When Ford dropped the 2024 Mustang Dark Horse, we knew we had to make it louder, faster, and far more lethal. Enter: the Lethal Performance Edition Gen 6 3.0L Whipple Supercharger Kit. This isn't just another boosted S650—it's a purpose-built predator engineered to hunt records both on 93 octane and full E85. Every component, from the KPM 1500hp fuel system to the RSA-built 10R80, was selected for durability, repeatability, and raw power.
In nearly stock trim—just blower, axles, tires, and a catback—we blasted a 9.76 @ 138mph. With the full arsenal engaged and E30 in the tank, the car dropped jaws with a 9.28 @ 149mph. But we weren't done. On E85 with a smaller 3.50" pulley and 1300lb injectors, this beast cranked out an absolutely ridiculous 1049.5 rwhp and 751.4 ft-lbs—all while retaining factory headers and full interior. With the addition of a 3.25" pulley we took it to the strip and joined the 8 second club with an 8.87 @ 154! That's the kind of no-compromise performance we chase at Lethal. No gimmicks. No fluff. Just a fully streetable build that throws down harder than anything in its class.

Lethal Performance's 2024 Mustang Dark Horse isn't just a new-gen S650—it's a showcase of what happens when cutting-edge supercharger tech meets proven track-tested hardware. At the heart of this build is our Lethal Edition Gen 6 3.0L Whipple Supercharger Kit, delivering serious airflow through Whipple's new competition open-air box and carbon fiber intake tube. To keep the boost steady under load, we've equipped a Griptec 3.5" pulley paired with the Whipple 10-rib Race Belt System and a 20% overdrive balancer. The fueling is handled by a KPM 1500hp return-style system, ensuring consistent pressure whether we're on 93 octane or an E30 blend.
On the drivetrain side, we've reinforced the factory layout with a built RSA 10R80 transmission, Circle D converter, QA1 carbon fiber driveshaft, and Driveshaft Shop Nemesis axles to handle serious torque. While the suspension remains stock (for now), the car hooks thanks to sticky Mickey Thompson ET Street R drag radials and Forgeline wheels. It exhales through a deep-sounding AWE SwitchPath catback for ideal flow and tone.
The results? With just the supercharger kit, AWE exhaust, and drag radials, we clocked a 9.76 @ 138 MPH on 93 octane, making 734rwhp. A bit of VP Octanium in the tank pushed it to 791rwhp. Once we dialed in the smaller pulley, added the 20% lower, and fed it an E30 blend, the Dark Horse ripped a 9.28 @ 149 MPH with a killer 1.33 60-foot. But the real party started when we switched to E85—with a 3.50" pulley and 1300lb injectors, this monster put down 1049.5 rwhp and 751.4 ft-lbs at 20.7 psi peak boost, clocking a 9.06 @ 152, still on factory headers. In an attempt for 8's we threw on a 3.25" pulley and sent our Mustang Dark Horse down the strip to run a 8.87 @ 154! This car isn't just fast for a street build. It's redefining what "bolt-on" means for the next generation of Mustang.
We weren't satisfied with "just" running 9.28s on E30. So we loaded up a Shoemaker Performance custom E85 tune, swapped to a 3.50" upper pulley, added 1300lb Injector Dynamics injectors, and sent it to Area 51 Motorsports' hub dyno. The result? An absolutely ridiculous 1049.5 rwhp and 751.4 ft-lbs at 20.7 psi peak boost—still on factory headers.

Want to see what it takes to push a stock-engine 2024 Mustang Dark Horse into the 1000+rwhp club? Our video series covers every step — from bolting on the Lethal Edition Whipple 3.0L supercharger to track passes, a new fuel system, and real-world results. Whether you're chasing the same setup or just here for the tire smoke, this playlist breaks down the build with no fluff, just fast.
The car features the Lethal Performance Edition Gen 6 3.0L Whipple Supercharger Kit, which includes the latest high-efficiency rotor pack, a 150mm open air intake, and carbon fiber cold air tube. It's paired with a GripTec 3.625" pulley and Whipple's 10-rib belt system for maximum belt grip at high boost levels.
A KPM 1500hp return-style fuel system is installed to deliver consistent fuel pressure across a range of boost levels. This system is essential for safely running higher output on an E30 blend.
On 93 octane pump gas with VP Octanium, the car made 791rwhp and 619rwtq. With a pulley change, 20% lower balancer, and an E30 fuel blend, we achieved a best pass of 9.28 @ 149mph (no dyno was done for that setup, but estimated output is well into the 850+ rwhp range).
To safely run E85 and achieve 1049.5 rwhp, we upgraded to 1300lb Injector Dynamics injectors, installed a 3.50" Griptec upper pulley (smaller than the previous 3.625"), and had Shoemaker Performance create a custom E85 tune. The setup produces 20.7 psi peak boost and still uses factory headers—proving there's even more left in this combination.
No. The car runs an RSA-built 10R80 automatic transmission paired with a Circle D torque converter, designed to handle the added horsepower and torque under aggressive dragstrip launches.
Surprisingly, the car still uses the factory suspension setup. Despite that, it has recorded consistent 1.3-second 60-foot times thanks to the drivetrain setup, tire choice, and well-optimized launch control tuning.
We swapped in Driveshaft Shop Nemesis axles and a QA1 carbon fiber driveshaft for increased strength and reduced rotational mass. These parts ensure reliable performance under the high-torque launches this car is built for.
