Meth injection for N/A cars is proven.

It lowers IATs in 90-100 dgree weather in addition to massive detonation suppression.

I did not know toulene was used in gasoline, i know it is used in avgas though. I'm sure it will increase octane, but there is a chance that it is like ethanol, if you use too much, your ecu will have to be tuned for it.

True, the stoichiometric A/F ratio for toluene is 11.5:1.

http://www.powerchipgroup.com/articles/PET0605.pdf

For those wanting to know how toluene increases octane:

http://www.coe.pku.edu.cn/tpic/2012102671228353.pdf

Keep in mind when they are talking about ignition delay, they are not talking about spark timing. When talking about fuels and combustion, ignition delay refers to the time between when the temperature is sufficient for ignition and when the actual flame starts. There are many pre-flame reactions that occur and toluene causes more radicals to form before actual ignition happens thus increasing ignition delay. MMT, as used in octane boosters with a 2-3 octane number increase, introduces metallic chemical compounds into the pre-flame reactions that increases the number of radicals formed thus increasing the ignition delay. TEL as used in leaded gas does the same thing. A small amount of MMT/TEL can increase the number of radicals substantially which gives an initial increase in octane. As concentrations of MMT/TEL increase, the increase in the number of radicals formed decreases exponentially until a point is reached at which very little affect occurs...it doesn't take much MMT or TEL to reach the point of zero returns. That's why the blending chart on the Torco website is BS as well as their claims of 10-11 octane number increase. The science disputes their claims but as PT Barnum said, there's a fool born every minute.

Subscribed...& a question. As I understand it, my '12 LS3 runs best on 93 octane, but we only get 91 in my area of CA. I also understand the ECM/PCM pulls timing @ 91, but it sounds like 93-ish octane is possible with a 16oz can of octane boost in a full tank of gas? Our local autoparts place sells NOS brand octane boost, but I've not tried it yet. They do sell race gas from the pump up at Laguna Seca which is obviously preferred for hpde's.

It's been seven years since we had the discussion about Torco in the thread that was referenced.

I still run Torco in my C5, and have been running it in my C6 since late 07. I stand by the #s I stated seven years ago, although I have another source from a years or so ago ( Jim Bell and his buddies at Chevron) they saw closer to 7 points.

In 9 years, I've had one complaint. That says alot.

I was hanging out with the owner of Torco at Sema last week, he said he averages over 30 sales a day, not counting his distributors...
That's a bunch of happy customers. I can already see the responses from our friend, but he's entitled to his opinion. I just don't have any desire nor energy to try and change it, by the same token, my experience over the last 9 years with Torco will not be changed no mater how well spoken someone is...

According to glass slipper experience doesn't count, just bad theory. If you want to take the time to read thru his links you'll see that the only one that actually compares Torco to the other Octane enhancers is the thread on this Forum that mentions your "test".

Deflect, deflect, deflect...that's all you had 7 years ago and that's all you have now. Nobody ever said it doesn't work. Nobody ever said you didn't have happy customers. Stop deflecting to those points and answer the question of how many octane numbers does Torco raise 91 octane gas. In the thread 7 years ago, you actually stated several different answers and your "certified test" stated something else. Now you're saying another place has come up with a different number. And of course Torco has something completely different...you guys are all over the place. Where's their independent test results? Claims without proof are just claims...advertising 101.

Once again, the only question is how many octane numbers does Torco raise 91 octane gas? That's all this discussion is about...nobody is trying to talk trash about Torco so I don't understand why the two of you are taking this so personally. Facts are all we needed 7 years ago and that's what we're still asking for 7 years later. I find it amazing Torco can't give a factual answer to an otherwise excellent product...the BS that surrounds it is what detracts from its reputation. Is it really that bad for people to want facts? If I sold you some special water with amazing additives, wouldn't you want to know what the additives are and what exactly the "special water" will do to you? Or are you going to just take my word for it and drink the Kool-Aid.

I have a minor in internal combustion engines and in my senior year at Georgia Tech, I ran the engine lab as the teaching assistant for the internal combustion engine professor. We had a CFR engine in the lab we did a lot of research with so I am very familiar with knock, octane, and the variables associated with it. I have a good working knowledge of the chemistry involved in the combustion process, read the link in my post before this one to get an idea of the type of chemistry going on in the combustion chamber...that's if you can keep up with any of it.

BTW, a CFR engine is what determines the octane rating of a fuel, it looks like this:

If you had said Torco works for you, I wouldn't have a problem with that. If you had said you saw a 20 HP gain by using Torco, I wouldn't have a problem with that either. But Torco says 10-11 octane number increase with no proof. You parrot the 10-11 octane number increase again with no proof. Those are Torco's numbers and yours, I'm just asking for proof because those numbers don't pass the sniff test. In fact, they stink the place up really bad. If it was 4-5 octane numbers, I probably wouldn't say anything because it's close enough. If you don't know the exact number, stop making outrageous claims and stick to what you know for a fact which is it works for you and you saw a HP gain. Otherwise, you muddy the waters on an otherwise good product. I didn't make you state those claims so you can stop the attacks.

And once again, I'll give you the same answer I did seven years ago:

I mixed 10 gallons of Chevron 91 octane with 1 Quart of Torco Accelerator. I then gave a sample of that mixture to Core labs in carson. They charged $400.00 for the test, Torco and I split the cost.

The result was R+M/2 = 96.5 octane.

The thread below has a copy of the test...

And again, just like 7 years ago, there are two major problems with that test. One, it wasn't an independent test. Two, there was no baseline done to the gas minus the Torco. One other problem is you gave several different answers throughout that thread. I don't understand why you keep bringing this up because it keeps pointing to the numbers quoted by Torco as BS...it taints an otherwise good product. Show us a 100% independent certified test, not paid for by you or Torco, and we'll use that number. However, there are already tests out there of octane boosters with MMT and we already see the results...2-3 octane numbers. I keep giving you an out by saying you have a good product, I really don't understand the fixation on trying to press a technically incorrect position in the face of overwhelming evidence. Good grief, just drop the BS numbers and move on.

Thanks for enlighting me, I guess I'll go back to lugging 5 gallon jugs of 100 octane around, like I was 9 years ago.
