What happened to the pressure drop of Passat supercharger throttle connection?

What's the pressure drop of Passat supercharger throttle connection? What's the pressure drop of Passat supercharger throttle connection? Check whether the booster pipe is damaged. The reduction of throttle connection pressure of Passat supercharger is caused by damage of exhaust check valve or air leakage of booster pipe. The main function of the check valve is to prevent gas from returning to the crankcase of the engine. Failure or damage will lead to air leakage and insufficient pressure. The reasons for insufficient pressure in the supercharger are as follows: 1. The air filter of turbocharger is blocked, which increases the suction loss and leads to insufficient boost pressure; 2. Inside the compressor/when the airflow passes through the channel with too much grease, the airflow resistance will increase and the boosting pressure will decrease. 3. Poor fuel combustion leads to carbon deposition on the rotor, or damage to the bearing of the supercharger leads to increased rotational resistance of the supercharger. , it will also cause the reduction of boost pressure.
