bhp figures etc

[axeman]

just wondering how vw got there power and torque figures, as i had the van on a rolling road to have a proper tune up as i fitted a new twin choke carb and it needed properly setting up (jeting etc)

the van performed quite well getting
115bhp at the fly wheel @5200rpm which is 93bhp at the wheels
148ft/lb at peak torque @2900rpm at the wheels

so it makes me question if the car companies when they give bhp and ft/lb at the fly wheel or the at the wheels. it is obvious that a bigger figure looks more impressive from a sales picture

i have had a quick look around and i cant find and torque figures for any of the wbx engines, dose any one know the figures?

they usually do it from the fly wheel. looks better but not real bhp in my opinion.

aye - they also do weights with 'dry capacity' also which does my nut in!
