Pump gas compression

"The can build more or release more compression driving the PSI in different directions which can be very different that just a dead straight up mathematic number of static ratio."

as far i understand engine doesnt release eny compression when its operating in area of higest torgue in rpm range. Therefore it has same cylinder filling% = compression psi as smaller cammed engine. Thats why i dont get it why bigger cammed engine wont detonate like smaller cammed engine.

Ok. maybe I just think too much.
