For instance,

F20C - 1,997 cc - Output: 234 HP/155 ft lbs
2.0 L SkyActiv-G - 1,998 cc - Output: 155 HP/148 ft lbs

One engine literally makes 79 more horsepower yet they are classed the same. I think really any sanction using displacement to class cars might want to get with the times haha.

So go off stock HP numbers? Or actual? Dyno the cars as part of scrutineering

Actual, from a specific type of dyno corrected to standard temperature, and atmospheric pressures.
