It's the same link that footie posted and i just quoted the article. I'm just saying they base it on the % loss of the 330i dyno run and calculated or estimated the 335i run with those results. I'm not necessarily agreeing with it, but it is known for most cars to lose between 15% to 20% powertrain hp when testing on a dyno.
