i was always under the impression that valves become a weakness if you are trying to make the motor rev higher, not if you are trying to boost it

i can't find the math but apparently the percent increase in the forces that the rods and pistons feel is much higher from high revs than from boost.. like.. i think the example the boost used was if you took a motor and tried to rev from 7000 to 7500 you will put more added forces on the rods/pistons than if you boosted the motor and kept the original 7000 rev lmit....
