The folks over at Autoweek are now officially among our most envied contemporaries; they recently had the opportunity to take two Callaway Chevrolet models through their paces on the streets of Orange County. One was the 627 horsepower Callaway Corvette SC627 (pictured), and the other was a completely bonkers 652 horsepower Callaway Camaro SC652, born of Chevrolet’s Camaro Z/28.
In a sense, modifications to both of these cars was fairly minimal; deeming the suspensions of both the C7 Corvette and the Camaro Z/28 near enough perfect, Callaway Cars’ engineers instead focused entirely on power output. And what does one do when they want to ignite a fire? They blow on it.
The “blowers” in question are the same for both the Z/28’s 7.0 liter LS7 and the C7’s 6.2 liter LT1: Eaton 2300 TVS superchargers. That 2300 in the name refers to the cubic-centimeter displacement of the blower, and it represents a spot of good fortune for Callaway; the company had already made use of the same supercharger on the previous-generation Z06’s LS7, to great effect.
The result in both the Callaway Camaro Z/28, and the Callaway Corvette C7, is tremendous. The former will blast to 60 mph in 3.7 seconds, and run the quarter-mile in 11.5 at 124 mph. The latter struts to 60 mph in 3.4 seconds, running the quarter in 11.0 at 126 mph. That means sizable gains for both models over stock.
Ah, but the price. The full package for the Camaro Z/28 runs at approximately $20,000, bringing the total cost of the Callaway Camaro SC652 up over $96,000. More fortuitously, the complete package to make a Callaway Corvette SC627 costs $18,000, meaning the full car starts at around $74,000.
That’s a good thing, too, as we don’t anticipate that Callaway would sell many examples of the Corvette SC627 if it cost as much as a new Z06 while making less power. All in all, we have to say that these two Callaway supercharger packages sound like two ideal kits to get the most out of your 2015 Camaro Z/28 or 2015 Corvette Stingray.
