chassis dyno hp accuaracy
May I share an obsession with "Porsche turbo crank hp" which I learnt about earlier this week.
RS Tuning on an annual basis test a random turbo engine on a scheduled day on their engine dyno and convert to "Porsche turbo crank hp" using their software then the same day the engine is taken in a van to Porsche Weissach (which is 500m higher -needed for correction) and put on their engine dyno and a maximum power number obtained using Porsche software. It usually comes out within 5 hp.....
I am told that "Porsche turbo crank hp" is actually slightly higher than a strict DIN calculation.
Just thought I would share this in the light of some of the chassis dyno power claims around, 671 "crank hp" on a stock VGT 997tt for example - the market has gone truly bonkers

Is there one ?
The latter I think but with stock VTGs which measuring on a Porsche "calibrated" engine dyno will not give more than ~550PS DIN
