Interesting, but at least for me... some data is missing or not shown.

Data about VE (Volumetric Efficiency) and BSFC (Brake Specific Fuel Compsumption) is available? not only is a matter of HP/Torque at X rpms. Looks good, but for me some vital data is missing, are the data that shows how good transforms every gram of fuel into moving energy (on few words: how really good is).

Probably another pull from 7500 rpms could be more graphical and show the real performance of the engine rather than peak values. Maybe a normalized fuel, like 30% O'Donnell, could help too.
