If we assume that we will avoid crank flex from high RPM resonance and
detonation from bad boost, stresses rise fastest with high RPM. The
parasitic stresses of accelerating and de-accelerating the rods and pistons
at high RPM is actually larger than the stresses of high HP from boost at
lower RPM.
Your choice is usually to spend money on strong parts that can handle high
RPM or to spend money on tuning to avoid detonation during high boost. The
tuning is usually more expensive especially if you make a mistake on your
way there. (oops, you got another engine?)
