Greg;

Does "everything in the free world" include directly measuring EGTs with thermocouples and not indirectly with the IR thermometer...maybe its time to change your method.

I'm trying to think of what might be the cause of the difference with No.1, and I have to admit I can't think of much... maybe a leaky injector causing a (very) rich mixture, but you'd see evidence of that on the spark plug....

...besides, I question the value and usefullness of IR thermomometer measured temps....unless you have the car on a dynemometer and under load at the time you're cheching, and taking the readings, they are only unloaded temps...I would much rather be able to monitor EGT under load.

The homebuilt aircraft supplyers such as Wag Aero have thermocouple EGT kits which you might want to try. You can either work thermocouples directly into the exhaust stream, or use the much simpler, but less direct, "under-the-spark-plug" type.

Cheers
