Actually, nitromethane is a common fuel additive. Most glow fuels sold in
the US have some in it. At low percentages, 5% to 10% it improves idling,
higher percentages provide much more power.
The additive that Lev Muznik is asking about, Amyl Nitrate, is commonly
used in model diesel engines. Try Davis Diesel as a source.

Automobile parts stores have additives called "Cetane Booster" which has
the ingredients you are looking for. "Cetane" relates to Diesel, as
"Octane" relates to Gasoline. You may have to add up to 10% of the
"additive" because it is not pure amyl nitrate, but rather several
ignition enhancers suspended in a light oil.
Trent
It is not at all suspicious that a diesel engine manufacturer would
reccommend amyl nitrate. It is a very common c-tane enhancer used by
many suppliers of diesel fuel. It is sold as a product known as powermaster
405 ( im not entirely sure of the number; it could be 205) and is available
in some truck stops. It is also available from good old Red Max in 1 gallon
quantities, for I believe about 30 bucks a gallon. Maybe a little cheaper.
When I called them I priced both ether and amyl nitrate and I may have the
prices mixed up. Better yet why not just purchase a commercially available
model diesel fuel such as Red Max or Davis Diesel. It already has amyl nitrate
in it, and should run your engine fine.
I don't mean to be presumptious reccommending only American suppliers. I am
just only familiar with them. With the popularity of diesels in Europe, I
can't imagine not being able to buy it from many suppliers all over the
world.
They have been undergoing something of a resurgence lately with engines
from Irvine and others - most of the old problems of poor throttle
response and vibration seem to have been overcome in the new engines. And
the fuel smells good, too...

Here you are confusing amyl nitrate with amyl nitrite, with an 'i'.
The latter is the poisonous drug, while amyl nitrate is relatively
harmless.

Amyl nitrate is the classical additive for diesel fuel, absolutely
essential for high rpm diesel running. The addition of to the fuel 3%
poses no hazard.
Many other organic nitrates (and nitrites, although they should be
avoided.) are also useful: Iso-propyl nitrate, hexyl nitrate and so on.
There is a commercial product from Ethyl Corp. "Diesel Ignition
Improver", which is a mixture of many nitrates. If you want less than a
barrel :-), you can get it from Nelson Competition Engines. (I'm afraid
I haven't the address right now.)

Not so. Learn some about diesel engines.
A typical fuel for FAI Control Line Team Race, where .15 size diesels
are used at around 25,000 RPM is: Castor oil 8%, Diethyl Ether 35%, Amyl
Nitrate or DII 2%, remainder Kerosene.
The Nitrate works as an igniter and combustion catalyst, allowing high
RPM operation without a compression setting high enough to damage the
engine.

This is probably the substance I once bought from Davis Diesel in
the USA. If I remember correctly it was called Cetane Booster.
I used this as a fuel additive when I was experimenting with
a diesel conversion head from Davis about 10 years ago.

I seem to recall playing around with toluene, heptane and nitropropane
in my youthful attempts to extract more power from my diesel engines.
I expect that these are now considered carcinogenic and illegal by now.

You have not made a mistake. Amyl Nitrate was routinely used as an
ignition improver for model diesel engines for many years. It is now
virtually unobtainable, and if available, no doubt the price would not
bear thinking about. Some form of ignition improver is necessary to
get the best out of any Diesel engine.
Chemicals that you may be able to get that can do the job are:
Amyl nitrite
Iso propyl nitrate
Hexyl nitrate
Stuff called by the generic name `DII' (Diesel Ignition Improver)
It can be bought from the engine manufacturer Henry Nelson - check
one of the current model magazines for the address of Nelson engines
as I dont have one by me at present. For a while there was also an
additive for truck diesels (full size) called `anti knock', it was
marketed by Wynns products. You might be able to locate some of that
but although I haven't used it myself, I hear that you may need 4% to 5%
to have any affect. The best option is to contact Henry Nelson.
Percentages for use will usually vary between 1% and 3%.

Nothing to be suspicious of, Don.
Yes, Amyl nitrate is (was) used in small percentages in diesel model
engines. However, I think the problem drug is amyl nitrite. (Goran
Olsson can set this straight.)
A suitable relplacement is "Diesel Ignition Improver" manufactured
by the Ethyl corporation. The typical source in this country is
Henry Nelson. 1-1/2 to 2% is the typical amount.

You're forgetting one major class of engine - the model diesel. It is
indeed used as an anti-detonation additive in model diesel fuel. The
Oliver Tiger is indeed a diesel.

No, they add a tiny percentage of SO2 to the N2O to make it
unsniffable. Theres been quite a bit of talk about it on
rec.models.rockets.

The Oliver Tiger was the "Nelson" of the pre-1976 British Combat
scene. Very rare. I think they were hand-made, or at least
hand-fitted.
2) This stuff was not controlled a few years back (but I suspect it
should have been).
3) People are going to get off on all sorts of odd things - even model
glue (the toluene in old solvent glues was a favorite, I believe).
Whatever a persons' opinion is of these practises its inappropriate to
try to supress knowledge 'just in case'. "Does it really matter?"
4) The most reliable source of nitrous oxide for the sniffing brigade
used to be the propellant in aerosol dairy products - cream toppings and
the like. Burying one's face in a pile of cream in the hope you get a
whiff of N2O certainly plums new depths in grossness, but people have
been known to do it!
(PS The author, while an avid observer 'in the old days' never quite got
that low........)
You could also try Davis Diesel developments or Nelson Competition
Engines as they both have lots of experience in diesels.

^O^
Actually, no.. the way they did it was to buy the little bulbs that
contained the N2O. These bulbs were like the ones you use in BB guns,
or the "Sparkletts" bulbs used in CO2 Power (which were really for
making home-made soda). The bigger confectioners, bakeries, etc. had
machines that took the bulbs and made whipped cream.
The N2O for automotive use has been denatured with SO2 (which makes it
unsniffable).

I've heard that the main problems with the old motors was simply
because they were _old_ motors - the designs dated back to god knows
when...
Apply modern schnuerle porting, tapered sleeves, ABC piston/liners,
etc. to diesels and they run and throttle very well indeed, more like
a modern glow. The newer ones can also run well at high RPM - the old
ones supposedly liked big props and low RPMs.
But the fuel smelling good?? One of the main complaints about diesels
was that they STANK. On the other hand, the exhaust supposedly does
smell just like a jet...
