Can someone tell me what speeds are available in the gears on a Roadster please?
I think there are three sets of ratios for the 3.0 Roadster. We've talked about it before a long time ago. The S1 (Getrag)has a 1:1 5th gear with a 3.07 diff. The S2 had an overdrive 5th (Ford) - about 0.89 is typical, with a 3.7 diff as far as I can remember without looking it up. The S3 may have changed again.
The S2 is slightly higher geared in top than the S1. I find the S1 very slightly undergeared on the Motorway - a 6th speed at 0.85 would be fantastic!
Intermediate ratios I would have to look up......
From Morganatica for the 3 l S1
Mph/1000 rpm (top gear) : 23.67
Mph at 2500 ft/min, piston speed (theoretical) : 113.6
Final drive ratio : 3.08
Overall gearing in top gear : 3.06:1
Indirect ratios:
1st gear : 4.23
2nd gear : 2.52
3rd gear : 1.67
4th gear : 1.22
5th gear : 1
Reverse : 3.51
Clutch : single dry plate
Rear axle : Tubular live axle with hypoid gears and limited slip.
