Engine Torque
Important
Accurate engine torque modelling is critical for transmission performance.
Engine Inertia
Engine inertia is used to calculate the clutch torque required to sync the engine speed during a shift. It also informs the rev-match torque calculation.
| Engine / configuration | Typical Inertia (kg·m²) |
|---|---|
| Small 4-cyl light flywheel | 0.12 – 0.20 |
| Typical 4-cyl production | 0.18 – 0.28 |
| Performance 6-cyl (light flywheel) | 0.20 – 0.32 |
| Heavier 6-cyl / street flywheel | 0.28 – 0.40 |
| Big heavy flywheel / truck | 0.40 – 0.70+ |
