On a slightly different tangent: what has been your experience with a target octane, for example, on a 11:1 CR motor? My understanding is that you are wasting money with overkill, i.e. too much octane or running straight 110 octane racing fuel. Where is the point of diminishing returns? Is the lower end of this (i.e. too little octane) defined by detonation and or poor engine performance? Guess I am looking for a formula or procedure to determine target octane with an eye toward maximizing performance and balancing that with cost effectiveness. Any lessons learned out there?
Thanks!
