Callaway Cars has pulled the sheet off of something that’s been in the works for years: a supercharged C8 Corvette Stingray. And did so at the 2022 Corvettes At Carlisle event in Pennsylvania, taking place from August 25-28.

Atop of the LT2 V8 engine sits a 2.3L TripleCooled supercharger, featuring an in-house design witha roots-type Eaton TVS 2300 rotors, with final performance numbers coming in at the end of testing. Callaway also tells us that they’re evaluating a 2.65L booster as well. Yes, the package isn’t quite done yet, but Callaway nevertheless wants to get the buzz going on this supercharged C8 Corvette Stingray, and is taking $1,000 deposits from anybody who wants one. On social media, the Old Lyme, Connecticut company says that the package will land in “the low 20’s installed.” Say you got a base 2023 Corvette Stingray at MSRP (hypothetically, let’s just say you did). That would put you with a supercharged C8 somewhere in the $85k-$90k range before any options. Maybe you want something different than a factory Z06? This ought to do it.

Here’s where things get very interesting. Callaway also says that it has “access to calibrate without using a piggyback system” on its supercharged C8 Corvette Stingray. Does that mean GM, which has an incredibly close relationship with Callaway Cars, let the company in on tuning the Stingray’s notoriously encrypted ECU? We’ll have to uncover more details to be sure, but as you can see from the photos, there appears to be no extra control module that’s visible. Other solutions have so far required a sort of piggyback controller, or an interceptor controller that convinces the factory electronics that there is no supercharger, operating within an acceptable framework.

Production of the supercharged C8 Callaway Corvette is said to begin in early 2023, and will be sold through its official network of licensed Chevrolet dealers. Just as well, these Callaway Corvettes can be serviced at those same dealerships. Like other Callaway GM builds, this supercharged C8 is backed by a three year/36,000 mile GM powertrain warranty, and an optional five-year/60,000 mile service contract. You won’t find another third party matching GM’s warranty.
