Tips to Find Out a Bad or Failing Supercharger Belt

The supercharger belt is used to force more air into the fuel intake manifold to provide the car with more horsepower.

Moreover, the supercharger belt is so important to the efficient operation of a supercharged engine that it is vital to perform routine servicing of the belt.

However, like every other mechanical part, the supercharger belt eventually wears out and ultimately leads to complete failure.

The breaking of this supercharger belt can cause minor issues like low engine performance or increased fuel consumption to critical issues like cylinder head hardware failure & breaking connecting rods.

Here are the warning signs which will let you know that the supercharger belt has malfunctioned.

Abnormal sound from motor

One of the hardest things to diagnose without frequent visual inspection is when a supercharger belt is wearing out and needs to be replaced.

However, one of the earliest warning signs of this issue happening is when a frayed supercharger belt hits the belt guard or other pulleys that help to power the supercharger.

Moreover, this sound will be similar to a knocking engine or a loose rocker arm and will increase in volume as the blower accelerates.

Whenever you experience this sound, then you need to stop the car and inspect the supercharger belt for any wear and tear.

Lower fuel efficiency

Nowadays, high-end performance cars are powered by a supercharger belt to turn the rotors inside which will produce higher volumes of air and this, in turn, will mix with more fuel to produce more horsepower.

When the supercharger belt breaks, the supercharger will stop spinning, however, unless the fuel is manually trimmed or adjusted by electronic fuel injection, raw fuel will not burn in the combustion chamber.

This leads to lower fuel efficiency in your car and there is a waste of a tremendous amount of fuel.

If you have a broken supercharger belt, it is always advised to stop your car and contact a mechanic to replace the belt immediately.

Immediate loss in power

Whenever the supercharger belt breaks, it stops spinning the supercharger which affects the flow of air into the manifold and this, in turn, drastically reduces the amount of horsepower.

However, the owner of a car which has a supercharger belt will be able to recognize the symptoms associated with a broken or worn supercharger belt.

Whenever you notice any of the above warning signs, it is best to stop driving the car and ensure the supercharger belt is replaced immediately.
