I need higher octane, booster?

[Stomis]

Bet ya a lower temp thermo will take the knock away. When I was building my camaro everyone told me that if you build a motor right on the brink of needing the next octane fuel it will most likely knock in the summer due to the atmospheric temp.

And just to let you guys no the octane boosters arent a hoax or a joke. The ones we have at work all say how much gas they apply to and how much they will raise that amount of gas.
