Practical examples

See below for some practical 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 30" Tyre
