So I was going to the store the other day for some nice paint stripper. And I saw this big canister of 100% Xylene.
For some reason it reminded me of my Supercharged 4.6 liter V-8 running 500hp on pump gas.
Some times I'll tweak the tune to the ragged edge with the timing and A/f ratio before going to the track. With the hypereutetic pistons, detonation is suicide, but I still want to beat that corvette with my 2 ton sleeper.
For a little insurance, and a little power if it's running lean on a cold day, it's usually a good idea to raise the octane of the fuel with this type of induction combination (hot roots blower).
I have no idea what the difference is between the octane ratings you read at a gas pump, or ratings labeled as "fuel octane", or if you visit this site,
They site other terms for octane ratings, "motor octane", "Research Octane", on some of the fuels listed at that link they also site "density", and "specific gravity" at different temperatures for the fuels.
The signifigance, and the differences I have no idea.
I appreciate any insight there, or a good resource if anybody knows of one.
If you look at the ingredients of Octane boosters, the actual fuel is either Tolene (sp?), or Xylene, I think the rest is lubricant, cleaner, filler etc.
Very little actual fuel in these boosters, they advertise 1-3 points boost in octane which means at most you go from 91 octane to 91.3 octane, NOT 94 octane.
I'm a big fan of Mobil as their fuel seems to hold it's octane well over time. As an additive, I plan to add pure Xylene which I believe is about 120 octane. probably 60/40. Putting it around 102 octane or higher. I assume there is a reason for the lubricant in the octane booster?
Would no fuel, and pure xylene damage components in my induction / fuel / exhaust systems?
Injectors? fuel lines? 02 sensors? cats?.... well cats are gone
Well thanks for any tips on deciphering fuel spec's, and your thoughts on xylene.
On a side note:
I also have a naturally aspirated car, that I may raise the compression on and run the tune to the ragget edge to squeeze the potential out of the combo as far as I can, so I'm complating running one of the Vp fuels, supposedly they get get real results from this fuel, however it's leaded, and I'm afraid to run that with 02 sensors. They are kind of vague, I wonder if it has oxygen content, I wonder how the specific gravity plays into fuel performance.

Produces very significant horsepower and torque over all other fuels. Impressive results in normally aspirated compression ratios, from 9:1 to 17:1, drag race or oval track qualifying applications.
• Color: Yellow
• Leaded
• Motor Octane: 98.6
• Specific Gravity: .682 at 60° F "

This is just a hobbie for me, I like to try to take an underdog combination, and realize the maximum possible capability of it, many times you get some impressive and suprising results. Even if I have to cheat with some fuel, heh.
Thanks in advance!
