you are correct, the numbers are nearly the same for
current subaru boxer 4 engines, unlike conventional inline or v configurations which power characteristics have a slightly larger rotational power difference in hp and tq relations. flat-6s have a larger difference compared to the flat-4s...but TQ characteristics are still unlike more popular engine configurations.
