300 HP from a 3L is certainly interesting, but not unfathomable. How does Honda do it? With variable valve timing and high RPM's. If you want some comparison, look at the S2000 engine. 240 HP from 2 litres - however at 8K RPM. Also look at the torque output from this engine - miniscule. Makes for a racy engine, which doesn't necessarily do well on the street.
