As far as I think both NOS and Turbo have same functions. If so, then what is the difference between them? I think NOS is not legal in the US but there are bikes that come with Turbo, so Turbo should be legal and it should be different from NOS.
Also how do NOS and Turbo work?

Kram air in

NOS is legal. Basically Nitrous oxide is a very cold, very oxygen rich gas that causes the explosion inside the cylinder to me much more intense, giving you more power. If you have a solid bottom end, and give it more fuel, you can get some SERIOUS power gains. Turbos are essentially the same, but not cold air, and no refilling your bottle, and lag. Turbos take the exhaust gases and spin a compressor, which pressurizes the air coming into the intake (bad explanation, but exhaust powers the turbo). You can then cool the air, using several types of intercoolers, most commonly air-to-air. Be advised that the better the intercooler (generally), the bigger, and more lag. Lag is waiting for the boost created from the exhaust to actually get to intake, and finally give you more power. There are entire forums dedicated to turbos, so there is much more info to be had, and I'm sure plenty of knowledge from others here, seeing many DSM guys and such.

NOS stands for Nitrous Oxide System. Nitrous Oxide is a gaseous fuel that burns with much heat and gas expansion then normal gasoline causing more power to be able to be produced by the engine.

A Turbo just compresses the air so the engine can put more air and as such more fuel in to produce more power.

And how much an NOS cylinder costs there? And lasts for how much time?

OR even better NOS injected turbo

A sneeky pete NOS system, a Fogger that puts NOS into the airbox and not intake throats can be had for less than $400.00. This gives you a bottle with aprox. 10 shots of NOS. Its Great way to ruin a engine! If you dont know what your doing.
If your trying to go faster, GEARING is the first step. Front and rear sprocet
replacement.

the difference is NOS runs out when the bottle is empty, a turbo will keep going as long as you can hold the throttle open. thats 1

2 NOS is not always the best for an engines longevity, where as a turbo may always have mechanical issues....

so there are good and bad sides to both, NOS is definatly cheaper!

NOS is NOT legal on the street.... If your car or motorcycle is equipped, you can loose it to the impound yard.

Something about transporting flammable materials unsafeley on the roads I think..... look it up in the rule books...

I know someone who lost his ride and his liscense for having/using NOS on the street....

A turbo is basically an air condenser/compressor... a type of forced air induction, feed an engine more air/fuel make more power to put it simply...

that's why F1 cars were making 1000hp with four cylinder engines in 1989.

The fun way would be to dual charge.... set up a supercharger and turbo on your engine.... and have the turbo kick in right as the supercharger peaks..... talk about a power curve.

Boo NOS/Turbo HOORAY Beer!!!!!! THe ghey people called and said they wanted their Topic back.

Djoplin

Uh. NOS is NOT fuel. It's a compressed gas that gives fuel more umph, in not so technical terms. Car won't run on NOS alone. YOu can get a pretty good buzz off the stuff though. BEEN THERE DONE THAT.

DO NOT HUFF NOS--- it is not medical grade and it contains sulfur dioxide (bad stuff)

- NOS is not a flamable gas, it is an oxidizer(read the tank). It is just like air but with more Oxygen (roughly 36% by weight VS air @ 21%). if you JUST add nitro to your intake and no extra fuel you will A) make no more power than normal and B) liquify your pistons in 30 seconds (no I am not joking- you will melt the piston). nitro like any other power added is harsh on your motor and will reduce the span between full rebuilds. If done in a logical way, IE low HP hits used very limitedly, NOS will not kill your bike. THE KEY IS TO KNOW WHAT YOUR DOING. a 50 HP shot on a 600 is just stupid (50% increase in power= good by main bearngs).

What you have to do is when NOS hits you need the bike to go uber rich in the fuel curve- a crap shoot and a pain with carbs but simple with FI and a dual map system. many drag racers use secondary shower injectors in the intake to compensate for the lean condition. -NOTE- a power commander will not help, unless you have it tuned for nitro and you run nitro ALL the time, it is not a dual map system unless you start to heavily modify the base system-
nitro causes the flame front to slow in the cylinder, hense retarding of the timing is required. how much is dependent on the amount of nitro.

turbos work in the same way: more oxygen packed in the chamber+ more fuel= more power+ more maintinance.

- here are some random turbo things people should know... Turbos are way more efficient than superchargers. a ->properly designed and operated<- turbo has no lag (negligable) when used properly in the compressors efficiency area. a good intercooler will have small pressure loss in the core. lag on a turbo is caused by operating the compressor out side of its efficiency curve not by an intercooler. If you want no lag then get a tiny turbo- but the top end will suck. you need to know how to work a turbo motor and know the design specs to get the most of it. IE dont bolt a T-78 to a 600. when a turbo is used properly- get the revs up and dont short shift, they are insane. also if you want to cut lag coming out of corners, dump raw fuel into the turbine intake with an extra injector... instant spool up. A VATN (variable area turbine nozzle) turbo will give you great bottom end and killer top end with no lag compared to a standard turbine. The VATN works by changing the A/R ratio of the compressor through out the RPM's and depending on vac/ boost conditions.

How did they get caught using Nitrous? Unless you purge I would say most cops haven't been trained enough to identify when a car is/has been using nitrous unless he does a vehicle search and finds the bottle hooked up. I say most because I do know some bigger cities have special street racing units that are trained about performance mods. I do believe it is legal to use and transport as long as your vehicle carrys the proper placards for having an Oxidizer on board, and you don't break any laws while using it.

However I could be wrong, the discussion about the legality of it while on public roads has been brought up on other boards I frequent.

96SN95GT

I did not say the engine runs off of just NOS as fuel. I said it is a fuel as in something that burns and causes flame. Perhaps I should have specified more clearly.


And as to an engine won't run on NOS I think that might be wrong. I know an engine is not supposed to and would probably last about 3 seconds if you tried it but I am pretty sure you could run an engine off of Nitrous Oxide. All you need to run the engine (simply put) is an explosion in the cylinders. All you need for this would be a fuel and an oxidizer... Nitrous (fuel) Oxide (oxidizer) should be able to burn all by its lonesome.

The idea is right but I may be wrong.

moparmiller

Nitrous oxide is not required to have an external placard on the vehicle- per DOT regs unless you have a ton of it (literally). But the bottle must have a label that states what it is- DOT gas cylinder regs. An unlabeled bottle gets you a ticket, but I am pretty shure NOS is legal in WA as long as you "dont use it on public roads", but they cant ever prove you used it. even purging the system is not "using it" - unless we somehow fell under CA's CARB -BS-
I dont think there is RCW on nos because 1)we dont have required emissions checks here. and 2) they would have to outlaw every aftermarket part if they outlawed one single one.

And technically it is not a fuel it is an oxidizer- it allows more fuel to ignite because at ~350 degree it breaks apart into N and O molecules. the Oxygen is not a fuel, hydrocarbons are a fuel, oxygen basically gets the bonds breaking and releasing their energy (heat). the nitrogen does nothing- other than slightly slowing the flame rate because it is inn the way.

FatMatt

Nitrous is not a fuel, it is an oxidizer that helps fuel burn more effeciantly. Nitrous by it self will do nothing when it is added to a spark, compressed by an engine or not. No burn, no flame. Nitrous WILL NOT burn all by its lonesome!

I can just see police giving out tickets for using nitrous because of flame coming out of the pipe and they know it is true because they saw The Fast and The Furious so they know thats what happens when you use it!


It does make a difference in the exhaust sound but I don't think you could get a ticket for it.

SRWitt

I hate drag racing cars with nitrous when I don't know about it. Out at SRP last summer I raced like a 95-96 Accord 4 cylinder. I was like 3 car lengths ahead could hear the fart can screaming then it starts screamin even louder and he started to pull on me. Too little too late though, still made me a little nervous seeing I was only at the 1/8th mile mark when he flipped the switch.

moparmiller

hell- the Kennewick cops loved my rods of norco flame thrower set on my 67 dodge... but I can see them trying to have that hold up in court- "but vin diesel said..."

NOS Supports combustion, it has an extra Oxygen molecule.
Turbos create heat, retain heat, can cause the dreeded 'turbo lag', it takes a second for the turbo to spin-up and do its magic. After market turbo's are also hard on an engine that doesnt have systems to support the turbo, I.E. Larger oil cooler, larger radiator, lower compression pistons, bla, bla, bla...

Want more power? Buy a bigger motorcycle. Nothing out runs CC's
Plus, it will LAST.

NOS is an acronym for a BRAND.
Nitrous Oxide Systems.
as was stated already.
although nitrous oxide is commenly referred to as NOS.

there are many companies that offer nitrous systems.

N.O.S. is merely one of them.

bubba_zenetti

wrong. there is no rcw that prevents you from having nitrous on a street vehicle. i should know. i got a 2.5lb bottle hanging off the side of my busa and have been pulled over enough times. one cop tried to find an rcw that he could give me a ticket for it but he couldnt.

as it sits, there is no specific law stating that the use of having a vehicle so equipeed with nitrous is illegal. however, if you get caught driving wrecklessly becuase of its use, you will get whatever ticket is coming to you for that but there is not a damn thing they can do for the nitrous.

bubba_zenetti

i have the biggest bike there is (well the zx14 is out now so........)
i couldnt get a bigger bike. now i got NAWWWWWWWWWWWWWWZ

but for what it is worth. a properly set up nitrous system is the best bang for the buck when it comes to HP gains. for $300 (if you make your own kit) or $800 for a store bought kit, you can have anywhere from an extra 10rwhp to 200rwhp if you and your motor can handle it. with a prgressive controller to ramp the power on instead of a sudden hit, your motor will be ok if you dont get crazy with how big of a shot you can go.

modern turbo systems are great. as soon as i have the time to do so, my bottle will be up for sale and the busa is getting a mitubishi 16g strapped to it.

bubba_zenetti

nitrous is not flammable. nitorus is an oxidizer. it supplies oxygen to fuel. n02 in its own is not flammable.

FYI all NOS brand and Nitrous express kits meet or exceed federal DOT specifications for comressed gas vessles. therefore it is safe to transport a bottle of it. it is no different than having a fire extinguisher in your car. the law states that any compressed gas being trasported must be in a vessle approved by the DOT. the law has specific subsections for hazardous gasses and flammable gasses but since nitrous oxide is neither, it can be trasported with no problems.

bubba_zenetti

oh now he tells me.

liquidsilver03

NO2allowes a vehical to produce more power because it has more oxygen volume wise compared to atomsphere, which alows the engine to burn alot more fuel=more power, if it is added with no more addition fuel it will cause an exterme lean condition. i would never use just a bolt on system without running a wideband 02. A turbo just compresses the air and forces it into the cylinder, and can allow it to exced volumetric efficency... neat if you ask me. they are both just diffrent approaches of allowing more oxygen into the cylinders to allow more fuel to be burnt. one good part of NO2 is the it cools the intake charge which helps against detonation, where as a turbo heats the intake charge. well im tired of explaining. i would never use NO2 on a street car and i have ruined an engine with a turbo. buy a bigger bike

robustus0007,

The biggest problem with nitrous is a lean condition. Either run a "wet kit" which adds more fuel with the nitrous, or only use a small amount of nitrous and only for short periods of time. Otherwise you are risking melting your pistons and destroying the entire motor. If it fails bad enough it can take out the pistons, head, and cylinder walls. BE Careful.
