Diff Ratio's

[NAH]

Does anyone know what the diff ratio is for a stock 2004 CV8? In the standard tune file from Holden Crazy, the ratio is 3.5, is this correct?

3.46 to be exact

Yes, I see that now. 3.5 must be a rounded number, thanks. Chris, can you FAQ this info?

Will do, but I need the info on other cars as well first...04/05 CV8/VXR ... GTS/GTS-R

This could get ugly!

GTS = 3.73
GTS-R = 3.91
V2 series III CV8 Monaro = 3.46
V2 series III VXR Monaro = 3.73

I think it might go pear-shaped from now on as I know some of the later HOLDEN cars got 3.73's in them too, I don't know what the cut-off was or if the UK cars were included in this. It might just have been the sedan versions SV8/SS. Pretty sure the VZ 6 litre HSV GTO/VXR diff went back to 3.46.

VZ Monaro = 3.46/3.73?
VZ Monaro VXR = 3.46?

Caspy, ukhsv or island-boy should be able to fill in the blanks!!
