Right. I've read in several places that detonation and/or blow by often occurs during low RPM and WOT. (I guess that's due to the relatively slow moving piston and the higher forces from more fuel combustion puts a lot of force on the piston and rings, where the rings are the weaker of the two).
But I'm also concerned with the the piston ring wear at higher RPMs. Higher RPMs simply mean more cycles which means more wear and tear from sliding up and down the walls.
Anyways, please have patience with me. As you can see, I've read up enough to become dangerous to myself but am by no means an expert.... which is why I'm posting threads like this: to learn more and more importantly PUT THE UNDERSTANDING ALL TOGETHER.
