    Of course, we're not going to share it with the world until they promise to always be nice to hot rodders.
    And bring back drive-in theaters.
    And reverbs.
    And Slowpokes.

    @Chili Phil needs to bring up hydrazine. I know he's a fan.:)

    Pure oxygen is very reactive. Just a few percent extra makes anything burn twice as fast, and a cutting torch uses pure oxygen directed at red hot steel to make a cut by burning the steel - it doesn't melt the cut, it makes the metal actually burn. There are very clear warnings to keep oil and grease off all the gas fittings for such torches, as pure oxygen can make those burn violently or even explode.

    An engine might survive a slight increase of the airs oxygen content, but any more and I'd expect the combustion to start melting pistons, run into detonation or other such problems.

    Nitrous oxide has several upsides. First, it is stored in liquid form, it will absorb large amounts of heat vaporizing after being introduced into the engine, so it acts as internal cooling at that stage. Great for keeping combustion under control. (Read up on water injection for another example of that.)
    Second, the nitrous doesn't separate into oxygen and nitrogen until it's quite hot = after combustion has started. This process will absorb more heat, and only release the oxygen as it can be used to burn the fuel, there's not time for it to mingle with the fuel charge and cause preignition.

    Oxygen is normally stored in a compressed state, and while it absolutely cools down when expanding (all gases do) it's nothing like the huge energy sink the change going from liquid to gas state is.


    So, to summarize it, pure oxygen is basically too reactive to be handled in the environment we have inside an engine, nitrous works as kind of a slow release system cooling it all down and just releasing the oxygen once it's useful, avoiding all the problems it can cause prior to that.

    If I owned a Tesla :eek: (not that that would ever happen) :p I would sell it and use the money to buy another rod or custom!:D

    The only way I'm riding in one is if they build a he****.

    Sorry man, I was feeling like a 3 legged antelope encircled by a pride of lions. Interesting topic though!

  12. It was done at the Lebanon Valley Speedway in the early 1960s.

    I had heard the story for a couple years of someone doing it however I was never able to confirm it.

    However, it was confirmed to me by the son of the man who did it. The car was a 34 Ford with a Flathead the carburetors were sealed in duct work that ran into the cowl vent which was open for a ram air effect.

    The truth was they had an oxygen tank hidden in the car and were feeding oxygen into the duct work.

    It caused about six foot flames out of the headers, officials knew something was up.

    I have no doubt. Probably lots of unburned fuel in the exhaust continuing to burn in an oxygen rich environment. Hard to get flathead carbs to flow enough fuel to reach stoich in a 100% O2 environment.

    There is a an old antidote about a Purdue University Engineering staff member conducting an experiment on how fast he could light a charcoal grill. He settled on liquid oxygen, and the results were... interesting.

    One of these is a guy named (really) George Goble, a computer person in the Purdue University engineering department. Each year, Goble and a bunch of other engineers hold a picnic in West Lafayette, Ind., at which they cook hamburgers on a big grill. Being engineers, they began looking for practical ways to speed up the charcoal- lighting process.

    "We started by blowing the charcoal with a hair dryer, " Goble told me in a telephone interview. "Then we figured out that it would light faster if we used a vacuum cleaner."

    If you know anything about (1) engineers, and (2) guys in general, you know what happened: The purpose of the charcoal- lighting shifted from cooking hamburgers to seeing how fast they could light the charcoal.

    From the vacuum cleaner, they escalated to using a propane torch, then an acetylene torch. Then Goble started using compressed pure oxygen, which caused the charcoal to burn much faster, because as you recall from chemistry cl***, fire is essentially the rapid combination of oxygen with the cosine to form the Tigris and Euphrates rivers (or something along those lines).

    By this point Goble was getting pretty good times. But in the world of compe***ive charcoal-lighting, "pretty good" does not cut the mustard. Thus Goble hit upon the idea of using -- get ready -- liquid oxygen. This is the form of oxygen used in rocket engines; it's 295 degrees below zero and 600 times as dense as regular oxygen. In terms of releasing energy, pouring liquid oxygen on charcoal is the equivalent of throwing a live squirrel into a room containing 50 million Labrador retrievers. On Goble's World Wide Web page (the address is http:// ghg.ecn.purdue.edu/) you can see actual photographs and a video of Goble using a bucket attached to a 10-foot long wooden handle to dump three gallons of liquid oxygen (Not Sold In Stores) onto a grill containing 60 pounds of charcoal and a lit cigarette for ignition. What follows is the most impressive charcoal-lighting I have ever seen, featuring a large fireball that, according to Goble, reached 10,000 degrees Fahrenheit. The charcoal was ready for cooking in -- this has to be a world record -- three seconds.

    There's also a photo of what happened when Goble used the same technique on a flimsy little $2.88 discount-store grill. All that's left is a circle of charcoal with a few shreds of metal in it.

    "Basically, the grill vaporized, " said Goble. "We were thinking of returning it to the store for a refund."
