OK. Here is some more info. HorsePower per RPM per Displacement is
equal to torque per displacement. Its a yardstick of engine overall
performance. On another website -

- they call it BMEPs.

If you calculate HP/RPM/Displ for each case and multiply by 13,000,000
you will get their "Bureps". Seems like an engine comparison factor.
