What happens if the supercharger bypass valve stem is shortened?

[TheoMarie]

Shortening the supercharger bypass valve stem will increase turbo pressure and may harm the durability of the car. The supercharger bypass valve can control the supercharger pressure by adjusting the length of the valve stem. The relationship between the bypass valve and the supercharger: The bypass valve can be understood as a pressure relief valve. It mechanically adjusts the speed of the supercharger to reduce the boost pressure. When the engine runs at low speed, the outlet pressure of the compressor is low, and the bypass valve closes under the action of the return spring. The bypass valve is an essential device for turbocharged engine cars, as it protects the turbocharger. To protect the turbocharger, when the engine speed is too high, the bypass valve opens to avoid excessive pressure or speed in the turbocharger. All the exhaust gas from the engine passes through the turbine end of the supercharger, increasing the turbine speed, generating greater intake boost pressure, improving the intake volume, and enhancing the engine's low-speed performance. As the engine power increases during supercharger operation, the increasingly strong airflow entering the turbine housing will raise the temperature of the turbine housing.
