What do you think of this guys !? Really works !? Dangerous !?


Sorry, had to translate it on Google...


"The nitromethane is applied as combustible in race cars, rockets and aircrafts.
The oxygen contained in the nitromethane allows a lesser air burning (oxygen) atmospheric in comparison with other hydrocarbons with the gasoline.
To burn 1 kg of gasoline 14.6 kg of air (oxygen) are necessary, 1 kg of nitromethane need only 1.7 kg, a time that each cycle of the engine can
contain only one limited amount of air, can burn 8.7 times nitromethane than the gasoline (the level of the sea).

However, the set free energy for the nitromethane is lesser, while the burning of the gasoline liberates between 42 and 44 million Joules for kilo (MJ/kg),
the nitromethane liberates 11.3 MJ/kg. From these data, one concludes that the nitromethane generates 2.3 times approximately more than the power of the
gasoline when combined in the certain ratio with atmospheric air. The nitromethane (CH3NO2) is miscible in alcohol, methanol, that are methylic alcohol,
gasoline, among others, being usually combined with the two first ones. In general 10% are applied in 5% mixtures, for engines of high tax of compression
or with turbo, and of up to 40% for engines of low tax of compression and natural aspiration. Had to the power increase, it is recommended reinforcement
in the engine to prevent reduction of the useful life. The profit of power with the nitromethane happens of the presence of oxygen in its molecule,
causing a effect of similar overfeeding to the one of nitrous oxide (NO2).

This oxygen is used in the fuel burning, allowing the injection of bigger amount of fuel.

Part of the molecule (CH3) also is combustible and the N does not participate of the burning, forming N2.

The profit in the use of the nitromethane is not accurately for increase of the calorific power, but for allowing the injection of more combustible
for one same air mass, since it loads part of the oxygen for the burning in its proper molecule.

Mixtures with alcohol, methanol and nitromethane attack components not proteges, as injector peaks and other parts citizens the corrosion.
This to a large extent happens for these fuels to contain oxygen in its molecules. Alcohol and methanol, in turn, increase the antiknock index (IAD),
that it indicates the trend to the detonation of the fuel, in the direct ratio of the mixture.
The gasoline they mixed gain octanagem.

The components of the engine and its regulation must be adjusted for the use of the new mixture when this will be being used.



The literature found in the site is only for informal consultation, the Nitrometano ProŽ Magma is vendido for fuel purpose, as additive,
we do not make responsible in them for no damage or bad use of the product. Before preparing its fuel a specialist always consults,
takes all the necessary precautions for the manuscript."

Actually nitro burning top fuel and funny cars have something north of 6000 horsepower. It does not mix well with gasoline and you had better know what you are doing or you will ruin a lot of stuff finding out.

I agree Nitro explodes.My buddy had a nitro Harley drag bike.You should ask him about the 15K motor that was brand new.Fired and stalled.Didnt clear the cylinders and cranked it.One guy was almost killed by a big chunk of the motor that flew by his head and embedded in the wall.Rocky

The compound nitrogen dioxide , with a chemical formula of NO 2 The nitrite ion , links to the central carbon in CH3 to form nitromethane.

Get yourself a Procharged Outlaw 10.5 car and dig right in.

Nitromethane,Nitrobenzene, nor Hydrazine. I have never used any of these in my race cars,(especially running against the World of Outlaws) nor has any member of my family, however there may or may not be close facsimiles of these on my shelf. This is not a legal document and will not hold up in a court of law or any tribunal interrogations, illegal or otherwise? As usual this message will self destruct in a day or two. Hemigregg, tell us a little about these.

Goes without saying! However I did see a woman (looked just like my Mom) make a run in a Fuel Altered in 1965, my Dad was testing some new elixer, I'm sure it must have been legal.

yep. it is a learning curve...

one of my first mistakes was to assume the percentage when at a race. weather moved i n (front) dropping temps enough that i lost around 4 full percentage points on the load.

made a differance that could be heard and felt when the bike was running...learned the hard way as i lost that round.

Ok,

and about a safe percentage to mix with alky... or there´s no safe....

yea. you need to get the specific gravities and the equipment to measure it. the percentage will always change. hence the need to measure and mix just before the pour

I've always wanted to play w/ nitromethane but never had the $$$.

I'd wanted to play w/ hydrazine. Until I did some research about how dangerous it is - just to handle and store. That's before you even get it in the car.

It makes that hexavalent chromium from Erin Brockovich look like vitamin water or something.

(gotta' watch that movie again... Julia Roberts... mmmm...)

Seduce the attractive, and charm the rest. ****** 489 C.I.D., roller cam, aftermarket heads, tunnel ram, stock '54 Dodge rear axle assembly: which of these doesn't belong?
