Finally got the RS6 on a dyno to see what its got.
Ambient air temp was hovering around 29 degrees so I wasn’t expecting spectacular results. Doing consecutive runs really showed what heat soak does to the car with almost 40KW difference between the best run and the worst run. This also highlighted the inefficiency of the stock intercoolers. Allowing the car to cool between runs allowed us to get a run of 257.9KW with 535nm of torque at 4000rpm.

I’m hoping that the flat spots and dips is the car either moving or slipping on the dyno as I don’t know how hard the car was strapped down at the time.
