Key Symptoms Of A Bad Or Failing Supercharger Belt

The supercharger belt is and has always been one of the most critical parts for the efficient operation of the supercharged engine ensuring that the blower belt is in intact and in good shape. It is one of the crucial parts of the routine services that anyone should perform. It is nothing new and like any other mechanical device, the supercharger belt can even wear out, leading eventually to complete failure.


The breakdown of the blower belt while the vehicle is in operation will lead to minor problems like less engine performance or rich fuel situations to serious mechanical issues like cylinder head hardware failure to break down of connecting rods.

For your engine to perform better, ensure maintaining the high-performance supercharger pulley. Here are listed some key symptoms that’ll warn the owner of the supercharged engine about the problem with the supercharger belt. Let’s have a look at these symptoms:


  • Ticking sound coming from the motor: It is very much difficult to identify whether the belt is in better working condition or there is any need for it to be replaced that too without frequent visual inspection. Therefore, it is necessary to keep a note on the very subtle warning sign is caused by the frayed supercharger belt that is hitting the belt guard or another high performing supercharger pulleys that in return helps to power the supercharger. The sound then originated is similar to a knocking engine or a loose rocker arm and the volume will increase as the blower accelerates.
  • Decreased fuel efficiency: Some high-end power cars are powered by superchargers that use a supercharger belt to turn the rotors inside to produce higher air volume that can further be mixed with more fuel efficiency to produce more horsepower. When the belt becomes thin and breaks, the supercharger stops spinning, leading to the wastage of tremendous amount of fuel.
