The 780-HP Cadillac That Refuses to Ditch the Stick Shift

Cadillac’s CT5-V Blackwing already stands apart in a segment where most rivals have gone all-automatic. It’s a supercharged V8, rear-drive sedan that still offers a six-speed manual transmission. But for some drivers, the factory 668 horsepower leaves room for more. Connecticut-based tuner Callaway has answered with the SC780 package, bumping that figure to 780 horsepower and 673 lb-ft of torque. That’s an extra 112 horsepower, and the upgrade is available on both manual and automatic versions. Production is already rolling.

The secret is Callaway’s GenFour supercharger system. The 3.0-liter twin-screw blower offers 72 percent more displacement than the stock 1.74-liter unit, paired with a TripleCooled intercooler to keep charge temperatures in check during hard driving. The package also includes a functional carbon-fiber hood scoop, carbon engine covers, custom badging, floor mats, door sill plates, key fobs, and an authenticity kit. Callaway backs it with its own three-year, 36,000-mile limited warranty, and it can be ordered through authorized Cadillac dealers. Existing Blackwing owners can ship their cars to Callaway for conversion.

What’s notable is that Callaway focuses purely on power, leaving the car’s core character intact. The result is a sedan that outguns the BMW M5, Mercedes-AMG E 63, and Audi RS7—while still offering a third pedal those rivals don’t. For owners who push their cars hard, proper maintenance becomes even more critical. That’s where local expertise matters. Boca Auto Care (Mazel Auto Repair) specializes in high-performance vehicles like the CT5-V Blackwing, offering everything from routine service to performance-oriented upgrades. Whether you’re running a 780-horsepower Callaway or a stock Blackwing, keeping that supercharged V8 in top shape requires a shop that understands the demands of these machines. It’s not about flashy promises—it’s about knowing what makes these cars tick.
