Before the C6 Corvette ZR1 was released, Pratt & Miller Engineering decided to take performance of the Corvette to new heights with the C6RS performance package. And being that Pratt & Miller is the engineering force behind Corvette Racing, the C6RS has an unrivaled performance pedigree, and Motorweek was lucky enough — albeit some time ago — to examine one.
What’s perhaps the most staggering feature of the C6RS has to be the engine. This particular unit features an 8.2L (!) freely breathing Katech V8 engine — the same company that currently makes the engines for the Cadillac Racing team — producing a ferocious 600 horsepower and 600 pound-feet of torque, while sounding nothing like a traditional GM Small Block, and more like an American Le Mans racing car.
The engine itself was an option that cost nearly $40,000 on its own. But judging by the C6RS’ website, it’s unlikely that such an engine is even available these days, with the spec sheet listing a supercharged LS7 tuned by Thompson Automotive which produces an even more substantial 750 hp and 820 lb-ft.
The rest of the package, which in this case features revised seats and steering wheel, a widened body, multiple aerodynamic improvements, brake upgrades, a suspension lifting system, and carbon fiber paneling — costs over $100,000, plus the donor Corvette Z06 needed to make it all possible. That’s serious money, but seems well worth it, and will surely stand out among other tuner Corvettes from the likes of Callaway, Lingenfelter and Hennessey, all of which have cemented themselves as leaders in performance. That’s saying something.
