AndyAndyF_RSX said:No it shouldn't because you won't actually see the way the turbo can perform on the road.
Because the loading of the rollers is bound to be different to the loadings on the road, the turbo can be made to produce good spool up by upping the loading of the rollers as the car is coming on boost.
This in away opens a can of wormsAndyF_RSX said:Yes, of course it can be distorted by thte operator due to the way in which the r/road works.
All you have to do is alter the loading of the rollers in a gear to give a really high load on the engine and the turbo will spool up quickly. Put a lighter loading on the engine and it won't spool up as quick.
However, as all the cars are generally tested on the same day using the same settings on the rollers then you would be able to see the differences just from looking at a boost curve rather than needing to plot the spool up time, provided that everyone was running the same boost levels.
