speedo gears for t5

22-02-2006, 08:08 PM

i've been thinking about fitting some 3.9 diff gears and was wondering if you can get speedo gears for for a t5 simalar to the ones they use for the auto's.i don't want to go to the expense of fitting a chiptorque chip or edit to get the speedo corrected.
thanks,jake

Ive got the 3.73 diff ratio.Luckily I also have a navman which accurately tells me true speed.I have installed the black speedo cog and at 90 kmph my speedo still reads 100 kays. I am thinking about having it done professionally.

for daily driving ,the speedo being out wouldn't worry me .just when i go out to the track for a play the speed limiter will be shutting it down before i get to the end of the track.
svo347 checked that sight out but they don't have none for the au's

with the xr's running 3.45's did they change the speedo gears or was the speedo corrected by recalerbrating the computor?

Do you have a speed limiter? I know many people here talk about speed limiters but..my AU1 on 2 dynos hit a genuine 210 /220 kmph unedited untouched without stoping. Maybe yours too??
