g day ppl

just curious about NOS, any one runng it atm or run it befrore?????

iv heard it is really dangerous??

any and all info would b good

thanks ppl

There's 2 system DRY and WET.

The DRY system is the not so safe way but it cheaper, as you add the NOS to the fuel feed pipe so you can't give high doses and it needs to be at a lower amount than a WET system.

Because if you try to pump in too much you could get a back flash where the left over NOS in the fuel pipe will explode.

A WET sytem is the safer yet deaer system, It's deaer because it takes a bit more skill to install etc.

Anyway, how a WET system works is that the fuel and NOS are mixed at the injector, so you'll need a need injector the NOS kit will includes these, The reason why it's safer is that you can't get any back flash so the fuel pipe won't explode etc.

You can buy kits yourself and install them yourself these include both types of kit.

A kit has a computer and links up with the ECU etc, and injects some much NOS at the right times as you can see you need to know what the right times and the right amounts are the reason why it can be unsafe.

Before you go and get NOS thuogh, you'll want to have forged everything in the engine, this means forged pistions, con-rods, crank sharft, etc other wise the first time you go to use it the NOS will shove a pistion through your engine and out the other side maybe even completely out the car.

An example of the speed:

No NOS

your doing 140klms along a road, put the foot down and it might take 8 seconds to get to 200klms.

With NOS

Your doing 140klms along the road, put the foot down and hit the button in 1-2 second your already over 200klms and getting really shoved back into the seat.

Cmon... NAWS is cheating (/me hides from 2rismo)

LW.

You dont need forged everything with a NOS setup, you can run a low hp shot 50 ~ 75 without harming your motor as long as its not on the edge of its peformance limit with stock internals. Most people hook nos up to give them the added power to thier stockish motor so you dont have to spend thousands to make it that powerfull 24/7.

[funkymonkey]

did you know that if you heated your engine up to a really high temperature itd make its own naws? No really, Nitrogen Dioxide is formed at really high temperatures due to the covalence of the nitrogen and oxygen molecuse. providing the oxygen hasn't been used up already int he combustion.

No. Couldn't be bothered quoting all the wrong bits.

Anyway,

If you intend on running a relatively small shot (most people run wet kits on their skylines), of about 50-75hp then you can simply run the right spark plugs and retard your timing a little bit.

You absolutely do NOT have to have forged internals to run nitrous. Think about it this way:

You have a stock motor - If you fitted a bigger turbo than stock, bigger injectors and manifold to suit and made an extra 100hp over stock you'd have a certain amount of extra pressure/load on your internal components, (rods, pistons etc).

Then if you take the same stock motor, add enough nitrous to make an extra 100hp, you have roughly the same load/pressure on the internal components as with the bigger turbo.

Just remember, making more power in an internal combustion engine can only happen by burning more fuel with more oxygen. Nitrous Oxide use introduces vast amounts of oxygen so you can burn more fuel - just like a bigger turbo, camshaft change, air filter change etc.

Hope this helps. To see the results of a stock motored R33 gtst running a small shot of gas click here: http://per4mancevids.com/2rismo_11.9.mpg

Nitrous oxide (dinitrogen oxide), N2O, is formed when ammonium nitrate, NH4NO3, is heated.

Copied from HERE

At room temperature, N2O is quite unreactive with most substances, including alkali metals, halogens, and even ozone. It is therefore widely used as a propellant in aerosol cans in place of the CFCs which can damage the ozone layer. When heated sufficiently, however, N2O decomposes exothermically to N2 and O2.

If this reaction occurs in the combustion chamber of an automobile, 3 moles of gas would be produced from 2 moles, providing an extra boost to the piston, as well as liberating more heat. It also has a number of other benefits. The increased oxygen provides more efficient combustion of fuel, the nitrogen buffers the increased cylinder pressure controlling the combustion, and the latent heat of vaporisation of the N2O reduces the intake temperature. Therefore N2O is occasionally injected into the fuel lines of racing cars to give more power to the engine and to give the car exceptional acceleration.

Directly into the fuel lines? Do you have an actual example?

ahh I was talking about NO2, a relatively useless gas fake naws if you wanna call it that.

Okay... Almost EVERY SINGLE THING you have said in this post is COMPLETELY WRONG

Then if you take the same stock motor, add enough nitrous to make an extra 100hp, you have roughly the same load/pressure on the internal components as with the bigger turbo.

Basically yes, but running Nitrous Oxide as opposed to most boost is harder on the engine (especially standard internals) because of the MASSIVE heat cycles it subjects the cylinders and piston crowns and rings to...

When the nitrous is injected into the intake runners/intake manifold, it immediately begins to boil and rapidly expand; the pressure drop will cause the temperature to decrease dramatically. Nitrous boils at 53.9°C below zero.

When it hits the cylinders, COOLS everything immensely.

Then combustion occurs, and an almightly fire burns, HEATING everything up a lot more than what the manufacturers spec'ed it out for...

Repeat this cycle 8000 times per minutes (8000rpm) and you'll soon see how hard nitrous is on the engine.

A small shot like 50-75hp is fine though, and any good condition engine can take that without any modifications.

[funkymonkey]

as merli said the most common reason why engines fail due to nitrous is the instantaneous heating and cooling of a system, a turbo systemon the other hand just gets hotter n hotter. Both are bad, but the quick temperature variance wrecks havoc on the stucture of the bonds in metal, and after a while they give. Its just like a glass, put a glass in your freezer and then pour hot water into it and it'll crack... NOS does the same thing to an engine just on a more grander level.

[Pistolpete]

coolies so just a standard wet shot for about 75hp would not damage the standard interanls. nice.

What abou the whole safety issue, iv heard some really bad thigs like if ur in a small crash the car basically explodes so ur farked.

do they go BANG easily????

also do u need 2 be going high speeds to use it??? and how long would each shot last???

cheers

This thread has some of the most ill informed comments I have seen for a long time.

N2O has been used for a long time and is well tested.

As with any engine, if you increase the power (via a bigger turbo or N2O) it will eventuallt break something. Dont try and get an extra 300hp with N2O (or anything else) and expect your engine to survive for the long haul.

$ for $ N2O is probably the best performance mod you can get.

You wouldn't add a new turbo without dynoing it to set the ignition and fuel up correctly, and the same applies for N2O. Done correctly by someone with experience it is a safe and effective mod.

Do a search in Street rodder sites or mags Street rodder had done a review of 10 wet and dry system that you could install yourself.

In perth a company does NOS installs into magnas they have a great website about NOS in cars.

The reason why I said you'd want to up the internals is so you don't shove a piston out your engine, If your concered about safty then you'll want to really up the internals period.

This is a FAQ by Holly a NOS kits maker.

And a comment like this is just as useless, without qualifying which statements you think are ill-informed.

NOS = Holley. Holley created the brand name ' NOS ' and has been using nos is applications since the mid 70's...
