Supercharger

Engine-driven forced induction compressor that provides boost pressure proportional to engine RPM. Delivers linear, predictable power gains without turbo lag.

Engine-driven forced induction compressor that provides boost pressure proportional to engine RPM. Delivers linear, predictable power gains without turbo lag. Typically a sub-module of the Combustion Engine, driven via belt or gear.

Public API

VariableTypeDescription
isExistingbooleanWhether a supercharger is installed on this engine.

Hooks

HookDescription
initInitializes the supercharger from JBeam data and links to the parent engine.
updateGFXUpdates boost pressure calculations and UI feedback each frame.
updateFixedStepPhysics-rate update for pressure and torque calculations.

Usage Example

-- Access via the engine device
local engine = powertrain.getDevice("mainEngine")
if engine.supercharger and engine.supercharger.isExisting then
  log("I", "sc", "Supercharger installed")
end

Split Shaft

Powertrain device that splits rotational power into two output paths. Used for driving two systems from a single input, such as front and rear axles from a transfer case.

Torque Converter

Fluid coupling device that transmits and multiplies torque between the engine and automatic transmission. Allows the engine to idle while the vehicle is stationary.
