See below for some worked examples:
2005 VVT manual gearbox Jimny, engine at 4000 RPM and in 5th gear High Ratio, standard wheels
| Engine | Gearbox | Transfer Box | Diff | Wheel | |
|---|---|---|---|---|---|
| Input | -------- | 4000 RPM | 4000 RPM | 4000 RPM | 465 RPM |
| Ratio | -------- | 1.000 | 1.000 | 4.300 | 28" Tyre |
| Output | 4000 RPM | 4000 RPM | 4000 RPM | 465 RPM | 77.7 MPH |
2001 M13A manual gearbox Jimny, engine at 3000 RPM and in 1st gear Low Ratio, 30" Tyres
| Engine | Gearbox | Transfer Box | Diff | Wheel | |
|---|---|---|---|---|---|
| Input | ------ | 3000 RPM | 821.4 RPM | 382.9 RPM | 97.97 RPM |
| Ratio | ------ | 3.652 | 2.145 | 3.909 | 30" Tyre |
| Output | 3000 RPM | 821.4 RPM | 382.9 RPM | 97.97 RPM | 8.7 MPH |
2001 M13A manual gearbox Jimny, engine at 3000 RPM and in 1st gear Low Ratio, 30" Tyres with Differential from later VVT
This shows an example of a modified diff with an increase reduction ratio
| Engine | Gearbox | Transfer Box | Diff | Wheel | |
|---|---|---|---|---|---|
| Input | ------ | 3000 RPM | 821.4 RPM | 382.9 RPM | 89 RPM |
| Ratio | ------ | 3.652 | 2.145 | 4.3000 | 31" Tyre |
| Output | 3000 RPM | 821.4 RPM | 382.9 RPM | 89 RPM | 7.9 MPH |
