thanks for posting this map, it seemps interesting to do the maths also with 1.6L 4 cil engines that they seem to share engeenering. I thing also that it is importatn to think that the sweet spot of low bsfc will move depending on wich turbo you fit.
where did this map came from?
your chart remember me thaat of 2.0 L VW diesel engine with 140 hp, too big turbo for fuel economy at low speeds.
You are facing a big challenge even with such a big car.
