Well I was thinking about putting a bottle in my spare tire compartment....just to have that hidden look...

Now what Im wondering is what will happen if somone hits me on that side where the bottle is at?

 

Everything Blows up in a burning inferno and the world implodes.

Nitrous doesnt explode and i dont think the bottle would get hit hard enough and in the right area to puncture it.

Im probly wrong about the puncture thing, but those bottles are strong as ****.

Tony.

 

If a collision were to break the valve off or open you would have an instant pressure release of course. This would displace all air within the car until new/fresh air could recycle in. All visibility would be gone too as occupants would be enveloped in a dense white cloud. It would be possible that the liquid nitrous oxide could make contact and anything touched would be instantly frozen. The jetting bottle contents can also pose its own risk. It is unlikely but if the bottle where to be torn from the clamps and the valve broken off, it would be a projectile if not confined otherwise.

 

Bottles are strong, but like the post above states, its not uncommon for the valve to be broken off when striked hard enough. In an accident with enough force, the bottle could get sandwhiched between the incoming car and the frame rail in spare well, and rupture is a possibility.

IMHO, it is something to be concerned about. I mount mine back there too, but it will only be back there to and from the track, since thats about the only time i'd spray. But I wouldn't make it a habit to drive around with it back there.

 

This brings up a good point. Preparation is key and following the rules is paramount. First things first, I don't know how to mount the bottle safely other than welding the bottle brackets to some steel stock and welding it to the car. The metal skin of the car back there is pretty thin and I don't see how trying to bolt the brackets can provide ample enough strength which seems to be what alot of people percive as a dangerous condition.

The big Hollywood Nitrous cloud enveloping the car as mentioned in previous posts can be easily averted by employing a blowdown tube. Any more beyond this and I think you need to drive a Hummer for more security. With that I would like to debut my setup.

I can post bigger pics later, I just wanted to get these up. Sorry I didn't take good pictures during the process. It just turned out so good I couldn't help but paint it. I know the black paint does make it harder to discern.
Basically I started with a standard NOS wet plate kit. I did get some 1" steel stock from home depot and formed and welded the support brackets. I did have to cut the NOS bottle brackets in order to have the fasteners facing inward. I am working on making a custom battery box that is going to fit in the BMR batt relocation platform below the NO2 bottle. I had to cut the "ears" off the BMR unit and re-weld them to face well rather than hold on top as originally designed. This was all due to getting the batt low enough to fit under the bottle.

I am using the NOS solenoid opener. I have the switch mounted in the center console along with my flashscan. The center dash console: Left most fog lamp is still fog lamp, going right, bottle heater ckt, Stage II activate, and right most foglamp is master NO2 arm which is hooked up to a single pull, double throw relay that applies 12 to the WOT sw and a ground for PCM red connector pin 56 for EFI Live's custom OS #5 which knows to pull timing and add fuel. This is a hardtop car that never had TCS. Those buttons on the console are for a QTP cutout and a Line lock. The Line lock master arm and NO2 purge are in the ashtray.

From the bottle, there is NOS opener, electronic bottle pressure regulator, 6 AN line to a "Y" then two 4AN lines to the airpump area up front to two stages. The NOS plate is not astectically pleasing with the two Y's sticking out of it, for that matter it's not really good looking at all...I just got ahold of it for a song.

I have not moved my batt back yet- when I do get the box done I am thinking about putting a standalone fuel cell/system in it's place.

I am using the autometer fuel pressure sending unit off the rail and recording with EFI Live.

The stages...First stage is right off WOT, the second is pretty neat. I made up my own homebrew ckt that taps into the pcm and fires the second stage after the 2-3 shift.

The first trip to the track with this setup was interesting. This being my first NO2 setup I had no real idea of what to jet given the frankenstien setup. I tried to shoot down the middle and ended up with this.

1st run -on motor 12.3 @ 110 w/ 1.8 60'
2nd run -on both NO2 stages 11.1 @110 w/ 1.6 60'

As the second stage kicked in I heard a POP. Went back to the trailer and found the MAF screen laying on the filter and 5,7 plug electrodes disintegrated.

Everything is still alive and I found the calculator on Dynotune's site and ordered more jets.
Need to get the roll bar in now.

 

Ok so if I put a blow down tube on there and it is SECURELY fasened down....I should be good to drive it daily with the bottle in there?

 

There are no guarantees if you get hit hard enough in an accident. The burst disk isn't going to be able to release the pressure quick enough if the bottle was to get damaged, and even then it may no longer be the weakest point in the cylinder.

Barring that unexpected happening, as long as you have a blowdown tube and the bottle is secured, it will be safe to drive with the bottle in the car.

But like I said, personally I wouldn't drive around with a bottle in the car unless I knew I was going to use it. Having 10lbs of a strong oxidizing gas near 15 gallons of gasoline in an accident can be the difference from getting pulled from a burning car vs. having nothing left to identify you with but your watch.

 

hmmm damn...

 

wow. i'm going to duct tape some fire extinguishers around my bottle and and relocate my gas tank on top of my passenger t top.

 

you would get a sweet instant center with the gas tank up there lol

 

I asked the same question months ago... and to my surprise, not too many people were concerned. My concern is not the bottle getting punctured, or even the valve getting sheered off (although a loose bottle with a sheered off valve will make an awesome projectile), it's the bottle itself being launched into the passenger area (C5 so it's even worse than yours). I put a safety strap on it. It is barely noticeable in this pic but it goes through the brackets and is secured to the release brackets. I have a clip on one side so I can release it if necessary.
Do the math... (mass x velocity) a 15 lb full tank weighs 36(ish) lbs... in a 60 mph hit will be 2160 lbs force traveling at your head. (or as one guy said in my thread... "at your wife's head")
