i know that a bottle blanket defenitly helps maximize the potential of your nitrous but is one actually needed? will i hurt something if one is not used....im not going to be spraying in winter...

 

I think the blanket is more to keep heat away than it is to keep heat in. If you have an thermostat-controled bottle heater that'd be all you need to get it at the right temp. The blanket would be used to keep the bottle out of direct sun-light if you were to have it by a window or something. You definately don't want your bottle to be toasted all day by the sun as it sits in a parking lot.... Take it out on real hot days.

 

o well a better question then...is a bottle heater absolutly necessary???

 

Definately unless you can manage to constantly keep a full bottle. A full bottle will be around the right pressure but as soon as you start making nitrous runs the pressure will start to fall and you'll steadily lose performance.

...You COULD use a "ghetto bottle heater" aka a propane torch BUT thats quite risky (although a LOT of people do it).

 

Yea, but they’re illegal at the track.

 

wow, i never heard that before, LoL

 

Whats illegal?

 

using propane to heat the bottle.


its also stupid.
i know people do it.

if you're one of thoes people. please. dont tell me. i dont want to know.

 

Oh I thought you may have been talking about bottle heaters in general being not allowed at the track. I completely agree that torching a bottle is borderline insane. I added that comment more jokingly than anything else. Maybe I should added "if you're insane and suicidal you COULD...."

Anyway, how about I retract my torch heating idea for a less-risky means of "ghetto bottle heating" ...a tub of hot water.

 

blankets are illegal at the track? how so?

 

i hope theyre not.....that would be a waste wouldnt it?

 

the NOS ones are thin as paper, but the ones made by NX are MADE BY IGLOO of the same material as the soft sided coolers and wrap all the way around the bottle with velcro attachment sinch straps.

 

I think that if you only use the juice on the street its not necessary. I have been shooting for years without and I have never had a problem.

Auggie

 

ill be using the juice in the street, on the track (but the car wont see a whole lot of track time) and as silly as this may sound, for looks. im having the bottle painted pearl white to match my car and am gonne airbrush some sort of bowtie (in red) on the middle of the bottle. the reason i asked is ive seen millions of people running around the street and strip without a bottle heater whatsoever...i mean if it was necessary dont you think it would be included with ALL nitrous kits???

 

Believe me, a bottle heater is ABSOLUTELY needed, a bottle blanket isn't. Like I said, with a full bottle you'll have around the proper pressure but as soon as you start using it after a few runs the pressure will begin to drop real fast. Not enough bottle pressure = rich condition = your car will get slower and slower with every run. I'm not talking a little slower, I'm talking considerably slower.

 

Holy ****, are you serious? People do that? What if you had a slight leak that you didn't know about.....yet?

 

man if thats the case they should include that with their kits, kind of like ripping you off ya know?

 

yea lol........."hey yall, check out this way i got out of buying a bottle heater..." BOOM!!!!!!!!!

 

CamaroRUS, how about a pic of that bottle when you get it painted??

Auggie

 

you know it man, i cant wait until winters over., hopefully the car will be mostly done

 

nitrous is NOT flammable. The thing you gotta worry about is if the metal bottle were to fatigue you have 950+psi of pressure waiting to "explosively" escape the bottle.

 

Your right, I forgot about that. I'm going to claim that it was earlier when I posted that.

Nitrogen and oxygen, neither are flammable.

 

the best way I have seen so far for maintaining bottle pressure uses a nitrous bottle with a gauge fitting built into the valve. Instead of using that fitting for a gauge it is hooked to a second bottle full of nitrogen with a welding style regulator set at 900 or 1000 PSI.

normally as the nitrous plays out of its own bottle on a pass where high flow is used (like 150 to 300+ shots) the bottle cools and the pressure normally drops and flow is decreased.

In this case the nitrogen is keeping pressure pushing down on the liquid nitrous from above and forcing it down into the pickup tube at the same pressure for the entire pass because the nitrogen is at such a hig pressure it never drops below the regulator setting. The entire pass takes place with 900 or 1000 or whatever you have it set at PSI regardless of the fact if the bottle is 20 below or 100 degrees.

 

wow great info

 

Far out:hail: .

Ok, just to clarify my statement towards the beginning… bottle heaters are illegal at the track. If your track is doing a full NHRA or IHRA tech inspection and knows that you have spray (at the local tracks around here, if the tower sees you purging or making a pass that you’re obviously spraying they pull your tech card to make sure you were teched for N2O), they should check your bottle for a blow off/blow down tube, valid date and if you have a bottle heater they will require you to remove it before you can make a pass.

 

I've never heard of that or know anyone whos been haggled for having a heater. Right about now I wish I had a rule book because online this is as much as I can find:

"If using nitrous oxide system: All bottles must be securely mounted, stamped with minimum DOT 1800 lb. rating and identified as nitrous oxide. If bottle is in driver's compartment, it must be equipped with a relief valve vented outside of driver's compartment. System must be commercially available and installed per manufacturer's recommendation."

 

Yeah Im curious about this no bottle heater rule as well, where does it say that you can't have a bottle heater. If the bottle is the right date and has a blowdown tube why cant it have a bottle heater?

 

so besides the bottle heater if i were to paint over the bottle it would be illegal at tracks since there is no label anymore?

 

I’ve been nailed a 3 different tracks for my bottle heater, so it’s not just one track. The one that I usually run at will make you leave it at the tech booth to make sure that you don’t just reinstall it in the pits.

As far as paint/label I’m pretty sure you’re OK unless you fill/polish out the stampings of the rating and cert on the bottle. If you need a new label I know that NOS and some others will send them if you ask.

 

does your bottle heater prevent the use of a down tube? what rule are they citing?

 

Why would it prevent me from using a blowdown tube? FWIW, I'm just using the NX setup that uses a blanket and a pressure transducer which keeps the bottle at roughly a steady 950psi.

 

no need for blanket...heater is very nice though, very important for fall events but good in the summer too.

 

Im just wondering because there are real NHRA techs at Bandemere for certifying and they do some of the track tech and they have no problem with the bottle heaters. Are they missing something?

 

I’d have to look for it or ask around, and don’t really have time. One of the tech guys at the track I run at most is the one of the regional inspectors for certifying cages and stuff so I never actually questioned it, I just did my best to hide the bottle and N2O to avoid any hassles altogether (purged through the engine during my burnout so no one noticed anything funny, then add a progressive controller and no one is the wiser, just a stock looking, stock sounding LT1 running high 10’s at 120 on radials…)

 

I would be very curious to know because this worries me.


my friend Kendal came up with the ingenius idea of using a $20 driving/fog light kit to use as a bottle heater. pointed right at the bottle in his trunk it works awsome. he has to pay close attention to it for safety becase there is no pressure switch on it.

 

If your using like 4 lbs per pass.Put a full bottle in after every pass
and torch em.I dont think putting the blankey on is going to do much it looks cool though.
If you only got 75-175 pills why not try a bottle heater?

 

actually oxygen is flammable...very flammable. it's just when it's combined w/ nitrogen that it changes.

the reason a candle will go out if you put a cup over it? all the oxygen is burned up

 

have you ever watched the discovery channel with Jessie James at west coast choppers?

Have you ever watched him build a fuel tank by hand by hammering out a piece of aluminum on the leather cussion?

have you ever noticed what he does to make the aluminum pliable enough to hammer out into some other shape?

 

He anneals the aluminum by heating it above 400* and then cooing it quickly.

Unless someone is a complete flaming moron, they’re not going to heat the bottle or any particular spot to 400* F (a propane torch doesn’t put out enough heat to get a piece of aluminum that big that hot, at least not easily) and then quenching it.

 

flame + bottle = flaming moron

Jessie James does not hold the flame in one spot either

the annealing process could take place over a long time with the persons using the flame doing it a little at a time until the bottle fails.

The worst part is that as a nitrous refiller I know that the bottle sees no higher pressures than those when it is being filled, making the bottle filler the person who is most at risk of exposure to explosive failure.

 

Actually, no… annealing aluminum doesn’t work that way, you’ve got to get it hot and cool it, and if you let annealed aluminum sit around it will eventually normalize on it’s own, there is no chance of it annealing over time.

JJ does it using a rosebud Oxyfuel torch which puts out many times the heat that a propane torch does on a piece of aluminum that is a fraction the thickness of an N2O bottle (cut one open, you’ll be shocked how thick they are).

Am I implying that it’s a safe way to do it? Hell no, we live in a world where people manage to win liability suits for coffee that’s too hot… I could just see some jackass locking a torch on, pointing at the side of the bottle and walking away…

 

*** damn i hate when people automatically assume when that since n20 is used to make ur car go faster and its something that blows up inside the engine , that it is flamable

let me tell all of you who thing N2O is flamable, its NOT FLAMABLE

just for your info

people are not that stupid to put a blow torch to a highly compressed flamable gas

 

Oxygen is not flammable. You could hold a striker in a stream of pure oxygen and not have anything happen unless you had a reactant present.

It requires a fuel to react. Flames with pure oxygen [as in an acetylene torch] burn hotter then a normal flame because the oxygen content of air is approximately 12%. In the case of the torch, acetylene is the fuel.

Don't feel bad. I was having my bottles filled this weekend and was smoking out the back door when they came over to fill my bottle. Then I asked the "Is it ok if I smoke while you're doing that?" question, and the response was "Yeah, it's not flammable".

 

O2 is not a fuel, but just about everything becomes a decent fuel in any decent concentration of O2

 

How to make a cheap bottle heater part 1.
go to the breakers yard
find a car with heated seats
rip out the heater pad from the seat
wrap it round your bbottle
get a 950psi pressure switch and place in series with the power for the heater(you may need a relay)
et viola, optimum bottle pressure
