Default 430cc warrior octain boost

Hello my name is Zak. I bought a 430cc big bore kit from powroll.com, a race cam, larger valves, and a larger carb. I put it on my atv, great power, acceleration and speed once i change out sprockets.

What i really need to know is how to make cheap octain boost. I heard that you can use TOLUENE I am running 11.5:1 or maybee even 12:1 compression. I am running 110octain leaded fule, that goes for about 7 somthing at the local sunoco. If someone could give my a mix ratio for TOLUNE:GAS and/or Xylene:Gas i would be happy.

Whats your compression psi wise? You might not even need race fuel.
