octane levels

The easiest way to find out what octane to run (because there are so many variables) with say 10:1 is build your engine the way you want. Put in the highest octane pump gas you can get (if this will be a street car) and get the motor dialed in as far as fuel curve and timing curve to achieve maximum power. Now lower the octane of the fuel you put in until you get to the point of detonation then go back up one step in octane. This is the minimum level of octane that your motor needs to not detonate and will put out the most amount of power. Going higher than this minimum will not do any thing more for power output. All it will be is a waste of money and octane out the pipe.
