Does anyone know the revs per mile figure for the Type 9 5-speed box. I'm using a Greengauges quenched oscillator speed sensor and need this for the calibration. I'm sure this figure's been given before but I can't find the post.
Original gearbox donor was a 1989 1.6.

Thanks,

Geoff

What final drive ratio do you have? Gearbox is not relavant as speedo is driven by third motion shaft that turns prop
