So why is this engine less efficient than the FA20 anyway? Any thoughts? Less aggressive cams emphasizing more low-end?

I mean, with the same redline and a similar torque curve I’d expect a horsepower increase to be roughly equivalent to the displacement increase, which would put it at 246hp. But this engine is a full point higher in compression, yet still gets an 11% hp bump out of a 20% displacement bump? Doesn’t feel right; I thought specific output would go up, not down.
