I have a spreadsheet that calculates it - 5150rpm is 100.74kph with a 1.35:1 3rd gear, 3.44:1 diff and 165/70/10 tyres
so, about 5150rpm

I love seeing in-car videos of Nb cars changing from 2nd to 3rd at 60mph - screaming! |

Errr.....ummmmm.....Simon, I think there is a BIG error in your spread sheet! Should be about a needle widths under 4000 RPMs. It's 25.7 kph per 1000 RPM. |
