NOS

[AJ]

how many 50 shots per pound of NOS?  how much is safe on stock internals too?  thanks !

[Tuck&Poke]

nothing is good for a stock engine especially in the long run. its better to spend like 250 on pistons then spend like 600 to fix the engine after the damage is done.

[ca18guy]

NOS is no different then a turbo, they both do the same thing, force more air into the engine. He wants to know how often do you need to refill a 10lbs tank of NOS. If he is running a 50 shot how many runs can he get out of it?

[xLSTONEx]

NOS helps combustion, and isn't flammable, and in no way does it force more air into the engine.

[jd90240sx]

Nos doesn't force more air into the engine! I allows more air and fuel to be burned in the combustion chamber which makes your car faster.

[ca18guy]

OK if we want to be technical about it. It doe's force more "oxygen" into the engine by the fact that the NOS is mostly oxygen, it burns the extra oxygen there for creating more power! Now back to the question, this isn't about how NOS works. He wants to know how often do you need to refill a 10lbs tank of NOS. If he is running a 50 shot how many runs can he get out of it?

Might I add that you contradict yourself in your post. It does'nt force more air but allows more air to be burned? If not for the NOS where doe's the extra air come from? NOS IS forced induction, just a different way of doing it.

[AJ]

thank u ca18guy <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/wink.gif" border="0" valign="absmiddle" alt=';)'> ur the only one who knows what i'm tryign to figure out <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt=':)'>.. hehee,, soooo does anyone run nitrous? and how often do they refill their dang tank!

[misnomer]

hehe, yer both right. It's not forcing any air anywhere. I'm not saying this from a point of expertise, as I have no frikkin' clue how exactly NOS works. However, as I see it it's a density issue. Either by cooling process (cooler air == denser air == more O2 == bigger boom), or just the fact that NO2 may be denser then your typical outside air, it gets more oxygen into the combustion chamber. Not by force, but by the simple fact that there is more of it availiable outside the chamber.

Of course, I'm just talking out of my ass here, so don't flame me. Methane can be highly flamable <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/tounge.gif" border="0" valign="absmiddle" alt=':p'>

[ca18guy]

Compared to the density of air nitrous has 70% more oxygen then air. Nitrous is &quot;classified&quot; as forced induction, thats why I said what I said. The point I was trying to make is what's the difference between getting 50 HP from nitrous or getting 50 HP from a turbo? (i'll answer my own question) There is no difference!! Now back to the question at hand!!! If he is running a 50 shot how many runs can he get out of it?

[IceTekGuy]

&quot;NOS is mostly oxygen, it burns the extra oxygen there for creating more power! &quot;

umm dude, NOS is NO2 NITROUS OXIDE not OXYGEN
NOS is combustible when it has proper amounts of fuel and air mixture added to the nitrous oxide hence have more combustion, giving you the &quot;QUICK FIX&quot; of speed.

hahaha, this is getting downright hillarious. Ca18 is correct btw. When NOS enters the combustion chamber, the oxigen breaks away from the nitrogen. The oxigen is what's combusting. The nitrogen actually has a cooling effect on the engine that helps keep it from overheating too.

Exactly...took the words right out of my mouth (6 hrs before I even read the post :cheesy: ). &nbsp;Air is roughly 21% oxygen...the rest is nitrogen, an inert gas that doesn't participate in the combustion reaction (hydocarbon (gasoline) + O2 ==&gt; H20 + CO2). &nbsp;Nitrous (oxide) is roughly 66% oxygen and 33% nitrogen (inert gas) on a molar basis. &nbsp;You may not be cramming more air in there...but you're cramming more of what really matters to the combustion reaction in there: &nbsp;oxygen. &nbsp;Therefore, it IS forced induction. &nbsp;Nitrous oxide is NOT a fuel. &nbsp;The gasoline is the fuel...nitrous just adds more oxygen to allow more fuel to be burned per combustion reaction (per stroke of the piston), thereby creating more horsepower.

[LanceS13]

I just did some oversimplified and assumption-filled (and probably flawed) calculations to find an estimate of how much nitrous would be used in a run. &nbsp;It's the best I can do b/c I've never run nitrous before.
1 lb. = 454 g
so I'm guessing a 50 shot will give roughly 25% more power which is roughly 25% more oxygen...which would call for about...
.25 x .6 L (per cylinder) x (1 mol/22.4L of ideal gas) = .007 mol NO2 per combustion = .31 g of NO2
Estimate an average rpm of 4800...
4800 rpm x (1 min/ 60 s) x (15 s/ run) = 1200 rotations per run and you use nitrous for I guess about half of that...so 600 combustions per run with nitrous.
600 x .31g of NO2 = 186 g of NO2 which is a little less than half a pound. &nbsp;So one pound would give you about two runs.

****DON'T TAKE THIS AS FACT. &nbsp;IT'S JUST MY ATTEMPT TO SOLVE THIS PROBLEM WITH CHEMISTRY B/C I HAVE NO EXPERIENCE WITH NITROUS OXIDE...AND BECAUSE OF THE MANY ASSUMPTIONS INCLUDED IN THE CALCULATIONS, IT MAY BE WAAAAYYYY OFF! &nbsp;But it gives you idea at least (hopefully a fairly accurate one).
:biggrin:

[ca18guy]

Well I'm amazed you went through the trouble to do that *clapping hands* Remember though most runs with nitrous won't be for a full 60 sec. It would be more of a quick thing to beat a person from a stop light, so if it take's only 11 seconds to get through a 1/8 of a mile then you can get almost 6 runs in 60 sec. (if that makes sense)

What can I say...I'm a bored ChemE student. :biggrin:
But I actually calculated for half of a 15s run...7.5s on the bottle.

But now that I think about it...by 1 lb., he probably means 1 lb of pressure, which would be pounds of force and not pounds of mass. &nbsp;If this is the case, then my calculations are probably really way off...but whatever.

Dood, a 50 shot of Nitrous really doesn't do that much. I think a stock KA can handle about 75.

Lance, &nbsp;sorry to tell you you are a bit off, &nbsp;actually way off. &nbsp;Remember the assumption you made of an ideal gas? &nbsp;It assumes standard temperature, and pressure, &nbsp;unfortuneately the NOS isnt at STP therefore the calculation is useless, remember the NOS is in liquid form then turns gaseous resulting in a frigid temperature so the assumption of 22.4 L/mole of ideal gas is invalid, &nbsp;BTW you dont take into account what happens when the molecule of NOS decomposes to increase the volume in the chamber. &nbsp;The calculation is possible but requires many more variables. &nbsp;In case you want to know I have my BS in chemistry and am in grad school right now.
I applaud you for your effort though

Thanks...and I know. I said it was probably way off b/c I did assume ideal gas and there are many other variables that I just kinda conveniently forgot about...including the nitrous decomposition, phase change, expansion, temp and pressure differences, etc. etc. For a truely accurate number, that would be one heck of alot of calculation and I would have to have alot more information and it would probably end up being way beyond my current education.

But anyway...this goes to show: No matter how smart you think you are, somebody's always going to know more than you....especially when you're still a sophomore and they're working on their masters:).

[ca18guy]

Sorry brain fart on my part, it is N2O, 2 molecules of nirogen and 1 molecule of oxygen. Here is the exact words off the NOS website

To your engine, nitrous oxide is a more convenient form of normal air. Since we are only interested in the oxygen the air contains, nitrous oxide provides a simple tool for manipulating how much oxygen will be present when you add additional fuel in an attempt to release more power. The power always comes from the fuel source. Nitrous oxide is not a fuel. Nitrous oxide is a convenient way to add the additional oxygen required to burn more fuel. If you add only nitrous oxide and do not add additional fuel, you would just speed up the rate at which your engine is burning the fuel that it normally uses.

This, more often than not, leads to destructive detonation. The energy comes from the fuel, not the nitrous. Nitrous oxide simply allows you to burn a greater quantity of fuel in the same time period; thus, the overall effect is a tremendous increase in the total amount of energy, or power, released from the fuel and available for accelerating your vehicle.

There is no voodoo involved in nitrous oxide. In effect, using nitrous is no different from using a bigger carburetor, a better manifold, a supercharger, or a turbocharger. Understand that the air you and your engine breathe is made up, at sea level, of 78% nitrogen, 21% oxygen, and just 1% other gases. Nitrous oxide (N2O) is made by simply taking the 2 major components of earthÕs atmosphere (in this case 2 molecules of nitrogen and 1 molecule of oxygen) and attaching them together with a chemical bond. When the nitrous oxide goes into your engine the heat of combustion breaks the chemical bond to provide your engine more oxygen with which to burn fuel. As youÕve read, all race engines operate under the same principles: more air (better breathing, supercharging, turbocharging, or nitrous) plus more fuel in a denser vapor equals more power.

Finally someone with NOS to answer. I was gonna say I thought nitrous cost's only $5 a pound but I was'nt sure.

[drifterx]

i was wondering, i am not a fan of NOS but i was thinking of running 50shot, is there 25 shots?
i have 120000 miles on my car now.... i put over 18000 in 9 months.... would i have a problem and does anyone know when i expect the engine to die? with or without the NOS, i wanna compare...
what is better ZEX or NOS?

[ca18guy]

You have alot of miles and it seems like you drive it alot, but if the engine is in good shape then NOS would be OK. Probably get a compression test to make sure that it's in top shape. I would get NOS, you can get a 25 shot, you may have to order a 25 shot jet (the thing that controls how much nitrous get's sent through the tube) &nbsp;as for when your engine would die.... there is no set limit it could happen in 1 mile or you could get to 500,000 miles, just make sure you mantain your car.

[drifterx]

where can i get a compression test and how much do they usually cost?
can u tell if my compression is good, if i ran a 16.11 on a wet day with a slipping clutch?

[ca18guy]

Take it to a mechanic and ask them to run a compression test, it's should'nt cost to much. You ran a good time but that does'nt meananything really (that's like trying to tell if you have old oil in your engine by taking to the drag strip and seeing if it run's a good time <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt=':)'> )

well now , my 95 has 120k and still runnin strong. and dont waste your time with a &quot;25&quot; go with a fifty always stay over 2000rpms and dont take it to the limiter , peak hp on a ka is closer to 4400-5000 range anyways . the zex system is an easier install but the nos kit is more tunable and can be maintained easier.

[BlankFlip]

would u all recommend NOS on an engine w/ 21k miles on it? n also, is NOS not street legal eveywhere?

[ZeroGS14]

LOL I'd like to say all the reply's to this topic have been, in the least, have been entertaining. =D

Any hows I started running 100 shot nos in my ka motor with 40,000 miles on it...it now has 100,000 miles and still is doing ok. &nbsp;The key to nos is to make sure you have enough fuel for the extra oxygen that the N20 provides without going over board on the amount of nos you use. &nbsp;I ran a direct port wet system...meaning that the nos is injected into each individual intake runner with fuel (dry would be without extra fuel being added via nos foggers) through foggers (versus a single fogger which is just one fogger plumbed in somewhere after the air filter and maf sensor). &nbsp;As far as how many runs you can get per bottle ( in this case im referring to a 10 lb bottle) it varies; running a 100 shot I got 4 to 5 really good runs on it and then the performance kind of dwindles as the bottle pressure dropes. &nbsp;NOS usually runs 3 bucks a pound around here. &nbsp;As far as NOS versus ZEX...me personally...I rather use NOS just for their reputation and the simple fact that the solenoids that dictate the release of the nos/fuel are a whole lot closer to the foggers then the ZEX kit places them, which means the n20 has less distance to go to the fogger...and their is less wasted nos lossed in the lines. &nbsp;Hope that helped ya out some..if not lemme know =D

[BlankFlip]

nebody have ne pros for the venom kits? like it better or worse compared to others like nos or zex?
