I too am a bit confused... especially since, generically, I have experienced a 15-20% difference between Whp and flywheel hp.. thus 231 whp x .15 yields 265 flywheel hp, which isn't far off Porsches typically conservative HPO rating of 252-258 depending on year.

While I have never said you couldn't get more HP, one should realize that for a "world" market that uses the car under all sorts of conditions, certainly Porsche leaves some HP on the table...
