You can get off MBT timing by 1 or 2% and create conditions that will probably double, triple, (or more) the operating life of the engine operating at very high power settings. At lower power settings, it doesn't make much difference. Regards, George "It is not how hard you run the engine, rather, it is how you run the engine hard - - that matters most." """ <> Back in Detroit (also in the SAE standards) MBT meant "Minimum advance for Best Torque." A good way to approach the subject, as George implied, is to set the advance for some torque loss, say 1%. Then it would be "Min adv. for a 1% torque loss". That would probably be safe for all engines not octane-limited. """
