Dodge Turned the SIXPACK Charger Into 750-HP Drift Cars: What They Teach Us About Boost, Fuel and Drivetrain Limits
Dodge did not wait long to prove that the new twin-turbo SIXPACK Charger is more than a straight-line street car. Two production-based 2026 Charger Scat Packs were transformed into purpose-built drift machines for Roadkill Nights, and the builds are a surprisingly useful lesson for anyone planning a serious turbocharged street or race car.
According to Performance Racing Industry, both cars began as 550-horsepower Charger Scat Packs powered by the high-output 3.0-liter twin-turbo SIXPACK engine. The teams then converted the factory all-wheel-drive, automatic configuration to rear-wheel drive, installed competition manual transmissions and pushed the combinations into the 750-horsepower range.
The headline is the power number. The real story is everything that had to change around the engine to make that power useful.
750 horsepower is a system, not a boost setting
It is easy to look at a modern turbo engine and assume the path to another 150 or 200 horsepower is simply more boost. These Charger builds show why that thinking falls apart quickly.
The two cars used different forced-induction strategies. PRI reports that the BOOST Coupe moved to a high-output single-turbo arrangement, while the RPM four-door retained a heavily modified twin-turbo setup. Both cars received custom intake and exhaust systems, MoTeC engine management, upgraded fuel-delivery hardware and rear-mounted cooling systems.
That is the pattern we see on serious builds regardless of badge: airflow, boost control, fueling, heat rejection, calibration and driveline strength all have to advance together. Increasing compressor flow without supporting the rest of the system only moves the failure point somewhere else.
Boost control matters just as much as the turbo itself
A larger turbo can make more airflow, but the wastegate and control strategy determine whether the engine can manage that airflow repeatably. On a high-output setup, poor boost control can create overshoot, unstable pressure or inconsistent power delivery. That is annoying on the street and potentially destructive at sustained load.
The Charger drift builds used Turbosmart hardware as part of their forced-induction packages. SMG carries the same types of components used throughout serious turbo systems, including the Turbosmart 3-Port Boost Control Solenoid, Turbosmart eB2 4-Port Solenoid and Turbosmart RacePort BOV Controller Kit.
Those links are examples of the component categories involved in a properly engineered turbo system. They should not be assumed to fit the 2026 Charger SIXPACK unless Turbosmart or another manufacturer publishes confirmed application data. On a new platform, verified fitment matters.
Fuel delivery becomes the limit sooner than most people expect
More boost means more air mass. More air mass requires more fuel, and direct-injected engines can run into high-pressure fuel-system limits even when the in-tank side still looks adequate on paper.
PRI notes that the Charger builds used custom fuel-delivery components. That is an important clue for anyone chasing a similar percentage increase in output. A fuel system should be sized around actual mass flow, fuel type, target pressure and injector duty rather than a generic horsepower sticker.
The same principle applies across the platforms SMG supports. Whether the combination uses a high-flow in-tank pump, upgraded high-pressure pump, larger injectors or supplemental port injection, the answer should come from data. Our recent guide, Stop Tuning by AFR Alone: Lambda, E85 Content and Wideband Errors Explained, gets into why fuel composition and lambda matter when the demand starts climbing.
SMG stocks a broad range of DeatschWerks fuel-pump and fuel-system hardware for supported applications, along with platform-specific GM, Ford and other performance fuel systems. Again, the lesson from the Charger is the architecture, not a claim that an existing catalog part automatically fits a brand-new SIXPACK application.
Heat management is part of horsepower
Drifting is brutal on a powertrain because the engine stays loaded while vehicle speed and available cooling airflow vary constantly. The teams did not leave the factory cooling layout untouched. Both cars received rear-mounted cooling systems as part of the conversion.
Street cars usually do not need that kind of redesign, but the principle is the same. Charge-air temperature, coolant temperature, oil temperature and transmission temperature affect repeatability. A car that makes a big number on the first pull and loses power on every pull after that is not a finished combination.
This is one reason dyno validation matters beyond a single peak horsepower figure. At North Texas High Performance, a build can be loaded and monitored on the Mainline ProHub so fueling, boost behavior, temperature and power delivery can be evaluated together instead of judging the car from one screenshot.
The driveline may become the real horsepower limit
The most useful takeaway from the whole project may be that the engine was not the only thing dictating usable power. The factory Charger begins as an all-wheel-drive automatic. These cars were converted to rear-wheel drive and manual transmissions, with custom bellhousings, clutch hardware, heavy-duty driveshafts, competition axles and quick-change rear differentials.
That is what happens when power and intended use change dramatically. Torque has to travel through every component after the crankshaft. Transmission capacity, clutch capacity, driveshaft speed, axle strength, differential temperature and wheel hop all become part of the equation.
The takeaway for a street build is not that everyone needs a race transmission or quick-change rear. It is that the weakest link should be identified before the power level is doubled. A well-planned 650-horsepower combination that survives years of use is a better build than a 750-horsepower dyno sheet attached to a car that constantly breaks.
Power is useless if the chassis cannot use it
Dodge's drift cars also received substantial chassis work: drift-specific suspension, increased steering angle, hydraulic handbrakes, upgraded braking hardware, competition wheels and tires, roll cages and safety equipment. Those changes are obviously aimed at professional drifting, but the broader message applies to street and track builds too.
Once power rises, the chassis has to keep up. Tire selection, suspension geometry, dampers, alignment, braking and differential behavior determine whether the extra horsepower makes the car faster or simply harder to control.
That is why SMG has been pushing the idea of complete combinations instead of disconnected parts lists. Yesterday we covered why brake stiffness, heat capacity and pad selection matter more than piston count. The same systems thinking applies here: horsepower, braking and chassis setup all have to match how the car will actually be used.
What this means for the new Charger aftermarket
The SIXPACK Charger is still a very new platform, so owners should be cautious about assuming that universal turbo hardware or older Dodge parts are direct fits. But purpose-built 750-horsepower examples appearing this early are a strong signal that tuners and manufacturers are already probing the platform's limits.
The most interesting part is not whether a street owner should copy these two drift cars. Most should not. The interesting part is that the new Charger has already been forced well outside its stock operating envelope, and the supporting changes required to do it are exactly the same categories that matter on every serious boosted build: controlled airflow, sufficient fuel supply, heat management, calibration, driveline capacity and chassis control.
That also fits the bigger trend we covered in SEMA's 2026 outlook for gasoline-powered performance. New internal-combustion performance platforms are still giving the aftermarket fresh hardware to engineer around, and Dodge's twin-turbo SIXPACK is now one of the most interesting examples.
Build around the goal, then validate the combination
If you are planning a boosted build, start with the use case and target power before buying parts. Decide how the car will be driven, what fuel it will use, how much heat it must survive, what the driveline can tolerate and how the boost will be controlled. Then select the turbo, fuel system, wastegate, bypass/blow-off hardware and calibration strategy as one package.
