justa6,
Do you just add the Toluene straight? Ithought most people that mix their own added other ingredients to the batch as a lubricant and cleaning agent?
A note: I have researched Home Brews and it seems still cost effective to purchase Race fuel and add it to acheive the octane needed.
I personally think that addressing the Dynamic Comp. ratio Vs. the Static Comp. ratio would be a better solution, at least on most engines.
