Tork Tech offers numerous different size supercharger pulleys to add more power to your blower kit.

Our standard pulley is 3.25" in diameter. We offer custom sizes all the way down to 2.85". As an estimate, you can expect approximately 16# of boost with a 2.85" upper pulley on a car with stock heads.

Let us know what amount of power you are looking for and we will provide you with an estimate of what pulley size combination is required to achieve your goal.

Tork Tech also offers larger diameter crank pulleys also since we have a dedicated drive belt for our kits. This superior design allows for more boost with either a smaller supercharger pulley, or a larger crank pulley. There is no need to cut down the nose of your supercharger like other manufacturers have to do. By changing both the upper and lower pulleys we can provide you with enough overdrive on the blower to easily make in excess of 20 psi of boost.
