Rpm vs mph

[Dum-Dum]

Hi is it me or does my diesel command hi revs vs road speed ie

3000 rpm @ 70 mph

Nah thats about right for a non turbo diesel. A DT or HDi gearbox will drop your revs lower. IIRC the DT is about 2700 at 70mph and the HDi is 2450rpm at 70mph.

If you do want a DT box im putting a HDi box on mine in the next few weeks so you can have my old box for a tenner.

How so? I cant remember which way it was but in my old d tub if i turned the fuel up or down the revs would sit higher or lower at 70mph it was directly related to fueling

Oh Dear. *shakes head*
