What Causes the Supercharger to Glow Red?

[Serena]

Supercharger glowing red is a normal phenomenon. When the engine exhaust temperature reaches 730°C, the supercharger housing begins to glow. During normal engine operation, the maximum exhaust temperature ranges between 850°C and 880°C. The supercharger housing can withstand temperatures up to 1050°C, so glowing below 880°C is considered normal. Symptoms of a damaged supercharger include: 1. During rapid acceleration, hearing the exhaust valve scream above 1750 RPM is normal; 2. When pressing the car's odometer, abnormal noises inside the second turbine indicate damage; 3. If the car's turbocharger is faulty, the engine warning light will illuminate; 4. It can lead to incomplete combustion in the engine, resulting in strong exhaust odors.
