Class ForcedInduction

Simulates forced induction systems (turbocharger or supercharger) for piston engines. Models turbine RPM inertia, exhaust-driven vs belt-driven boost, wastegate and blow-off valve.

hasBlowOffValve

Simulates a Blow-Off Valve (BOV). If true, boost drops rapidly when throttle is released.

Declaration
public bool hasBlowOffValve
Field Value
Type Description
bool

public float maxBoostPSI
Field Value
Type Description
float

normalizedBoost

Normalized boost value (0 to 1) relative to maxBoostPSI. Useful for UI gauges.

Declaration
[Tooltip("Normalized boost value (0 to 1). Used for UI.")]
[Range(0, 1)]
public float normalizedBoost
Field Value
Type Description
float

parasiticLoss

Parasitic loss at max RPM (percent of power lost to drive the belt).

Declaration
[Range(0, 0.2)]
public float parasiticLoss
Field Value
Type Description
float

spoolInertia

How fast the turbo RPM can change. Lower values = Heavy turbine (Laggy). Higher values = Ceramic/Ball-bearing (Responsive).

Declaration
[Range(0.1, 5)]
[Tooltip("Inertia factor. Lower = More Lag. Higher = Faster Spool.")]
public float spoolInertia
Field Value
Type Description
float
