speedo inacurate
« on: April 17, 2007, 22:22:30 »
Hi I have just about finished a total rebuild of my 90 it,s running a 200tdi with a 1:22 ratio transfer box and 265/75x16 bfg muds, anyone any idea what speedo drive gear I might need it appears to be reading too low at the moment.

Cheers

I run a Disco transfer-box & 265/75 X16 BFG AT's with the blue drive-gear on my 90 and my speedo reads as follows:-

Ind 30MPH = 28MPH on GPS
Ind 55 MPH = 53MPH on GPS
Ind 75MPH = 72MPH on GPS.

Also around here we have those illuminated boards which tell you your speed as you drive towards them and they bare out these figures.

mine runs the other way. 200TDI with a 1:2 transferbox
30mph = 35 on GPS
50mph = 58 on GPS
65mph = 74 on GPS

before I had GPS i was happily pootling around at 70 thinking i was totaly above board...dread to think ho fast it was actually going when on the odd occasion i actually got 80 (private road) :shock:
