When regular fuel is spiked with octane booster you can smell it in the exhaust around the car. Is there any additive that you know of that is odourless?

why not just but racing fuel? it is more consistont then measuringout fuel additive and guessing how much fuel that you have in the cell

if every thing is under control your not fast enough

we are not allowed to use racing fuel. The rule says it must be regular unleaded fuel with no additives.

years ago we used moth balls to creat methane in the fuel but i cant say that i remember it smelling

1 moth ball to every 5 gallons

Let me see if i comprehend this. I bet that someone racer knows is HIMSELF? lol. Disrespect nah pure compliment that you can get away with it LOL.

Just out of curiosity I know some tracks test the fuels, would they be able to detect the booster in the fuel, moth balls I would think they could detect. Eddie

I believe I got this off of one of the searches on here about a year or so ago.
7:1 comp ratio-89 octane
8:1 comp ratio-91 octane
9:1 comp ratio-94 octane
10:1 comp ratio-98 octane
11:1 comp ratio-104 octane
12:1 comp ratio-110 octane
13:1 comp ratio-113 octane
Hope this might be of some use, I know that to much octane in a lower compression motor wont help it any. Eddie

Great Info! Thanks. We are about 9 to 1.

VP makes C-10, a racing unleaded of 100 octane. You could mix that 50/50 with unleaded and have a decent fuel. At 9 to 1 though you're probably wasting your time. Quality unleaded or premiuum unleaded should be fine.

Good luck,

Octane requirements for any engine will vary due to burn charteristics in the heads and pistons and any hotspots on the compressed cylinder/head package. We have run 12.5:1 on 93 octane at 200 degrees and no problems. I have also seen 10:1 motors pinging on race fuel.
A NOTE ON OCTANE ONLY USE WHAT YOUR ENGINE NEEDS!! HIGHER OCTANE IS HARDER TO IGNITE!
A friend has an offshore power boat and was in a fun run from Tampa to Sarasota and back. On the trip down the ran the racing fuel they always used. When they got down to the turn around and the only fuel they could get was 93 octane pump fuel at a marina. On the way back they ran into a head wind all of the way and averaged 7 Miles per hour faster. They later confirmed this on a second test run and have never used racing fuel again.

for the note we have to run a class with a max comp. 9.3 to 1 we are at 9.2 we use streight prem. unleaded from caseys. a lot of the detonation issue revolves around chamber & hot spots , & how much you are luging your motor .for example when we go to some smaller tracks i will go 1 to 4 with aa sonoco purple, you can not smell it & i have been tested & passed . but you can make more power with less octane if can keep it ot of deonation

one more thing that i forgot is: IF you can run ethanol DO IT people forget that ethanol has oxygen in the more oxygen you have in your fuel the more fuel you can put to your motor thus more horsepower to a point Stock Car racing magazine did a study on this the best mixture they came up with for a 9to1 motor was a 80/20 mix of ethanol wich would be 20% ethanol and 80% of 91 octane. Now to get your 20% of ethanol you have to go somewhere that has the E85 ethanol and be careful on your jet settings you can bure too lean.

kart racers used to fool tech with polypropline. (sp?) Not petrolem based so wont cloud the water. Very volitile though from what I hear.

I would be iffy about trying it in a race car.

I honestly wouldn't even bother with octane boost... One point they talk about is not the same as one point of octane... The ****'s about pointless from my experience with it.

Heck you can just add some flower smelling fuel cent and just act like your just wanting to make the track smell pretty! might get some looks about that

Propline will run in a street stock car, as long as its mixed properly it won't detinate and it doesn't smell, but it won't fool a fuel gauge. I don't know the mixture you will have to find some1 else for that. In a go kart which we also race you can run it with a pretty heavy mixture. It will shoot a slightly different blue flame though.

Some info on mothballs in a gas tank
I was thinking about giving it a try so I did some research and here is the best explanation I could find
and mothballs cost darn near as much race feul

I have been told that
adding seven or eight
naphthalene mothballs to a tank
of gasoline increases the octane.
Is this true? If it is true, what will
it do to the engine of the vehicle?
-- Donald

Ray: That's an excellent question, Donald. This "mothball" story has
been around as long as we have. So immediately upon receiving your
letter, we called in the illustrious Dr. Jim Davis, Ph.D., director of the
chemistry labs here at Car Talk Plaza, to try to get a definitive answer.
And Jim said he'd get right on it.

Tom: Two months later, he called us and apologized for the delay,
which he said was unavoidable due to a two-month-long faculty
meeting that had just ended at Harvard, where he moonlights.

Ray: Anyway, after several months of study, and the complete
depletion of an otherwise useful NIH grant, Jim has concluded that this
mothball story is basically a bunch of horse pie.

Tom: There are several different types of mothballs on the market,
none of which, to his knowledge, do anything to improve the
performance of gasoline. They WILL burn, so you will get some
power out of them. But since mothballs are more expensive than
gasoline, this is not a very economical way to get to work, Donald.

Ray: If there were some magical performance-enhancing mothball,
Jim says, don't you think Exxon and Mobil would be selling it to us as
an expensive gasoline additive i.e. "Mobil Super ... Now with
Mothballs!"

Tom: The kind of mothball you mention, Donald, is made of
"naphthalene" which is a hydrocarbon, like gasoline. For those
chemical engineers reading today, it's C10H8, and it looks like two
benzene rings fused together. Jim says that benzene makes a very
smoky fire when burned, so his guess is that naphthalene would make
a lousy gasoline. On the other hand, he says, since it's just carbon and
hydrogen (like gasoline) naphthalene probably wouldn't do any harm to
the engine either.

Ray: Another type of mothball which COULD potentially hurt things
is made of dichlorobenzene. That won't improve your car's
performance either, but since it throws chlorine into the mix, it can
produce HCl as a byproduct when burned.

Tom: For those of you who don't remember your high school
chemistry, HCl is hydrochloric acid, the stuff that burns through almost
anything it touches. And pumping HCl through your engine and
exhaust system is probably not very good for its longevity, Donald.

Ray: Not to mention what it does to a) the people who happen to be
breathing anywhere near the end of that exhaust system, b) your
catalytic converter, and c) your manufacturer's warranty.

Tom: So, based upon Jim's
research, we feel confident in
summarily dismissing the notion
that adding mothballs to your gas
tank does anything to improve
performance.

Ray: The only thing Jim will guarantee is that, if you put mothballs in
your gas tank, any sweaters you store in there will come out without
moth holes in them.


So sorry to step on your balls who ever mentioned the mothball theory
