Relationship between knock, AFR, timing, and EGT?

[jspaeth]

Can someone explain to me how knock, AFR, and timing are related to EGT?

I understand how AFR and timing can influence whether there is detonation (knock) or not.

However, my real question is:

Are knock and EGT independent of one another?


The reason I ask, is that when tuning a motor's fuel and timing, typically the tuner pays attention to AFR and knock, and adjusts fuel and timing appropriately.

However, high EGT can also cause damage.......but many times, a tuner doesn't monitor this....


Are high EGT directly related to knock? In other words, can you get unsafe high EGT without having lean AFRs or high knock counts? Or do high EGT come as a RESULT of lean AFRs and high knock counts?



Thanks
