Bottom line, keep the engine cool. Best mechanism? Water.

Does this mean a water jacket around the head? No. There are 911 racers in the SouthWest that use water misters behind the fan that blow misty air down around the heads, using the heat transfer capability to cool the engine in a open circuit (vs. closed circuit of a water cooled head), keeping temps way down. Also the use of alcohol and water in the intake tract keeps charge temps down, mitigating heat.

Even an air cooled motor can be water cooling assisted.
