I don t know that true values for the 2B or 3B but the 2B has a higher compression ratio than the 3B Since the 3B is only a little bigger than the 2B it is quite possible that the 2B has a little more power Size is not the only indicator of power compression ration valve timing injection timing pressure and many other factors determine the final HP figure However it does look like the 2200 rpm for max torque value was used for both torque and HP The true rmp for max HP is probably in the 3000 3600 rpm range ie similar to the rest of the range but I don t know the exact value and I prefer no value rather than a guessed value
