Hydrogen Peroxide

For motor fuels - price is paramount.  Even the lousiest grade of lab
chemicals is better than needed for fuel grade.  If you get a price
break over other sources - go for it.

Be extremely careful over H2O2.  You know that I do not believe in the
MSDS lies and am well aware of the level of risks of most fuel
components.  Be very careful of H2O2.

It will above a certain concentration dissolve your skin to the bone. It
has nasty uncertainty with regards to combustion and will auto ignite in
moderate concentrations depending on what it comes in contact with.

As a rule, H2O2 above the 15% beauty shop solution is best left for
rocket fuel applications done far away and on someone else's nickel.

A 2 or 4 stroke loves nitromethane sometimes.  Model fuel is blended
with a lubricant, methanal and the nitromethane.  The octane in the
alcohol tends to cancel out the lack of it in the nitromethane.  Most
engines can probably run on any commercial mixture without detonation.
Toluene has about the same octane as methanal, but about double or more
the fuel energy.  Adding toluene will tend to increase the octane of the
blend and reduce the fuel consumption or conversely, increase the energy
output.  

Unlimited benzine ring aromatic's for the allies defecated all over the
power advantages of super-complex jew burner injection systems that
tried to make piss burn well in an engine.  So much for the superhero's.

Add enough toluene to eliminate detontantion then add more nitro to
bring it back then loop to beginning and repeat until satisfactory
performance or the engine self destructs.

When you start blending toluene with nitro and alcohol, you would
probably want between at least 5 - 10% acetone added to the blend to
reduce phase separation ( where the water separates from the fuel or the
different fuels separate from each other in solution ).  Acetone octane
is nearly that of the methanal - well above gasoline - and with an
extremely low flash point, starts combustion much quicker than alcohol
or nitromethane and burns way faster.

If you are truly wicked and evil, you might consider blending Cetane
Improver with the toluene and nitro.  Most fuel enhancements such as
alcohol, nitromethane and to a lesser extent toluene, require advancing
the spark significantly to develop maximum power.  If you suddenly drop
some or all of the kickapoo joy juice, you are left with way too much
advance and can detonate the engine out of existence before even an
automatic fast acting control system can help you.  Over running a
piston with nitro is a classic example of it only takes one burp.

In leu of advancing the spark, leave the spark for the baseline fuel and
increase the speed of combustion of the joy juice.  Ignore the doom
sayer about Cetane improver's reducing octane.  We are interested in
them increasing the speed of combustion - like they do with respect to
diesel fuel.  The faster the combustion, the less lead you need at any
speed.  You are starting with a blend of about 120 octane methanol,
adding some non burning synthetic lubricant, some octane reducing power
enhancing nitromethane with an incredible heat of vaporization at stoic
from both 2.5 times that of gasoline plus burning 8 times as much per
pound of air, some blending acetone - again around 120 octane, and a
combination of toluene and cetane improver - with toluene/xylene at
least 120 octane and the cetane dropping it somewhat and speeding it up.

I would blend the joy juice, the separately blend cetane/toluene in
33/66 mixture to start.  Add as needed to model boat fuel - with
whatever amount of acetone but at least 10% to insure blending and no
phase separation.  First pass - in a glass jar not exposed to continuous
light and most definitely not sunlight and let it sit for two weeks or
more.  Looking for different layers of fuel substances.  Layers - add a
splash or more of acetone.

For Daves test motor,  same plan - add model boat fuel for power, add
some acetone, toluene and Cetane improver and tune for minimal knock and
maximum power.  Instead of adding spark, add Cetane Improver.

For example, Acetic acid does not blend well with certain fluids and
tends to go glacial.  TBA (Tri butyl Acetate) decomposes to butadiene
and acetic acid under combustion.  Play with as needed.

Potassium Nitrate ( Saltpeter ) and potassium permanganate tend to
dissolve well or go into solution with many of these chemicals.  Adding
a bunch increases the oxygen level of the joy juice.

But I am rambling.  Start with the model fuel and work from their.
Nitro can get very expensive very fast depending on the taxing
authorities.
