A »A turbocharger's wastegate controls boost pressure by regulating exhaust flow to the turbine. When boost pressure reaches a set level, the wastegate opens, allowing excess exhaust to bypass the turbine, preventing over-boosting. This ensures the engine operates efficiently and safely while maintaining optimal performance. It's like having a pressure relief valve to keep everything running smoothly!

A »A turbocharger's wastegate controls boost pressure by regulating the amount of exhaust gases that drive the turbine. As boost pressure reaches the desired level, the wastegate opens, diverting excess exhaust gases away from the turbine, thus limiting turbine speed and maintaining the set boost pressure.
