gear ratios?

[Col_M 0]

Does anyone know the gear ratios inc. final drive for the VR box?

I found this on vwvortex but these seem to be for an american version, i seem to remember that they had different ratios to us though, did they have different ratios?

1st: 3.62:1

2nd: 2.07:1

3rd: 1.47:1

4th: 1.04:1

5th: 0.84:1

Final: 3.39:1

cheers, there is a distinct lack of info regarding this, i've seen hearsay (not the manufactured band thankfully) but no concrete or a definitive source.

For a UK VR, I have the ratios as down as:-

1st - 3.78

2nd - 2.12

3rd - 1.46

4th - 1.03

5th - 0.84

FD - 3.39

The ratios are the same for 2.8 and 2.9 engines.

VW did play about the with ratios a fair bit so it's hard to say 100%. Best thing to do is get the 3 digits that suffix the '02A' stamp on the bell housing and the dealer should be able to tell you the ratios, or Vince at Stealth will know for sure.

Thanks Kev, I also asked the question on ClubGTI and got a slightly different answer again.

1st 3.300

2nd 1.944

3rd 1.308

4th 1.034

5th 0.838

FD 3.389

I think like you say the best bet is to find the 3 digit code and ask someone who can tell me, i'll probably ask Vince at Stealth on the 18th. I don't need to know right now anyway, it's for a uni project after xmas, i'll be calculating the theoretical 0-60mph acceleration of my VR in Matlab Simulink

If anyone's interested this is similar to what i'll be doing...

That is for the lecturer's porsche and doesn't include pressure losses in the intake and gear changes.
