This formula has been floating around so I'll take mine as an example:
I make about 570 RWHP. Taking this formula:
X = base horsepower
X + ((X* PSI Boost * 6.8) / 100) = Approximate horse power
So my base (NA) is about 405 and I'm running 6 PSI Boost
That would mean:
405 + ((405 * 6 * 6.8)/100) = 570.24
So, if I increased my PSI Boost to say 9, I would be close to this:
405 + ((405 * 9 * 6.8)/100) = So it would be around 652.86
Now there are alot of factors that need to be accounted for (temps, flow, cam, injectors), but this is a 'general' rule and not an absolute. To me, I'd subtract 5% to be safe so I would take into account the other factors...
Do I think this is 100%? No, but it is math and the 'mean' of 6.8 and 100 is part of the formula (can't remember what they represent -- its been a while and I'm old ;o)
