      Very interested in this charger , what is the recommend cam, injector combinations are needed with this system I've already upgraded my throttle body to 70 mm and map Thanks

      • This Paxton Novi 1220SI Supercharger System is designed to be used with the stock injectors and other stock components. You can use larger injectors, throttle body, and other components however, they would need to be tuned for. Since there are limitless combinations, we would recommend speaking to your tuner if you plan to add additional components.

      • Hello, Your vehicle will need custom tuning in order to run properly and its best. A supercharger makes significant changes to the way any engine runs and it will need to be tuned accordingly.
