To adjust the output of the HKS GT Supercharger, you can do so by adjusting the supercharger RPM depending on the engine specification. When using the HKS GT Supercharger, the maximum RPM of the SUPERCHARGER must be within the maximum allowable RPM of each unit. Use the following formula to calculate the SUPERCHARGER's maximum RPM.

Changing the pulley size will increase or decrease the amount of RPM, therefore also increasing or decreasing the effective power that the GT Supercharger will produce.
