It's no secret that Honda builds one of the best-flowing heads out there. It's tough to compare their flow #'s to anyone elses. especially with the overlap they run.
In either case, to back on Dan's 8 year old post, I do remember the DSM guys that were way faster than me and were running in the 10's for AFR for power talking about having to take a leap of faith with tuning AFRs and getting into the high-11's. This was mostly around the time link replaced AFCs, since AFCs would lower the MAF signal so much it would put the ECU into REALLY aggressive tuning maps, and DSMlink would allow to change injector profiles the correct way, and leave timing/airflow alone.
In DSMs the stock intake/head always lead to knock in #2 I believe, and I don't know if anyone ever discovered if it was due to fuel delivery, port shape/airflow etc. It could have everything to do with the extremely short
On the Wagon, and Saabs in General, they do really well and make good power at 12-12.5. It's a lot to do with the intake/head, but I think a lot to do with the longer exhaust manifold runners allowing for less collision of the exhaust pulses, and less heat/recycling of exhaust.
If only they had not put these stupid cast hypereutectic pistons in...we'd be able to take advantake of the otherwise great engine design.

So your real question is that you are trying to pick out injectors right? Design for their optimistic turbo BSFC values and that will leave you some headroom for when the weather cools off and you need the extra fuel.
