A lot of the
JCW 210s seem to RR @ around the 195 at the fly mark. The 200 seems to RR at not far from the same.
185 seems a bit low, but this could be because the place your using is not got good fans, the S needs lots of cold air to simulate a real life conditions test and many RR don't get enough air into the engine and over the struggling stock IC to simulate higher speed and open air road conditions.
