Default Octane Boosters

Interesting Thread going here ya think? MY 2 centavoes with some questions.

Dave Maybury/Jack Zupan- Chemistry is 100% correct.(I think) One thing you guys touched on but didn't expand on was what they are trying to get out of gas. Sulfur, benzenes, cynides , and other trace metals come to mine along with certain aromatics. The sulfur will have big time consequences in the near future I'm reading in the trades. I like the way this tread has got past the wives tales about toluene to. Now, as for the the pros and cons of toluene, have we sort of reached a standstill ?

Dave Samson- Before I move to your coast are you sure that 98 octane gas sold down there is 98 octane using the same method of rating used here in the states? Just curious.

Jam1775-The advice you got on previous replys was fairly sound.
Octane does slow down the burn in your engine. In your case you should stay with better gas though, not for the performance gains, but for the additives that help your engines starting, etc.
As for the performance piece and octane, the performance guys in the other places are correct and this is the dope: The more ignition advance you run in your engine the more power it makes, up to a point then power goes down with even more advance. Increasing octane lets you increase the amount of ignition advance you can run. Both statments above are controled/regulated by your engines static compression. Very few folks I have found, optimise their gas/ignition to get the most power out of their engines. In the real world compromises are made because of the rotten gas thats out there and this is why it's largely a performance thing.

So, does a 30% toluene mix screw up fuel injectors? This might be a question for performance injection folks, right? I know for a fact it does not bother carbed applications per a thread here on Clubcobra called "secondary fuel delivery systems(long)" I entered a long time ago. You see, I started foolin with this stuff back in 1976 and even then toluene won the war. My next step, I want to try oxygen rich fuel mixes(alcohols and nitromethanes)together with toluene mixes on a secondary fuel injection system
for drag racing next season. Should be fun!

Wow-Dave replied before I could edit out my rotton' spellin'!
