My power figures from dyno
test on 3litre auto with 85000k are as follows
max torque=489nm @ 45kph
max power=68.4kw @62kph
motive force=1017.2lb@45kph
Anyone care to comment ,any other figures out there to compare ?

Hi Pepper
You need to have those figures normalized before they have any meaning.
The dyno bloke should give you figures taking into account your drive ratio , wheel diameter and at correct revs.
We know that the typical drive train loss is 30%.
So your 118kw should be around 83kw + - a few at 3200 rpm.
Torque at 2000 rpm should be in NM and around 250nm + - a few.
If they try and give you the story that tyre size is different and you get more loss or other nonsense go elsewhere.
Both my 4800's come in as per above at around 118kw from (180-185kw at flywheel)
