See below for some worked examples:
2005 VVT manual gearbox Jimny, engine at 4000 RPM and in 5th gear High Ratio
| 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 |
2005 VVT manual gearbox Jimny, engine at 3000 RPM and in 1st gear Low Ratio
Gearbox input = 3000 RPM
Gearbox ratio = 4.425
Gearbox output = 678 RPM
Transfer box input =678 RPM
Transfer box ratio = 2.002
Transfer box output = 338.6 RPM
Diff input = 338.6 RPM
Diff ratio (final drive) = 4.300
Diff output = 78.5 RPM
Wheel input = 78.5 RPM
Wheel diameter = 28 inches
Road speed = 1.5 miles per hour
