It is a "steady state" dyno, my understanding is that it locks the RPM and then measure the maximum torque that the engine will provide even if it takes a certain time to provide the torque. I assume this means for example 1300 RPM locked and then they give full trottle and wait for the engine to give all it has at 1300 RPM. I guess this is why its called a "steady state" dyno.

The head of Rototest told me that the industry is working on a standard way of measuring engine behavior like lag during acceleration etc. He also told me that he as a industry professional found our worries "very interesting" and it would be a very strong proof if a car that was tested differed from the "old" 335i they tested back in 2006.
Hmmmm, then I wonder if this will show The Lag... if you maintain throttle at 1500 RPM, even with 29.2, you will eventually get boost, which means that maximum HP/torque at that RPM probably won't be any different than pre-29.2.... thoughts?
