Nitrous would be good for short track type racing, where you would need power after a turn, or when you slowed down, squirt it for a second or two. If the thing is pretty much wide open, it won't make much difference. I know in full size stuff, 4 stroke applications, it won't give any extra rpm, but in a small 2 stroke (R/C) I wonder if it would. You are still limited to cam size and all the other components that would limit your rpm. Also, as far as being so dangerous, I had an idiot rear end one of my cars, and hit the bottle, and it did not explode. My theory, if it goes fast now, just think how fast it goes juiced! It is like everything else, abused it is not the best HP out there. Blowers, turbos, big compression, all can mess stuff up too, and boom and scatter stuff.

I know thats right!!

But heck nothing like a smaller strong 4 banger with a nicely timed turbo action with the compressin dropped to like 6-7 with a nice 15 PSI comin in!
Supras come to mind!

I agree about if ya want more power throw in a bigger engine, that is why I have a 4 tec pro and a T-Maxx both with Hyper .21's but after throwing on that engine, or getting a tuned pipe you can add even more power with a nitrous kit!

or blow it up!!

Maybe i missed something....
HIPPLE, what are you talking about??? Nitrous will NOT burn your skin. Do know what nitrous is? Its laughing gas, the same stuff your dentist uses to "put you to sleep". Its NOT added to gas, its a gas that is mixed with the air/fuel mixture in the combustion chamber (actually in the intake) which "adds" more oxygen to the fuel mixture to give you more power.
Again, maybe i missed something you said.

Oh and by the way, Nitrous may not be allowed to be used in pro nhra racing, but its NOT banned by the NHRA. Any NHRA sactioned drag racing track that goes by the NHRA rulebook allows nitrous to be used.

I read through the posts so quickly but i could swear somebody was talking about nitromethane? Nitromethane and NOS are not the same thing if anyone was wondering.

From now on maybe "the fast and the furious" should be listed as educational material, because it seems a lot of ppl think "NOS" is explosive, NOS isn't even anything, it's the name of a company that pioneered nitrous oxide injection, it stand for nitrous oxide systems, N2O isn't too practical for moster trucking cuz if you hit that boost going up a hill then you'll just spin the tires, more practical for drag racing, do they even have that???? rc drag racing would be cool, so yeah, it may decrease engine life but so what, and yeah your truck might flip over but it is defineatley not going to blow up!!, as for all this complicated junk ppl are mentioning that only applies to engines with 8 cylinders and four strokes, this is an application to one of the simplest machines in the world, no extensive timing is needed, simply fog N2O in and it works, i built my own system and it works, about the amount of fuel needed going up, when you run your engine it shouldn't be so lean that it can't be leaned any more, so you inject N2O and this leans the mix a bit increases power and rpm, this in turn draws more air into carb, drawing a faster venturi speed, which draws more fuel, add more N2O and it keeps going up and up.

heh

seriously: how would you engage the nitrous - when the throttle is at 80-90%? or using a 3rd servo

nitrous explodes when used in highly compressed canisters and the cannister broken - just like anything other gas..maybe it burned the guys hand because it was under so much pressure and frozen

i once thought of adding more air/fuel to the combustion chamber making some sort of turbine like a turbo but its just not worth it, these cars go fast enough already

nodolarsnosense

a thought nitros oxide was very safe thats why its used. pure O2 is too dangerous so instead NO2 is used because N is very stable (by itself as N2 and i think as NO2)(due to valance electrons)( but you still get the O out on combustion and it does have that cooling effect and stuff

its not in the pressure bottle for safety, its there so you can compress it to liquid to fit heaps more in. so when the pressure is reduced (ie enters engine) it turns to gas but to do this must absorb energy, this is why temps drop as the heat energy is absorbed. i thinkor maybe its just the endothermic reaction thing?
im confused
but go NO2

I still like the sound of “NOS on my RC”.

Some facts and points to ponder: (I’m attempting to cover most of what I’ve read)

The NHRA nor the IHRA has not banned N20 except in anything dealing with a “Stock” class. This includes Stock Eliminator, Super Stock Eliminator, Super Stock Modified and Pro Stock. Everyone else is free to run whatever they like (with strict no-no’s on illegal fuels). The Nitro cars (Top Fuel Funny and Dragsters) don’t need it and I’ll get to that later).

This information comes from memory and experience only so if I miss a figure or what have you, sue me, correct me, whatever. (I deal with this stuff everyday)

Nitrous Oxide CAN burn the skin but its frostbite not like flesh eating bacteria. N2O is not, under any circumstances, flammable. But under certain circumstances it enhances flammability or combustibility when it comes to engines (similar to that of oxygen to acetylene).

N2O is 2 parts nitrogen, 1 part oxygen. Once it has reached a temp of somewhere around 570 some odd degree’s, it breaks down and starts releasing O2, and bunches of it, which makes it mostly O2 at that point and beyond. With this added O2 in an engine cylinder, cylinder pressure increases and can increase to a breaking point. This is where the nitrogen comes in, it acts as a buffer, it actually helps keep the cylinder pressure “beat down” at bit.

If you tuned you carb overly fat (rich), it’ll be lazy, foul out plugs, smoke terribly, and get poor performance. Any engine can only burn but so much fuel at a given time. N2O allows and needs a fat condition. N2O enables an engine to burn fuel that it can’t burn by itself therefore N2O is a catalyst. The more fuel an engine can burn the more power it will produce.

Lower temps:

Of course the engine runs cooler. From the time N2O (in liquid form) hits the intake (or carb), it’s minus 120 something degrees. What do you expect?

Ever wonder why the Nitro methane funny’s and drags don’t use N2O? Go have a look at the periodic table. N2O is lesser than Nitro methane. And wanna know what’s funny? Nitro by itself (although flammable) is very hard to get to burn. In fact, it needs pre-warming and to be compressed (I haven’t the slightest idea of what temps this stuff is combustible). But in an engine, when mixed with a little fuel (gasoline), the “quench” or compression that occurs when the piston approaches top dead center on a compression stroke, all hell breaks loose.

Since nitro methane is the greater fuel, nitrous would ultimately slow the car down. Not to mention keeping a head gasket on it would be forever more impossible.

I’ve lost my train of thought, if you need clarity on any of this or any questions pop into your noggin’, ask away.

I won’t hand you any speculation, only facts.

So first of all nitrous oxide is not flammable like stated above, it is very safe and stable. If somebody wants to discharge a bottle yes it will burn you (I got burned from a leak in my Mustang out of my 10 pound bottle) but also like stated above it is frostbite and not to big of a deal. While running higher nitro methane will in fact give you a similar effect as nitrous if you run is constantly you are going to see higher engine temps and ultimatly a considerably lesser engine life from prolonged high temps. With nitrous you can get a burst of power which will actually run cooler, not because it is boiling from a liquid to a gas either (We are injecting gas only) but because the reaction that takes place between the nitrogen and oxygen is an endothermic reaction. This means when the reaction takes place it actually takes a certain amount of energy with it. In this case heat, the nitrogen atom not only gives a certain amount of buffer but it also helps carry heat out of the combustion chamber. All this combines gives these engines about a 10-20 degree drop in temp. Nitrous does in fact need a rich condition in order to maintain a safe operation and not risk engine damage. With the fuel setup on most rc cars this is achieved in the following manner; as nitrous enters the combustion chamber a more rapid burn occurs, which causes exhaust gases to leave at a high pressure, this in turn increases pressure line and gas tank pressure. With all the raised pressure the engine is supplied with about 64% more fuel running WOT (Wide Open Throttle) than on nitrous than without. As far as activating our nitrous kit goes we have used both a third channel, and the throttle servo (Set to come on at WOT) I hope I have answered all your questions, sorry I jumped around so much feel free to email me at [email protected] if you have any other questions.

Please note that I didn't knock the NOS on RC's. You've posted about it before in which I engaged in conversation about it and how cooj I thought it was. Shorter engine life…yes, plain simple and period. Is that a bad thing? That’s for the consumer to decide. If I wanted the NOS advantage, I’d understand and know the circumstances.

The richening of the fuel you also hit on in the previous thread so I’m aware and I’m glad you pointed that out again for new readers.

I wasn’t trying to “debunk” any theories in my post, and somewhere down the line I was going to get to the advantage and “why NOS will work with nirtomethane RC engines”. I just lost my train of thought due to on going distractions in my home.

I’ll end with this:

If you want extra “oomph” and are willing to spend a little cash here and there, the NOS systems developed and sold by our friend Gear-Head is what you need.

And I have no catchy name for your systems as of current. Should one hit me, I’ll let you know.

Billyman,

I didn't mean to imply you were putting our system down, if that was the implication I gave I appologize for that. I merely wanted to go into some detail on some common subjects with the nitrous kit. I do appriciate your support.

Nah man, I didn't get that impression at all. Just wanting to clear some air before it became cloudy I guess.

I just knew my post was cut short from what I was steering toward and stuff may have been “up in the air”.

No apologies needed.

Rock on man.

How can you say Nitrous isn't flammable?Maybe it releases oxygen and thats what actually burns but if you have nitrous near an open flame...something will happen.

drf

If you put a flame near nitro and heat it up probebly you will manage to burn it.
The oxygen that is released by nitro and gives you the extra power is not alone in the gas. N2O is stable and you will not manage to separate them just by a flame. Inside the combustion chamber pressure as well as heat makes them separate. The N part just goes out of the exaust while the O part makes you engine go wild.

NOS IS NOT flammable. And neither is pure O2.

It's merely fuel for fire.

nodolarsnosense

shouldv learned chemistry in school

N is very stable because of its valance electron configuration. its whats mostly in the atmospere so it tame things.

oxygen cant "burn" itself, it is a reagent in the combustion reaction with carbon etc producing co2 + heat etc

the reaction which happens in cylender

GALAXY

Whatever,don't even need to be open flame...if you inhale it,and blow it through a lit cigartte ,you get a white/blue 2'' flame.Seems pretty flammable to me

Gear-Head

The fame you are seeing is the extra oxygen helping to burn your cigarett, the N2O itself is not burning.

But without the N20,that would never happen.
