Superchargers are no big secret to making horsepower. In fact, their use on production cars dates all the way back to the 1920s. In today’s market there are many types of superchargers and a multitude of kits for the 2005-2013 Corvette. Clearly the willingness of Corvette owners to modify their cars, combined with the desire to keep up with new Vette models (such as the 7.0L Z06 and the supercharged ZR1) as well as foreign competitors has inspired many to purchase various methods of forced induction. Due to the very tight packaging constraints, many consider positive displacement blowers, such as the Eaton TVS2300 on the ZR1, to be superior on most street cars and others maintain that the compromises are worth it to install a turbo kit. However, yet a third avenue combines the best of both worlds, providing the best thermal efficiency and a high ceiling for producing horsepower – centrifugal superchargers. Yet even in this market, there exist many choices. Ours was ProCharger.

From the very beginning we’ve wanted to add boost to our daily-driven 2005 Corvette Z51, and we went through the merry-go-round of options. The goal has been to equal or surpass a ZR1 without compromising reliability. To that end we called ProCharger, with whom we have had nothing but great experiences. The ProCharger C6 kit has undergone some revisions lately, mainly when they designed the LS3 version, to reduce belt slip – the potential bane of any centrifugal supercharger kit. The D-1SC tuner kit provided all of the power potential and extras we would want to make the system reliable as possible during some hard miles, while leaving fuel system upgrades up to the installer. Speaking of the installer, that is another key to making this setup reliable and driveable. The one-year-only E40 ECM presents some interesting challenges for adding boost, and thankfully Torq Speedlab knew just how to overcome them. Torq co-owner and calibrator Paul Meister drew up a plan that would remedy our fueling and metering issues, allowing the LS2 to run and drive like stock, but with a whole lot more kick. Follow along for Part 1, and stay tuned for the next installment.
