I know it’s far from an exact science but rolling road tests I’ve seen of the R and S3 seem to point to the cars producing more power than official manufacturer figures, and as a comparison the M135i and the JCW thing with side opening rear doors that it shares a chassis and engine/gearbox with produce less than the 306 PS BMW group rate it at.
For consistency purposes Racechip (I know, I know) have released videos of some of these cars showing comparative figures on their own rolling road. Unfortunately not all in the same video. Whether their rollers under or over read or not the difference between each unit’s output should be fairly consistent.
