The reportI read claims they found a "substance" in the manifold that indicates the addition of a material that would boost the octane of the fuel. Now I don't know what octane fuel they are burning in the cars or whether the octane rating is limited, I do know that the octane rating is simply the ratio of iso-octane to normal heptane in the fuel. A "substance" could increase the performance number (anti-detonation) quality, but not the octane rating. Incidentally, there is no such thing as an octane rating of over 100..you can't have more than 100%. Re the Waltrip car affair.
