So to say that modeling it using forced induction or not, is not a likely scenario than I think you're mistaken. Granted not all conditions can be thought of in the design stage, but in my mind I would think that they would pick the worst of worst scenarios and go from there. I.e) desert temps, to Arctic temps, to plugged filter, WOT with cold oil and go from there. The forces is the easy part, the hard part would the air flow through the engine to maximize fuel economy, power, reliability, drive-ability, etc. Fuel emission requirements are getting tougher and tougher, so to make 100 hp/l is amazing, granted its no 240 like the s2000 but the s2000 had less requirements to meet when it was brought out.

I still stand by my point that they're not going to bet the house on the fact that those calcs are right and tell tuners/owners that, "12 psi is like, totally okay!" and then risk lawsuits when idiots start blowing motors with bad tunes.
Achievable power levels are all in the tuning. A good tuner can get much more power out of the same engine, and have it do that all day every day, than someone who doesn't have the knowledge or experience to get things right. Detonation and other problems kill engines way quicker than the number of psi being shoved into the thing or the amount of HP being cranked out.
