I'd also like to add the reality check that dyno's do not read the same (from one to the next), and its dangerous to assert (at any atmosphere) that dyno figures are universally discrete. I want to go on the record with that.
Dave, I believe that your uncorrected figure is realistic, if you went to a sea level dyno, I think you'd see a mild increase over those #'s, but no where near "Corrected figures".
I like quoting uncorrected figures for turbo motors, but this still doesn't make up for the huge disparity in dyno calibrations, which make quoting HP figures almost useless anyway.
Dyno figures are ultimately useful for comparing the same motor to its past performance. I _always_ run on the same dyno for this reason, as dyno #'s are only very valid for baseline comparisons.
