure stream of Nitrous to add oxygen is kinda the same as a compressor
A:
same as a compressor? nope.
A:
My own definitions
Forced Induction: The process of adding additional air to an engine through a means other than the natural process of the pistons sucking it in
Naturally Aspiration: An engine that only obtains air through the natural process of pistons sucking it in
Nitrous Oxide adds additional Oxider to the intake charge, oxygen. It changes the mixture, it doesn't add additional air to the process. If you're saying that this can be considered forced induction then you could also say richening the mixture would be forced indution, although all you're doing is adding more fuel from a high pressure stream.

A:
Forced induction = pushing more than 1 bar of pressure into the engine.
Nitrous will not significantly raise the air pressure, so NO, it is not forced induction. It's really just an oxygen enhancer.
A:
Depends on your definition. In some ways it does have what many of us consider to be forced induction properties. In other ways, like 'forcing' air into the combustion chamber, it is not. If used during racing, I'd consider it closer to FI than n/a. Either way, your are getting more air into your combustion chamber than possible otherwise.

"Nitrous will not significantly raise the air pressure"
NO2 is forced into the cylinders at super high pressure. NOS falls into the category of forced induction. IMO

"Forced induction = pushing more than 1 bar of pressure into the engine."
z32, you do know that one bar is approximately 14.5 lbs of pressure, so you're telling me if you have a turbo or supercharger pushing 14.4lbs of boost or less isn't forced induction?
dexter,
You were probably a lot more courteous to the teen than I would have been. I would have given him a lecture similar to MeAndMyZs' explanation, then told him he doesn't know what he's talking about, OR his friends...see my sig at the bottom.
But I have heard that Nitrous is the "Poor man's forced induction" Hahaha.
God must love stupid people, he made SOOOOO many of them!
A:
mike, you do know that boost is measured above 14.5psi?
that zero on the boost gauge IS 14.5, right?
A:
Hey Mike, I could have jumped on him but he didn't know, so no reason to do that. If he had bet me or said I don't know what I am talking about, I might have used my Size 12's and stomped on him.
Besides he works in the parts dept at the dealership we work in. No parts help if I jumped on him. :o)

A:
maybe he was thinkin power adder
A:
What tkr said, he's right on.
The atmosphere produces 1 bar naturally into the engine (if the engine is a vaccuum), which is why engines work at all. A turbo producing 5 psi positive pressure is forcing 1 bar + 1/3 bar.
A:

Er, no it isn't. The NO2 is released into the thottle body, which drops the pressure to almost whatever the intake is. Otherwise the nitrous would blow out of the airbox instead of the engine.
A:
NO2 can be "forced" into the engine via WET or DRY or PORT

An Overview Of Wet, Dry And Direct Port Systems
These are three basic types of nitrous systems: dry, wet, and direct port. The most misunderstood is the "dry" type of system. A "dry" nitrous system simply means that the fuel required to make additional power with nitrous will be introduced through the fuel injectors (remember, fuel makes power, nitrous simply lets you burn more of it). This keeps the upper intake dry of fuel. We accomplish this by two methods. First, is to increase the pressure to the injectors by applying nitrous pressure from the solenoid assembly when the system is activated. This causes an increase in fuel flow just like turning up the pressure on your garden hose from 1/2 to full. The second way we can add the required fuel is to increase the time the fuel injector stays on. This is accomplished by changing what the computer sees, basically tricking the computer into adding the required fuel. In either case, once the fuel has been added the nitrous can be introduced to burn the supplemental fuel and generate additional power.
The second type of nitrous kit is the "wet" style of kit. These kits include carburetor plate systems and add nitrous and fuel at the same time and place (normally 3-4" ahead of the throttle body for fuel injected applications or just under the carb as with plate systems). This type of system will make the upper intake wet with fuel. These systems are best used with intakes designed for wet flow and turbo/supercharged applications. The reason for this is the fact that fuel flows differently than air or nitrous. This difference in flow characteristics can lead to distribution problems and, in some cases, intake backfires. Intakes designed for wet flow (such as with carburetors) cause much less separation of the nitrous/air, and fuel. Because modern fuel injection intakes are designed to flow air only, they have tighter turns and a more compact design as a result. Thus, they generally do not make good candidates for wet flow nitrous systems.
The last type of system is the direct port system. Just as it's name implies, it introduces the nitrous and fuel directly into each intake port on an engine. These systems will normally add the nitrous and fuel together through a nozzle known as a Fogger nozzle. The fogger nozzle mixes and meters the nitrous and fuel delivered to each cylinder. This is the most powerful and one of the most accurate type of systems. This is due to the placement of the nozzle in each runner, as well as the ability to use more and higher capacity solenoid valves. A direct port system will have a distribution block and solenoid assembly which delivers the nitrous and fuel to the nozzles by way of connecting tubes. Because each cylinder has a specific nozzle and jetting (both nitrous and fuel), it is possible to control the nitrous/fuel ratio for one cylinder without changing that of the other cylinders. These systems are also one of the more complicated systems when installation is considered, as the intake must be drilled, tapped, and the "plumbing" made to clear any existing obstructions. Because of this and the high output of these systems, they are most often used on racing vehicles built for the strain of such high horsepower levels.

A:
NO2 = nitrogen dioxide != nitrous oxide (N2O)
A:
It's simple -- nitrous in any form (wet, dry, or port) is NOT forced induction. All the air in the engine is still sucked in by vacuum. Forced induction is FORCING AIR INTO THE ENGINE! Normally Aspirated is the converse of Forced Induction, and it means the engine aspirates the air into cylinders via normal vacuum means.
What the hey, people.

Tell them the best way to plumb it forced indction style, he would need to drill a hole next to the spark plug and screw the nozzle into it. LOL I hate ricers!
I had a argument with one a while back at a local hang out, while some high school kid said I would have more power if I just did a intake and exhaust to my isuzu truck instead of v8 swap that was in it. LOL He freaking went on about using a 1.5L motor is better cause since its smaller it can build larger compression and get more HP. He finally stoped talking to me when I suggested a briggs and straton 1.5HP motor for his honda with a intake and exhaust. LOL
