HP comes from torque, so in order to get more HP, you have to either have more torque, or make the torque peak higher in the RPMs so that it generates more HP. Without torque in a rotational engine, there is no such thing as HP.

That is correct. Except... "or the torque it does make has more
inertia behind it".? There are no free lunches in thermodynamics. Torque is Torque (or force is force).
Inertia is simply stored energy (HP) that came from the engine at some point in time.
BTW, a quiz. Ever seen an engine that produces maximum torque at zero RPM?
