I am amazed at the reaction time of his EGT gauge. I ran these gauges 15 years ago and almost melted a piston. You could hear the engine long before the gauge reacted. After watching the video I heated the probes with a propane torch and no way they would simulate the reaction time of his EGT gauge. Subsequent cleaning of the probes resulted in a faster reaction time to heat but the gauge took far to long to return to a cooler value even when blowing cold compressed air on the probe.

The guages I ran were that quick, or quicker. I think it has to do with the probe quality.

Not quality so much as thermal mass. In general, some temperature probes are designed for quick response and some are not. Usually the slower ones are slower because they are more robust, with protective tubing around the sensor, etc..
