Diff is only the starting point. Heres an idea of what wheel size can do.
This on mine .83-5th & 3.54 diff.
Tyre 205/40/16 = 22.71mph/1000 8.4k = 190.8mph
Tyre 235/40/17 = 24.68mph/1000 8.4k = 207.3mph
Tyre 235/40/18 = 25.69mph/1000 8.4k = 215.8mph
Tyre 225/40/19 = 26.38mph/1000 8.4k = 221.6mph
If i was running the 1k at totb with 900bhp the 16's set would be my starter with 900bhp over 1.5miles the 18's would be the starting point.
