We can't see if we get problems on a longer time, next week i test on the dyno days by Biesheuvel the Cosworth engine an stronger mix, too see if we get more power. Water and Nitro colors like milk.

I come to Birmingham and give you the results, maybay we must change the normal pump for a modified one, i think we can talk at Birmingham about some technical mods :wink: .

During the dyno ill make some photo's and let them mail to yo :lol: , grtzzz
So far so good .


I will bring the teflon sealed pump to Birmingham so that you can put it on one side until the other pump develops problem. I am look forward to see the results in Birmingham.

I wonder the RC nitro contains some oil and caused the milky mix?



Today we tested 66%nitro with 34% water the results where :shock: :lol: great,grtz

Default avoiding problems

Just to avoid problems in the future, it would be very much appreciated if you guys would be very careful to specify exactly what mix your running.

I doubt very much you are actually using "66% nitro", more likely your running 66% RC fuel and 34%water, with an RC fuel that consists of methanol with about 15% nitro in it.

That would yield a mix of 34% water, 56.1% methanol, and 9.9% nitro (ignoring the castor oil that is probably in the RC fuel mix)

A little clarification about what Nitro/methanol mixes are available in your area and some effort to standardize the way we talk about the mixture percentages could save some one a very bad experience in the future.

Toward that end how about a standard notation of ;

W/M/N such that above would be 34/56.1/9.9 --- or to use round numbers, 34/56/10.

For those of us that like to experiment with mixed alcohol blends of methanol and ethanol, the same sort of system could be used.

For example a mix of 30% water, 50% methanol and 20% ethanol would be :

W/M/E = 30/50/20

To make the numbering convention universal, the rule could be ;

Water % is always the first number
Alcohols always follow the water stated in order of their molecular weight.
Ie Methanol first , ethanol second, Isopropyl third
Nitro is always last if used --- perhaps require the true nitro percentage to always be enclosed in ( )

That would make the first notation for a 66% RC fuel mix appear as:

34/56/(10)



I will start another thread on mixture notation so we don't clutter this thread up.

Default Nitromethane from RC car fuel?

An older book said Nitro should not be mixed with water and
suggested Campfer (spelling?) be used to stretch it if
detonation was feared from pure Nitro. Also suggested other
nasty non burning liquid to mix it with. But luckily it is now
proven that water can be used.
If you burn Nitromethane will that make water like gasoline does?

They may have been refering to camphor ( a ketone C10 H16 O ) It is uses as a flavoring agent, in some medical preparations, and as a plasticizer in some explosives. A liquid form is also available -- called camphor oil

The products of combustion would include water, and nitrogen compounds.
Nitromethanes chemical formula is CH3 NO2, and I believe it burns to give carbon dioxide, water and nitric acid (or other nitrogen oxides) as its combustion products. The nitric acid giving it the extremely pungent odor characteristic of a nitro burning car.

My guess is the reaction would be:

1 ( CH3-NO2 ) + 2(O2) = HNO3 + CO2 + H2O
