I've been to Home Depot and Lowes. Who carries toluene at a reasonable price?
Q: How much toluene should I use per tank of gas?
A: Octane ratings can be very easily calculated by simple averaging. For example, the tank of an Audi A4 1.8TQ is 15.6 gallons. Filling it with 14.6 gallons of 92 octane and 1 gallon of toluene (114 octane) will yield a fuel mix of:
(14.6 * 92) + (1 * 114) / 15.6 = 93.4
The Audi A4 1.8T is a good example of a car that has very high octane needs if it has been modified to produce more turbo boost. The base compression ratio of this car is a very high 9.5:1 and when an additional 1 bar (14.7 psi) of turbo boost is applied on top of it, the resulting effective compression ratio is way beyond what 92 or 93 octane fuel can ever hope to cope with. Most modified 1.8Ts running without octane enhancement are running with severely retarded ignition timing and boost.
God, I never tried toluene, but why would the "off the shelf stuff" be different? If I remember my chemical engineering, toluene is just methylbenzene, a benzene ring with a methyl group.God said:You guys that are using Toulene please be careful. The off the shelf stuff is NOT the same as the industrial grade. The off the shelf stuff does not raise octane enough for it to matter. Maybe a point or two on a tank which to me seems pointless. Better to go buy C12 or C16 fuel somewhere nearby. Not much more expensive and works a hell of a lot better.
Regarding the "explosive thing", I have a gallon of gasoline in a gas can for my lawnmower in my garage. It is explosive.SD_GR said:I'd be a lot happier going some place and buying fuel that's simply pumped into the car than having stuff like toluene in large quantities around. Setting the whole explosive thing aside, since decent containers and common sense are, um, common, toluene is a carcinogen and a teratogen.
There are cases of children born to women exposed to toluene vapors throughout their pregnancy that had CNS problems, microcephaly (literally, "small head"), limb abnormalities, cranial abnormalities, and developmental problems.
Got a headache from the stuff? Got aspirin? People did work almost 20 years ago showing both maternal and embryonic toxicity increase when toluene is inhaled and aspirin taken orally.
Now, I'm the first to admit a good write-up can make even common table salt or spring water seem like the most toxic substance known to man, but there are dozens of papers out there on this and I only remember a couple off hand, and I promise I'm not overstating stuff. I just don't like organic solvents, never been a fan.
Yes, our cars are tuned for pump gas, but some of us have changed the tune. I don't know where race gas is available for sale.SD_GR said:US gasoline differs from EU super-unleaded, and our cars are tuned accordingly. A good tank of race gas when "needed" is preferable IMO to running about sourcing fairly rude chemicals and then dealing with their storage. If you must buy the stuff, get chemical grade from a lab supplier - at least you'll get your money's worth (and it'll be cheaper than analytical grade or whatever term your vendor uses). If you want to save $ and go from hardware stores, it might be worth it to contact the manufacturer of the paint thinner or whatever you're eyeballing and getting hold of the MSDS - thay can fax or snail mail it to you and it'll list composition so you'll be able to guesstimate purity, and at least know what you're burning.
I don't think it's worth the hassle, but that's me. I vote for turning the boost down to stock, working on the fueling curve for max safe torque, and spending the money on suspension or a weekend trip to catch a local rally stage or two - but that's just IMO.
My point exactly. Were I to purchase a container labeled "toluene", that's exactly what I'd expect to find in that container. As far as I know, there are no variations of toluene. Either the compound is toluene or it isn't.Regarding purity, I haven't used toluene but I would assume that if I buy a gallon of toluene that the liquid in the container is toluene. If it contains something else, wouldn't it be listed on the container?
