The Chevy Tahoe, Chevy Suburban, and GMC Yukon full-size SUVs offer loads of practicality and cabin space, but when it comes to straight-line speed, some customers may be left wanting. That’s where Callaway Cars comes in with its new SC520 supercharger package.
For those readers who may be unaware, Callaway has built a reputation for churning out high-performance GM vehicles over the last 45 years. Now, the Connecticut-based specialist is supercharging the latest Chevy Tahoe, Chevy Suburban, and GMC Yukon to produce a whopping 520 horsepower and 490 pound-feet of torque.
The new Callaway Cars SC520 package is designed to fit Chevy Tahoe, Chevy Suburban, and GMC Yukon models equipped with the naturally aspirated 5.3L V8 L84 gasoline engine, which is rated from the factory at 355 horsepower at 5,600 rpm and 383 pound-feet of torque at 4,100. That means the blower adds upwards of 165 ponies and 107 pound-feet of twist to the equation.
The main party piece of the package is the Gen Three TVS R2650 supercharger, which features TripleCooled Intercooling, as well as an internal bypass mechanism that diverts airflow during low load to provide “practically unchanged” fuel economy compared to the atmospheric setup. Further complementary upgrades include Callaway’s high-flow intake system and low-restriction stainless-steel dual exhaust system with quad tips. Callaway also uses its bespoke CalCal engine control components and calibration to provide 50-state emissions compliance and unconstrained warranty retention.
In addition, the Callaway SC520 package tosses in several aesthetic upgrades, such as a carbon mid-engine cover, aluminum door sills, key medallions, chrome exterior badging, and authentication plaques. Critically, the package also includes a 3-year / 36,000-mile limited warranty.
Optional equipment includes things like 20-inch wheels, a billet pedal set, an Alcantara horn cover, and black exhaust tips. Pricing for the package starts at $24,995.
