Re: Cheat Sheet for High Octane toulene is some serious stuff. From what I understand it is the better fuel to use than xylene even though it's octane is a tad lower.I can't remember why though.
F1 cars used to run pure toulene with enough heptane added to LOWER the octane rating to meet the octane specs.
They used to run 70psi back in the days when turbo f1 was allowed, making incredible power on that blend.Without the toulene blend it was not possible.
Toulene works better than any other booster I have ever tried.
I usually toss 2 gallons to 5 gals 93.

Re: Cheat Sheet for High Octane Ahhh! I keep going back to bookmarked sites and read about it, but never actually mixed any. Now I have a nice little spreadsheet with it. WTG.
Cheat Sheet for High Octane Little something I made up when I was turbocharged. Just get some Xylene or Toulene and your ready to go!

When you buy it at the hardware or chem. store it's usually a mixture of others chem. because it's hard to isolate it. The octane rating is for pure xylene, the one you buy i.e. the mixture is diff. & the other chem. present in the mix. may be harmful to your engine, cats, etc...
Toluene is a safer bet.

Re: Cheat Sheet for High Octane where did you get that info on zylene, i have been runing some thru my engine and if it is a bad thing i will have to switch to toluene. i have no cats so that part isn't an issure.
thanks
thanks
Re: Cheat Sheet for High Octane Hey Reckless, where did you buy your Touelene/Xylene from over here? I heard its expensive. And I cant access your cheat sheet, what is the ratio of toulene to gas? And how fast were you going through O2 sensors?

I recently read the same in an article about octane booster, I believe it's at Idaho corvette.
Anyway, I use about 15% Toluene w/ my 7lbs ATI setup in my C5, seems to take care of the occasional pigging when it's hot outside.

Re: Cheat Sheet for High Octane HP...you could buy the stuff in the paint section at Kilgo's on Sand Island. Just about any paint supply store has it. Home Depot didn't have it though. Does not harm your O2 sensors.

Re: Cheat Sheet for High Octane How does Toluene compare to say, Torco? I've used that with 7psi mixed with 91 octane and I have no KR. That stuff works great. I've run Toluene once . . . it's damn expensive here in AZ at the paint stores!!!

Re: Cheat Sheet for High Octane whether you mix Tuolene or Xylene you should not use more than 30% in your mix. Also add 2 ounces of Marvel Mystery Oil (MMO) as the additives that the gas manufacturer's add need to be added back in for proper piston ring lubrication.
We turbobuick (GN/TType) have been using this for years.
3 gallons Xylene (117 octane)
7 gallons of 92 octane
2 ounces MMO
99.5 octane! (slight savings vs. buying 100 octane from a race fuel distributor)
Or.....
3 gallons Xylene (117 octane)
7 gallons 100 octane unleaded
2 ounces MMO
105.1 octane unleaded!
