Displacement

It is more about displacement and mass of reciprocating and rotating components. I don't know the record holder for V8 on hp/l but the smaller the displacement the higher the revs and the higher the hp (of course assuming all other engineering top notch). Just look as 1 liter superbikes, ~15k rpm and ~180 hp/l.
