That would be 2 WOT BSFC and a proper BSFC map.

Come on.....The engine data images you posted were forced induction. (I assume the 1st one was even though I can't find data on it, the BMEP was 150?)

The first image you posted above - The R26B engine is a turbocharged quad rotor, rotary race engine. Post something that is normally aspirated and in production for consumer use for comparison.

A quote from Wikipedia.... "The engine design originates as a single 13B with: an additional rotor and housing added at each end, continually variable geometry intakes, and an additional (third) spark plug. The R26B's rotor housing can be purchased at retail from Mazdaspeed, but no internal parts are available to the general public."

The second MEP graph was a supercharged Mercedes engine. Post something that is normally aspirated for comparison.

Note: The supercharged Mercedes engine's best BSFC was around 250g/kW-h. Our best was 17% better or 6.8% better in total efficiency at our peak and normally aspirated. Forced induction decreases the total percentage lost in pumping losses as apposed to power gains.
