In response to the recent incorrect speedo readings thread some readers may
be interested in the following table showing MPH @ RPM for later MGBs.
It should apply to most B's (except earlier cars had a different first gear).
Assumes 24" diameter wheel/tyre (measured on my 165-14s) and 3.909 axle.
RPM 1st 2nd 3rd 3rd OD 4th 4th OD
1000 05 08 13 16 18 22
1500 08 13 20 24 27 33
2000 11 17 26 32 36 44
2500 14 21 33 40 45 55
3000 16 25 39 48 55 66
3500 19 29 46 56 64 78
4000 22 34 53 64 73 89
4500 25 38 59 72 82 100
5000 27 42 66 80 91 111
5500 30 46 72 88 100 122
6000 33 50 79 96 109 133
Anyone wanting a copy of the program that generated the table is welcome,
just email me.
