    Over the years the power levels of Corvette C6's with ProCharger superchargers have been pushed from 550rwhp to a mind-blowing 1,491rwhp! (video)

    A little while back we released our new "Race" air-to-air intercooler, which has already been destroying the dyno rollers to the tune of 1,457rwhp!(video)

    With these big power cars becoming the norm nowadays, ProCharger has added a Stage II C6 Corvette system to the product lineup. Read on to find out the differences between the Stage II system and the HO system.


    With big power comes the need for big airflow to the blower. The Stage II Corvette system will come with a 4.00" inlet tube combined with a high-flowing, reusable air filter.

    The #1 enemy of any high HP supercharger system is belt slip. The longer the drive belt is, the more it will grow as power is applied to it. To keep the ProCharger drive belt short, we have incorporated a direct drive into the Stage II system. By adding a direct drive belt system to the ProCharger, we are able to decrease the overall length of the belt by over 40%, creating an ultra-strong grip.



    ProCharger also made sure that the accessories were given a strong OEM spring loaded tensioner. Using a spring loaded tensioner ensures that the accessories will have the proper belt pressure applied to them as the belt wears and grows over time.

    To make installation of the accessory belt easy, we have also included an extra "boss" built into the bracket to allow for better leverage to release the tensioner. Once tension is off the belt, the belt can be easily slipped over the alternator pulley.

    The Stage II system will come standard with a 6 rib blower drive belt running off the factory balancer. Upgrades to wider belts will be available soon with the addition of an aftermarket balancer.
