i used to have my bottle mounted behind my seat and the blowdown tube ran right through the floor no problem(its a solid one, comes out the top, does a U and through the floor). i will be mounting the bottle in the center of the rear deck right above the gas tank and was wondering what you guys have done about a solid blowdown tube in this location.

the bottle will be bolted through the carpet to a peice of wood for simplicity but im thinking i MIGHT be able to drill a hole carefully to let the tube run through to the outside, although im not sure if theres an area for the tube to blow out towards and not directly into the tank. any ideas or things you guys did to help?

 

this is probably your best bet...

i know it is i really dont wanna spend the money for it.lol. how long is that line Ray? would the best spot for it be right down into the t-top well?

anybody know if theres space for the tube to blow towards the ground and not directly into the tank?

 

the kit comes with a 3 foot line ... this can be lengthened if you need it to be...the *an hose is $9.08 per foot

 

I agree. Although it is a little pricier versus a standard blowdown tube, it lets you nail a custom configuration right on the money.

 

Or you can just run some cheap hose for your blow down tube. What in the world do you need this braided line. Unless it is for asthetics, there is absolutly no need for it. Braided line does to things. Looks great and holds high pressure safely. With a blow down tube worst case scenario is you just filled your bottle and left your heater on and it blows out 1200 PSI of N20. ANY HOSE WILL DIRECT THIS OUT. If you want something stronger then use some twistlock hose and ends for less than 1/2 the braided price. Hell it would be cheaper running a hard line bent by hand. More than $20 for a blot down tube is just insane. There is no engineering needed, it is just a hose that vents to atmosphere. There is some pressure in it while the N20 is flying though, but that will be so short a time and so low a pressure that there is no need to worry. Why is the pressure so low you might think. It is coming out of a 1200 PSI bottle. It is low due to the VERY high velocity of the gas. The faster it moves the less pressure there is in the line. Thats why if you take a paper staw, get it wet and blow through it, it will colapse. The pressure outside the straw gets higher than the inside and it collapses. This is also what happens to your brake lines when they start getting old.

In short, just get a hunk of fuel hose from autozone, and buy the right fitting to make the connection. Then just vent under your carpet or something. In the event you blow your cap and vent all your N20, just pull over and let the car air out for a minute. There really is no need for a hole in the floor if the bottle is way back there. Nitrogen expands to 2000 times its liquid form, when it turns to gas, that means your interior will fill with N20 for a little bit, but that also means that it will disipate very fast too.

I think the issue is being very over complicated. Hope this helps.

 

I am almost speechless after this post....I agree the kit we sell is pricey but sometimes safety costs. This is one of my pet peeves....people complaining about safety items...helmet, roll cage, fire jacket, etc. These rules are in place to protect your life....don't know about yours but I think mine is worth alot more than any safety item.

Here are just a few things wrong about the above post....
1) in the event of a disc rupture if you are using a flexible hose it will turn into a whip, this is why a bulkhead fitting is required...placing it under your carpet is downright stupid.
2) due to the Nitrous displacing the Oxygen in the cabin of your car, you could suffocate...Or in a simple term you could DIE...try pulling over while you can't see or breathe
3)The sulfer mixed into the nitrous will make you sick if you inhale it.
4) The burst disc ruptures at 3000psi

 

I very well agree with Nitrous Dave,
I think there is another safe option to still allow this to be cheaper.
The price of this kit isnt bad, go price check any AN fittings and you know where your money is going in the price of this kit.

The only other safe alternative that really comes to mind, without using a bulkhead fitting attached threw the floor of the car would be fabricating a hard line something comparable to the size and strength of a standard blowdown tube, but then you would still need to find a fitting and a way to flange the pipe you made to work with the bottle.

 

Stunned as well Ray. You must have -8AN hose for the blow town to meet (atleast local drag rules) Any bottle mounted inside of the compartment must have a blow down. As far a "pulling over" at 120+ mph on the strip there is no pulling over.........I ran mine down inside of the old spare tire well where there is already a hole ( I belivee there was anyway) and put the bulkhead in there to blow through.

Overcompliated??? Every thing in your post was definately not thought out. Nothing about being safe and doing it right is "overcomplicated"

 

Please, before you post, actually know what you are talking about. Don't just assume you know. Assumption is the mother of all F ups.

 

The expanding N2O also cools the air, and will condense the moisture in the air to form a fog that blocks your vision.... pull over at 120mph, blind and gasping for air. That's a hoot.......

The "hose" acts as an orifice. At the point the N2O is exiting the bottle, it is at the rupture disc pressure. The pressure then drops through the hose, until it reaches atmospheric pressure at the discharge point. A good portion of the hose will be exposed to pressure above 1000psi or more.

Wow!
