I appreciate your input Yellow. The sensor for my EGT is 2-1/2 inches from the head in the primary tube of the header. That seems to me to be a lot faster read than the plugs. Seems to be that the probe would be an instant read, and the plug would take time to change to reflect the temperature of the engine. Now I am not an expert, you probably know a lot more about this than me... but if you read post #23, and still feel this way, then how can I be sure I am not going to burn a valve or what have you in the first few seconds of WOT? I doubt it would melt a piston really, I just want to catch the over heating of my cylinders before it is too late.
The only thing I can gather, from what you have posted, is for me to make runs with the engine tuned, as I have done, it is tuned. Now run one pass up to 60mph WOT, which won't take long by the way : ) Then check the plugs? Then make another 60 mph pass and check the plugs?? And do this about 10 times to see if it is getting too hot? Now if it gets hot, what would the plugs look like? That is my next question. I don't know what a plug experiencing excessive heat would look like. But then, make 10 passes up to 80 mph, checking the plugs after each pass with the modification. All of these would be with the modification on. I can watch my gauges between runs if I need to, but then take it up to 100 10 times read the plugs after each pass. Is "That" what you guys are saying? I am concerned about pass one and two, not 30 passes down the line. That is what I am saying. I want to be sure the first pass isn't too hot for the valves, etc. I would think the valves would go before the pistons. I think I understand you better than the other posters. Maybe it is just sinking into my thick head, IDK. But I am not sure you guys understand what I am saying. What about the first WOT, am I overly concerned about burning a valve? How long does it take to burn a valve? What does a plug that got too hot look like?
