the bsfc factor includes effect of engine thermal efficency ... saab turbos are very good at it. a value of .6-.65 is more appropriate for a rotary turbo with lots of wasted heat, .45 for stock saab turbos, .5 for minor mod'd saabs.
80% duty cycle is very conservative too. as 85-90% is exceeded, you go richer than intended such that 95% is like 100%.
so with maxed stock C900 inj'rs at 2.5 bar, 4x21/.45=185 hp. with 3 bar fpr, 4x23/.45=204 hp.
