Consider for a moment that a stock PDK 997.2 turbo runs door to door from a roll with a Ferrari 458 Italia. Both cars are just shy of being 130 mile per hour trap speed vehicles. The M6 stock hits 123 mile per hour traps according to recent tests. Stock for stock, the 997.2 PDK turbo is quicker and faster than the new F13 M6.
So this video shows a tuned M6 instantly putting bus lengths on a 997.2 Turbo PDK just like it did to the LP560 Gallardo. That would require a HUGE power disparity. Is the PP-Performance tune getting the M6 to the 130 trap speed range? Sure, gaining around 70 wheel necessary to hit that area seems realistic. But that would make the race close with the M6 edging up top, not the instant one sided affair it is portrayed as.
We need more data but dynographs and trap speeds from the USA will shed more light. Roll on race videos like this can be quite misleading especially without supplemental hard data. The M6 looks like it gets a huge jump to begin with on the first run and the second run is mis-timed on the honks. Simply take it with a grain of salt and M6 owners don't expect to go around annihilating Porsche 911 Turbos.
