Tuning for Max Power - AFR vs. Ignition Timing?
Reading Loren's post the other day regarding the importance of proper ignition timing, AFR's, etc. got me thinking.....
Richening the AFR beyond max power output (POE 12.8-13.2) will allow more ignition advance without the fear of detonation. But richening the AFR beyond POE will decrease max power output.
Is more power gained from richening the mix (to a reasonable level) and allowing more advance timing, or finding POE for your particular setup/engine and set the ignition timing at a safe level (detonation minus a couple degrees)?
What is the general 'rule of thumb' here?
