Now the Connecticut-based tuning shop has released full performance metrics for the Callaway Silverado Signature Edition – and we think readers will be impressed by the numbers this supercharged Chevy can put up.
The Callaway Silverado Signature Edition produces an SAE-certified 602 horsepower at 6,000 rpm and 560 pound-feet of torque at 4,500 rpm. These numbers are a bit different than the pre-dyno estimates Callaway posted on its site last month, which indicated the truck would produce around 585 horsepower at 6,250 rpm and 567 pound-feet of torque at 3,850 rpm. For reference, a stock Chevy Silverado equipped with the available 6.2L L87 V8 engine makes 420 horsepower and 460 pound-feet of torque.
Callaway’s internal testing also confirmed the truck will accelerate from 0-60 mph in just 4.3 seconds and complete the quarter-mile in 12.5 seconds at 113 mph. A stock Chevy Camaro SS, by comparison, can hustle from 0 to 60 mph in around 4.1 seconds and race through the quarter-mile in roughly 12.4 seconds at 115 mph. That means Callaway’s upgrade kit gives the big, heavy Silverado comparable straight-line performance to the much lighter Camaro SS. Not bad, Callaway. Not bad at all.
To recap, the Callaway Silverado Signature Edition is powered by the factory 6.2L L87 V8 engine, which is topped off with an Eaton TVS R2650 supercharger, a revised intake and a Callaway “Triple Cooled” intercooler setup. These specially tuned trucks also feature a full Callaway exhaust with quad tips, a carbon grille, chrome Callaway exterior badging, Alcantara interior trim and anthracite or satin black Callaway alloy wheels. Order books for the truck are open now, with Callaway encouraging interested parties to reach out by call or text at 860-434-9002.
