Callaway Cars is offering performance truck enthusiasts a chance to upgrade their 2019- through 2021-model-year Chevy Silverado with the Callaway SC602 Signature Edition package, which ups output in the popular pickup nameplate to over 600 horsepower. Now, the latest Callaway-tuned Chevy Silverado is getting put to the test alongside the Dodge Ram TRX in the following video feature.
The video clocks in at 6 minutes, 16 seconds, and includes a number of acceleration tests, including a drag race from a dig, a rolling drag race, a 0-to-60 mph sprint, and a 0-to-100 mph sprint.
To give the Chevy Silverado a fighting change against the Dodge Ram TRX, Callaway installed a bevy of new gear, starting with a GenThree TVS R2650 supercharger system and TripleCooled intercooler for the 6.2L V8 L87 gasoline engine. Fresh air is directed through a new high-flow intake, while spent gasses are expelled through a low-restriction stainless steel dual exhaust system with quad tips. Following Callaway’s bespoke engine control calibration and tuning, the setup is good for a claimed 602 horsepower at 6,000 rpm and 560 pound-feet of torque t 4,500 rpm.
Of course, the Dodge Ram TRX is no slouch either, throwing down a heady 702 horsepower at 6,100 rpm and 650 pound-feet of torque at 4,800 rpm thanks to its Gen III 6.2L V8 Hemi, which is also supercharged.
Although the Chevy Silverado is in the hole by 100 horsepower and 90 pound-feet of torque, there are a few important differences to point out here. For example, the transmissions and drivetrains are a notable point of departure, with the Chevy Silverado running a 10-speed automatic transmission, and the Ram TRX running an eight-speed automatic transmission. Rear axle ratio on the former is 3.42:1, while the latter gets a ratio of 3.55:1. There’s also a huge weight difference, with Callaway rating the tuned Chevy Silverado at 5,820 pounds, and the Ram TRX at 7,080 pounds.
