Nitrous is actually pretty safe on Diesels. It is way more easy and safer to use on a diesel than on a gas engine. I have had a couple pretty big nitrous pops, didnt even shut the engine down.. nothing too it.

As for the bottles it would be alot, especially when I am already chasing weight on the truck

In CGA pamphlet C-6.1, "Standards For Visual Inspection Of High Pressure Aluminum Compressed Gas Cylinders", it states that cylinders heated to metal temperatures in excess of 350oF (176oC) must be condemned.

Common evidence of exposure to elevated temperatures that may heat the metal temperature to 350oF (176oC) include:

* discoloration, charring, or blistering of the cylinder paint, protective coatings or labels;
* distortion of the cylinder;
* melting of non-metallic (i.e. plastic, etc.) valve components;
* activation of valve pressure relief device; or
* activation of a heat indication system

Catalina Cylinders recommends that if there is evidence, or it is believed, that a nitrous oxide cylinder has been exposed to temperatures above 125oF (52oC) but the temperature of metal of the cylinder is not believed to have reached 350oF (176oC) for any duration of time, the cylinder must still be subjected to hydrostatic testing or condemned. A cylinder that has been exposed to temperatures great enough to change the temper of the cylinder could show an increase in total or permanent expansion as measured during hydrostatic testing. Cylinders showing unusually high total expansion or exceeding the regulatory limits for the relationship of permanent expansion to total expansion (i.e. DOT = 10% and TC = 6%) should be condemned.

DOT 3AL and DOT 4E aluminum cylinders subjected to fire must be removed from service according to section (f) (4) of CFR 49 part 173.34, "Qualification, Maintenance, and Use of Cylinders". No testing for acceptance or re-heat treatment is authorized.

nitrous oxide is not combustible! it is an oxidizer!

no kidding! however, it readily supports combustion which I suspect is the real reason it was mentioned in the cited article! always remember, overexposure to nitrous oxide can cause death by reducing the level of oxygen below that required to support life!

Because it is frigging retarded, let the gasser racers drive around with bombs under their hood.
you ever seen what happens when a half full of gasoline is lit with a match?

nitrous isn't flamable

and how often do you see nitrous bottles under the hood?

Just reading through this. For anyone else interested, portable compressed gas cylinders are federaly regulated by the Department of Transportation.

In addition to that, if any of you choose to paint or powerdercoat, the cylinder should have a DOT conformity stamp somewhere on it's body. Don't cover it up and it will save you headache.
Also, any store setup to test and refill fire extinguishers should be more than willing to take your money after hydrostatically testing and re-certifying your tanks.

If pussies like Gene realized how many vehicles in the US have hydrocarbons for rerfridgerant, nitrous oxide would be the least of their worries.
