How to make a turbocharger?

Question

How do I simulate a realistic turbocharger?

Answer 1

VPP doesn't simulate turbo, turbocharger or any forced induction system, but you may implement it by writing a custom add-on component. Vehicles expose all the necessary data and allows runtime modifications of the engine parameters.

• How to write custom add-ons
• The VPVehicleToolkit component contains examples on reading the data from the vehicle. Check out the source code of VPVehicleToolkit for reference.

Modifying the engine parameters from the add-on component require accessing to the underlying VPVehicleController component (the vehicle reference provided in VehicleBehaviour is VehicleBase):

var vehicleController = vehicle.GetComponent<VPVehicleController>();
vehicleController.engine.peakRpmTorque = 250.0f;

That configures 250 Nm of torque at the "Peak RPM" value set in the inspector. This way you may simulate the status of the turbocharger and apply the corresponding torque modification to the engine in runtime.
