GearBox Ratio's required for Road Dyno
 

Does anyone have the knowledge to post all of the gearbox ratio, starting with the Classics.
Trying to setup Dataloglab road dyno but the default figures and ratio's in the Impreza Book are all to cock. Hence my initial runs in my own car have my ATW figures looking more like Fywheel Figures.

So they are either wrong or don't take into acount the drop gears.

i.e
MY98-00
1st 3.454
2nd 1.947
3rd 1.366
4th 0.972
5th 0.738

Final Drive 3.545, 3.90 or 4.111


It doesn't mention anything about a Drop gear of 1.1:1 on 3.545 which makes it equivalent to a 3.90

My own car is a MY00 UK so assume it has the 1.1:1 drop gear, if not then a spreadsheet I have found reckons with the specified 3.545 Final drive I can get over 100mph in 3rd :eek: (I don't think so)

Idealy I want :
1993-2000 UK
1993-1996 WRX
1993-1996 STi
1993-1996 RA

Cheers....

have a look here
The SPDA - Transmission Chart

Cheers, the ratio and final drive now seem make bit more sense.
This give me 90mph @ 7000rpm in 3rd which sounds about right.
