    #8 is 0.57AR so very good EGTs and power then from a really good modified engine i would say.

    Hardly though the most representative HX35 numbers i would say..

          The spoolup is fair if 8cm² would equal an A/r of .57
          A very likeable torque curve i must say, but i would like the rest of the engine specs. Think it has an uprated WG to overcome the choking if it is this small.

              Ah yes, makes sense. No need for a V60 if looking at the plot.

              Thnx Thuppu

                        No, i believe they simply remove the rotating assembly for somethis smaller.

                            It is very good IMHO for this power level according to its dimensions.
