For the street I will run 93 octane, but when I go to the strip will I benefit from the higher octane racing fuel? I think it is around 105-108 octane. Thanks. Theres really no reason to up the octane unless you just plan on being safe. Also if you up the octane without adding some timing.... you would go slower. The cam makes a big difference in the cyl pressure... when it closes
