I just wanted these to calculate the speed of the 6MT & of the DCT at any given gear & engine rpm, which I did in an excel spreadsheet and seems to be working (I cross checked my findings for the 6MT with a couple of magazines that report top speed for each gear).

According to my calculations, the (theoretical) top speed at 8,400rpm for the stock 6MT and DCT is 302km/h and 321km/h respectively (assuming that the engine is allowed to rev up to the redline in the top gear on each car and assuming that it has enough power!).
For the first time BMW has a shorter gear ratios for 6 speed manual in its M cars:
E36 M3 EVO 6 speed with 3,23 diff and 0,87 6th gear ratio could do theoretical 330 km/h (roughly; I don't remember exactly)
E46 M3 6 speed and SMGII with 3,62 diff and 0,87 6th gear ratio could do theoretical 330 km/h (roughly; I don't remember exactly)
Now E9X M3 only do theoretical (probably real) 302 km/h (which is better than previous 6MT final drives in terms of performance since it is possible to hit 302 km/h with a de-limit M3 )

I had 3,64 Schnitzer shorter diff on my E36 M3 EVO coupe. I could hit the rev limiter in 6th gear, which was at 7600 rpm. It does 298 km/h real speed. (I'm talking about euro spec 321 hp M3 with full SS exhaust)
