    WOW I missed this one.....and I love popcorn!!!!! I have a question though----Has anyone tried the Race Gas additive as asked? If I am correct the tv add also says it produces more "power" and dyno proved. Couldn't that have been done by the additive increasing octane and then they added timing?

    Hi, I'm Billy Mays and have I got some octane booster for you! Run as much timing as you want, go as lean as you want. It won't matter! It's that good.....

    How about an additive to lower octane in race gas ? My motor hits harder on pump gas than race gas, that would be nice LOLOL.

    Just got off the phone with the local speed shop. Race gas Additive when mixed to the highest concentration as indicated on the can, 7oz/ gallon will get 94 octane rated pump gas to 107! MMT as Royal Purple but just more of it. They're doing a comparison in the next couple weeks on the dyno with some type of LS set up.
    Yeah lots of high compression or boosted customers use it. Programed ign fuel to use the higher octane achieved with the additives and self detune with lower fuels , sensors etc.

    Please stay.

    There is a need to help educate the folks here. Most of them know very little about fuels, and are gullible to snake oil like ACES...

    Btw, I think Rude Tim quoted the wrong post.

    Excellent post Mr. Tim ....

    OK so now that we all agree that everyone from the fuel manufactures themselves to the home brew DIY octane booster crowd use Toluene as their base .

    Lets move on to " Xylene "

    Yep on race fuel additives. Most are .... adding real race fuel can also be ...

    xylene is 117 and slow burn some also say it takes lube as it washes things faster then ethanol

    you can buy mtbe (sold as start!) and boost octane as well as long as it’s not already bosted by butyl Ether.

    Just remember aki rating doesn’t mean power. And slow unburned fuel or burning in the tuner doesn’t make power. You might not build carbon and each is different on how much they can take before detrimental effects.

    We de carbonized several one year s a side effect of running 91-93 in 80-100 psi spec engines some even ran fine.

    Go figure.
