Dude first of all I don't know why you're posting stuff about turbocharging. That has nothing to do with nitrous. Second of all your answers.com site says:

"Forced induction is a term used to describe internal combustion engines that are not naturally aspirated. Instead, a gas compressor is added to the air intake, thereby increasing the quantity of oxygen available for combustion."

IS an NO2 system not using compressed gas? Yea, just wondering on how that doesn't fit...

Also Urban dictionary I treat that as less credit worthy then wikipedia. You're right Nitrous isn't boost but it is forced induction. Something does not have to be reffered to as boost to be considered forced induction. I'm not gonna have a link war with you cause I know I'm correct and If Nitrous isn't N/A and its not FI then what the hell is it? Are you just gonna create your own little category for it to justify your reasoning? Well congrats I guess you made a new discovery.

Good day.

i linked to that answers site to because it made a point, that a forced induction motor has a gas compressor on it. show me a nitrous system, then show me the gas compressor. what? there isn't one? then how exactly is the induction process forced?

i'm not trying to justify my reasoning, plenty of people agree with me. if it is too hard for you to comprehend anything more complicated than "if it isn't NA then it's FI", then fine, refer to nitrous as FI.

Packman.... turbos compress air at about 7-20psi normally, nitrous bottles compress the n2o at 900-1100 psi, now how is that not a gas compressor exactly?

sorry, but a compressed gas is not a gas compressor. if you can't grasp that concept, then i'm not sure why we're even discussing this. as soon the nitrous is out of the bottle it is no longer compressed, it is not adding 900-1100psi to your intake.

Look, the bottom line is if the air/fuel mix is sucked into the engine, it is not forced induction. unless the air/fuel mix is forced into the engine, it isn't forced induction (hence the term forced). If you want to define the word differently, then so be it. Otherwise, this is a good FAQ for people who don't know what nitrous is, i would just hate for them to think it was FI when it clearly isn't. sorry to hijack the thread, if a mod wants to clean it up since it is a sticky, go for it.

oddly, i think both sides of the debate are off-base. nitrous is an oxidizer, it's not N/A or FI. nitrous works exactly like adding some other oxidizer to your gas. (micheal waltrip getting caught with an oxidizer in his gas at daytona comes to mind...) IOW it's neither N/A of FI, it's it's own deal.

if i were to debate what category NO2 fits in, i'd come at it from the fuel side, rather than the air.

maybe i'm nuts, but that's how i've always understood how it works...

^ I am willing to agree that it would be better suited as its own category as an oxidizer but I think that if you have to pick between f/i and n/a then it is f/i because n/a means that it happens naturally and adding nitrous is not something an engine does buy itself.

Packman, I definitely do not want this "cleaned up" although we disagree, this is a forum and we all need to add our own opinions because if only one person gets their say in it then people reading it might be mislead... they need to be able to form their own opinion. You should never take something you hear from one person as a fact.

Uranium, the only thing I think that you cannot debate is that if nitrous is a fuel or air. It is oxygen, not fuel. It helps you burn more fuel just like the air that is already there does. Think about it, it is n2o, meaning 2 nitrogen molecules and 1 oxygen molecule. If nitrous is fuel then why do you add fuel in with it (wet setups) or trick the engine into using the injectors to add the extra fuel (dry). One of the reasons we don't just use pure oxygen instead of nitrous is that the nitrogen also cools down the engine and pure oxygen would not do that.

that's because i mis-read the differences between wet and dry systems when i went through this thread earlier, i was under the impression that wet systems were basically special fuel injectors...plus, i'll admit i'm new to nitrous systems.

but i am an engineering student, so believe me, i know it's not a form of fuel, that it is an oxidizer, and that i know what an ozidizer does.

and if i had to put it into either category, i would say it's F/I. it's not really F/I, but it certainly isn't N/A.

Whenever you add nitrous into an engine, just like normal air, you need fuel to go with it to make any more power. Wet and dry systems are just two different ways of getting the fuel you need into the engine. Dry systems only inject nitrous and they trick the fuel injectors into adding the extra fuel. Wet systems add the fuel through the same nozzle as the nitrous atomizing the fuel and nitrous together before it gets into the combustion chamber.

First of all a Turbocharger/supercharger doesn't force air into an engine. If you were to try to "force" air into an engine you would end up flith valves floating and horrors of this type. All a turbo/SC does is compress the air to make more air available for the engine to suck into the vacuum that is created from the exhaust gases being evacuated after the compression cycle. Naturally the more air that is available the greater quantity that will be sucked in. It does not physically force the air into the engine whatsoever.

Think of it like this. Get a straw, stick it in a ziploc bag and seal it around the straw and suck in. You can only suck in so much right? Now blow the ziploc bag up and suck in, you would be able to suck in more air right? All F/I does is "blow up your bag" If it were to force the air in think of it like someone else blowing in the other end of the straw while you were sucking, you'd end up coughing and all that goos stuff cause you wouldnt be able to handle the extra air. Thats what would happen if you "forced" air into an engine.

Secondly when a turbocharger compresses air does it not increase the oxygen density of the available air to the engine? To go along with this does adding N2O to the intake stream not increase the amount of oxygen in the plenum therefore making it dense just like the Turbo?
