EAS's Dyno Sheet: My M5, C63 Black Series, E63TT with PP- same dyno different days
I too have a CBS, and I've had headers and a tune installed on mine. I recently was able to run against a new F10 M5, and honestly I was very surprised with the results...from about 75-135(private airstrip rental of course), The black series walked it pretty hard. I actually started a car length behind the M when we started, and by the end was about a full length ahead of him maybe slightly more. I had run against a 2013 GT-R a few days before that, at slightly lower speeds, and am still surprised because the GT-R was much closer than the m5 was...
Obviously, you never know as there could be driver error etc...but I don't believe that was the case, as I know the driver.
Have you checked this comparo yet Vic? Am interested to see whether my findings are an anomaly.
