Toluene as an Octane Booster - any experience?

[986FortyEight]

I was browsing renntech and came across a post from a 996 carrera owner about using higher octane fuels for his car. he had a link to a somewhat lengthy article about using Toluene as an Octane booster. According to the author's testimony the results were quite significant.

Has anyone here tried boosting the octane of your fuel using Toluene? Any other additive?

here is a link to the post:

I am eager to hear from everyone.

Anyone who understands the principles behind an octane rating will tell you that there's absolutely no need to increase a fuel's octane rating if the car's not designed to take advantage of it. The spark timing is set for premium fuel, raising the knock rating further cannot change spark advance any further.

Now adding a fuel with higher heating value can be a benefit, but with greater power adds greater wear and reduced longevity, not to mention compatibility issues between the fuel and fuel system components. In addition, there's fuel metering values and after treatment equiptment to worry about. I'd just stick with the stuff from the pump.

Thanks blue.

I made a search on the forum for Octane and came across this excellent thread from 2005:

93 or 100 octane

I do understand the concept of octane rating as a relation to compression ratio VS spontaneous ignition and the goal of raising the octane rating to prevent knocking.

Although I am still a bit confuse on the question of calorific value of Toluene VS gasoline and therefore the ability to raise the amount of energy generated through the explosion process.

interesting stuff for sure...

has no use on its own

Only needed when you combine it with one, or ultimo a combination of:
- raised compression
- more advanced ignition timing
- forced induction (super charger/compressor or turbo)

Well actually, a combination of raised compression and force induction is not recommended on m96 engines

lol! I've come to realize that reading about the various types of failures and also the work Jake is doing.

Thanks Mark! (or should I say "Bedankt" ?)

'Bedankt' is ook goed. Nederlands is moeilijk maar met een beetje proberen lukt het wel
