that **** is bad for your motor, go to gruppe-s or ATP and buy race gas...its ~ the same even if u mix it

 

or go to the 76 gas station on the corner of Almaden Expwy. and Foxworthy.....they have 100 octane at the pump ~ $4.29/gal.

-Ted

 

home depot has it.

 

Not in the Ebay - they do have Xylene though for $10/gallon !

Sherwin willimas will order it for you for around $5/gallon in the 5 gallon buckets - at least that's what I paid last summer.

I think Gruppe-s has race gasoline for sale - no idea on the price though. I think it is 100 or 114.

 

sorry i meant Xylene. hahah one of those lene's

 

Shermin Williams on Bascom Ave. in Campbell sells toluene in 1 or 5 gallon jugs.

Open an account with them and you can buy it for more of a discount if you plan on running it all of the time.

Toluene = 114 octane

And for future reference:

Q: Why do you think toluene is better than other types of octane boosters?

A: Several reasons:

Mindful of the evil reputation of octane boosters in general, toluene is a very safe choice because it is one of the main octane boosters used by oil companies in producing ordinary gasoline of all grades. Thus if toluene is indeed harmful to your engine as feared, your engine would have disintegrated long, long ago since ordinary pump gasoline can contain as much as 50% aromatic hydrocarbons.

Toluene is a pure hydrocarbon (C7H8). i.e. it contains only hydrogen and carbon atoms. It belongs to a particular category of hydrocarbons called aromatic hydrocarbons. Complete combustion of toluene yields CO2 and H2O. This fact ensures that the entire emission control system such as the catalyst and oxygen sensor of your car is unaffected. There are no metallic compounds (lead, magnesium etc), no nitro compounds and no oxygen atoms in toluene. It is made up of exactly the same ingredients as ordinary gasoline. In fact it is one of the main ingredients of gasoline.
Toluene has a RON octane rating of 121 and a MON rating of 107, leading to a (R+M)/2 rating of 114. (R+M)/2 is how ordinary fuels are rated in the US. Note that toluene has a sensitivity rating of 121-107=14. This compares favorably with alcohols which have sensitivities in the 20-30 range. The more sensitive a fuel is the more its performance degrades under load. Toluene's low sensitivity means that it is an excellent fuel for a heavily loaded engine.

Toluene is denser than ordinary gasoline (0.87 g/mL vs. 0.72-0.74) and contains more energy per unit volume. Thus combustion of toluene leads to more energy being liberated and thus more power generated. This is in contrast to oxygenated octane boosters like ethanol or MTBE which contain less energy per unit volume compared to gasoline. The higher heating value of toluene also means that the exhaust gases contain more kinetic energy, which in turn means that there is more energy to drive turbocharger vanes. In practical terms this is experienced as a faster onset of turbo boost.

Chevron's published composition of 100 octane aviation fuel shows that toluene comprises up to 14% alone and is the predominant aromatic hydrocarbon. Unfortunately composition specifications for automotive gasoline is harder to pin down due to constantly changing requirements.

thanks MR. Wizzard!!! lol

what up KD?? Where you been??

-freddie

 

hey Kurley......So does that mean that your engine is gonna run at a hotter temperature than normal? Making your EGT read hotter as well?

-Ted

 

actually higher octane fuel is "colder burning"... so theoretically your EGTs should be lower.

 

Hanging out on the same forums, just not posting here as much. Also been learning a lot about the SRT-4, but rarely ever on SRTforums.


Ted, read up on "How Stuff Works", and I don't mean that in a mean way.

The octane rating of gasoline tells you how much the fuel can be compressed before it spontaneously ignites. When gas ignites by compression rather than because of the spark from the spark plug, it causes knocking in the engine. Knocking can damage an engine, so it is not something you want to have happening. Lower-octane gas (like "regular" 87-octane gasoline) can handle the least amount of compression before igniting.

Remember the whole reason for using toluene in the first place is to fight detonation
or knock. If your car is running fine and you have no audible knock, you should not have any need to run toluene or any higher octane fuel. It is not a magical power adder on its own unless you have the ability to tune for it.

Also remember that detonation is caused by excessive heat and pressure inside the combustion chamber which ignites during compression. This also happens at the same time the spark plug ignites, causing massive pressure rise in the cylinder. Higher octane gas and/or toluene can help prevent the combustion process from igniting to early, keeping cylinder pressures and temps down.

Correct me if I am wrong, but I thought that the wrx ecu (even when stock) could sense a higher octane up to 93 or 95, and advance timing a bit or do some other stuff to increase performance. I know that by putting 91 in my car I can't possibly be making as much power as on a similar car on the east coast where they have 93 octane.
I keep telling myself that I need to go down to the hardware store and get me some toulene, but I never do, and dammit its about time I do.

 

Toulene is the stuff you use to soften up your tires in preparation for some track time...I used to sponge it on my shifter kart tires the night before a race and wrap them in saran wrap...it is also known as Track Claw....you can get 104 octane race fuel at Infineon for about $4.50 a gallon...beware...Toulene is a known cancer causing chemical as well.

 

OSHA doesn't list it as a cacinogen.

IARC (international agency for research on cancer):
Group 3 carcinogen = not a human carcinogen

This means it is just corrosive (ie breathing and skin danger).

There are a couple of things to consider:

1. Quality of the toulene - lots of chemicals have extra stuff in them not listed on the label, such as lead. You will probably want pure toulene.

2. Toulene is a solvent - you will probably want to add a small ammount of lubricant to the mix.

Good Luck.
