Fitting instructions:

The supercharger pulley replaces the pulley on the vehicle. It has to be picked up by the supercharger. This is usually achieved by warming up and carefully cutting open the old pulley.

The upgrade pulley should be heated up. It also helps to shrink the Supercharger's shaft by using cold spray or storing the SC in a cool place. The new pulley must then also be put on.

It is not necessary to make any changes to the housing of the Supercharger. There is also the option of performing a further upgrade in combination with the lower belt pulley. We are happy to help!

Safety instructions

We clearly point out that this is a tuning part for which there is no general operating permit (ABE) or a TÜV certificate. Installation is at your own risk. There is only liability in the amount of the purchase price and in the case of demonstrably defective goods. We would like to point out that the compressor should be dismantled for the conversion and should not remain in the vehicle, as there is an acute risk of fire in the vehicle due to the necessary heating of the compressor.
