Muscle cars have always invited modification. That’s because it’s in an automotive enthusiast’s nature to be power-hungry and to tinker. So if we’re provided with a go-fast template, we’ll inevitably start asking: What happens if we turn it up a little?
The new Dodge Charger Scat Pack lets tuners answer that question in novel ways. Because under its long hood sits not a typical V-8 but the SIXPACK, a potent 3.0-liter twin-turbocharged inline-six. Though this engine offers up to 550 hp and 531 lb-ft of torque in High Output (HO) trim, and 420 hp/468 lb-ft in an “entry level” (SO) trim, for optimizers like us those are merely opening bids.
This motor’s clean-sheet design, combined with its mechanical robustness, invites fresh thinking on how to increase output. Beyond this, the new gas-powered Charger’s widebody proportions, independent suspension, and rear-drive (and/or all-wheel-drive) architecture create a highly advanced starting point for your personal build. The SIXPACK is thus perfectly poised to become Dodge’s new tuner playground.
Six Cylinders, Serious Intentions
The SIXPACK comes stock with impressive dyno sheet specs. But in the quest to shatter factory performance boundaries, the hardware with which it’s built matters just as much. High-flow 54mm Garrett twin turbochargers feed the engine, with the HO variant calibrated to allow up to 30 psi of boost. Much like the R/T, the engine is tuned to unleash its peak torque starting at 2500 rpm, ensuring you have the immediate muscle to power through the curves.
For tuners, all of this is tantalizing. The question becomes how much output the engine, fueling system, transmission, cooling, and calibration can ultimately support, and how effectively that power can be put to the ground.
There’s only one real way to find out—dig in and build. And the Charger Scat Pack has already provided a preview.

The Grudge Match Experiment
At a recent Roadkill Nights event, Dodge turned tuner speculation into a controlled experiment with its Direct Connection Grudge Match.
Eight online and influencer automotive builders were handed essentially the same starting point: a 550-horsepower Charger Scat Pack. From there, the competitors were free to modify, tune, and test their cars as they saw fit. Then they lined up to race, to see whose combination worked best. The results were exactly what you'd hope for from an experiment like this, with a modified HO producing 1000 horsepower taking the win and another build producing an astonishing 1064 horsepower.
Consider the significance of those numbers. These weren't blank-sheet drag cars. They all started with the same basic SIXPACK engine available to customers, right off the dealer floor.
The Grudge Match vehicles demonstrated the power madness modern tuners can unleash with a factory turbocharged platform. More important, they showed the sort of sky-high ceiling that makes horsepower aficionados start reaching for their tools, hoping to one-up whoever’s build came before.
Commanding the Limit
Straight-line acceleration is only one variable in the modern muscle-car equation. The Charger Scat Pack's four-wheel independent suspension gives builders something previous generations of muscle cars often lacked: a chassis designed to maintain control when the pavement isn’t drag-strip straight.
Up front, multilink units utilize forged aluminum connectors and negative-camber induction to maximize traction and structural strength. At the rear, the integral link setup is engineered to provide body control and steering feel at high cornering speeds.
The Charger’s independent suspension also allows the chassis to manage weight transfer and tire loading with far more sophistication than traditional live-axle muscle cars that defined much of Dodge's performance heritage. The result is a platform capable of balancing considerable power with the precision necessary to control it. This combination becomes particularly interesting when the Charger is asked to drift, something it can readily accomplish in RWD mode, accessible at the push of a button.
The key element the Charger thus provides to tuners is balance. Doubling the number of horses doesn't automatically make a car faster or more entertaining. The magic happens when power, tires, suspension, alignment, differential behavior, steering response, and driver inputs work in harmony. That's where a properly factory-engineered chassis becomes valuable to the modifier. Working from such a solid and dependable baseline, the builder gets to concentrate their efforts on making the car better, faster, more controlled, or more outrageous.
Widebody, Wide Open
The Charger Scat Pack brings the stance. Its widebody frame provides proper modern muscle presence. It is low, broad, and properly planted, with refined proportions that echo the visual language of classic American performance cars without slavishly pretending it's still 1969.
What’s more, its resolute thickness isn't there just for nostalgia’s sake, or for trapping thirst on social media. The flaring bodywork creates ample space for whatever kind of wheel-and-tire package a builder desires. Want to maximize rear grip? Build for it. Want a chassis that can transition into controlled oversteer? Have at it. Looking to include an aggressive staggered setup? Choose accordingly.
That's part of what makes the Scat Pack such an intriguing platform for tuners. There isn't one correct configuration. The Charger can be individually tailored to the person behind the wheel.
