Sleeper in Plain Sight: The Gas Monkey Garage 800+ HP F-150
The pickup truck has pretty much always been seen as a work vehicle. In time it became more refined, more comfortable, and in some trim packages; even luxurious. The modern pickup bridges the gap between the everyday family vehicle and a truck to haul the kids bikes or materials for the latest home or garden project.
There’s been a growing movement though with modern pickups. Especially Fords. You may have seen videos of them beating Mustangs, Corvettes, and even Lamborghini’s on YouTube. People with fast cars are learning to be careful about lining up against a single-cab short-bed truck at a red light or messing with one on the freeway. This Gas Monkey Garage 2025 Ford F-150 4×4 is the ultimate testament to the surging “Muscle Truck” subculture, packing over 800 crank horsepower using a completely stock engine block and straightforward, bolt-on performance parts.
But It’s A 4×4?
The ‘4×4’ sticker on the bed may suggest to your brain that this can’t be a fast vehicle when in reality it’s signaling just how big of a threat that this truck may be. A 4×4 platform solves the severe traction issues of a rear-wheel-drive (RWD) truck. Sending that massive horsepower and torque through all four wheels gives the truck a tremendous traction advantage, allowing harder launches with far less wheelspin and helping keep the truck planted under acceleration.
This truck may be a 4×4, but it uses a complete RideTech Performance lowering suspension kit which lowers the chassis to drastically drop the center of gravity while also reducing the top-heavy body roll common to stock pickups. That helps give this F-150 the handling agility of a performance sports sedan. The RideTech geometry also locks the axle housing in place, keeping the sticky Mickey Thompson street-strip tires pressed firmly into the ground.
How Much Power Are We Talking About?
The 2024–2025 F-150 5.0L Coyote V8 is rated at 400 horsepower and 410 lb-ft of torque at the crank. This incredibly robust engine features a strong aluminum block, high-flow cylinder heads, and a dual-injection system (combining port and direct injection). This means the internal components—like the crankshaft, connecting rods, and pistons—are engineered so well that they can reliably handle massive amounts of forced induction without needing an expensive engine rebuild or aftermarket internal parts.
While the Gas Monkey Garage crew didn’t strap this exact single-cab F-150 to a chassis dyno before handing over the keys, the truck’s 800+ horsepower rating is a build specification based on the proven output of the Whipple supercharger system and the stock 5.0L Coyote V8. In other words, the 800+ HP figure represents the manufacturer’s and builder’s stated engine output rather than a published dyno result from this specific truck. The truck relies on Whipple’s official specifications for their Stage 2 3.0-liter twin-screw supercharger kit, which is mathematically rated to push the stock 5.0L Coyote V8 to an impressive 800 to 850 horsepower at the engine crankshaft. This crankshaft rating is the industry standard for how manufacturers and builders market vehicle power, showcasing the raw capability of the engine before any external variables interfere.
To translate that to the real world, readers should expect to see roughly 700 to 740 horsepower actually hitting the asphalt if the truck were placed on a roller dyno. In a heavy-duty 4×4 platform like this F-150, the modern 10R80 automatic transmission, transfer case, and heavy Weld racing wheels create about a 12% to 15% parasitic drivetrain loss. Even with the drivetrain taking its “tax,” the result is a brutally fast, street-legal weapon that delivers more than enough power to maximize all four tire patches under full acceleration.
Achieving The Power Gains
The beauty of the Gas Monkey Garage 800+ HP Ford F-150 4×4 is that the engine block was never opened. The massive leap in performance comes entirely from efficient bolt-on accessories:
| Component | Upgrade Installed | Function & Mechanical Impact |
|---|---|---|
| Forced Induction | Whipple Stage 2 3.0L Twin-Screw Supercharger | Compresses air into the intake manifold, multiplying the oxygen entering the cylinders to drastically spike power output. |
| Fuel Delivery | High-flow billet fuel rails & upgraded injectors | Ensures the engine receives enough fuel volume to safely match the massive rush of pressurized air from the supercharger, preventing a catastrophic lean condition. |
| Exhaust | Magnaflow Cat-Back System | Reduces engine backpressure, letting the spent exhaust gases exit rapidly to maximize supercharger efficiency. |
| The Result | ~800–850 Crank HP | A net gain of over 400 horsepower bolted directly onto a stock engine block. |
The Single-Cab Advantage (The Physics)
A factory Single Cab Short Bed (SCSB) 4×4 F-150 scales at roughly 4,500 to 4,700 lbs., stripping over 500 lbs. of dead weight compared to a bulky SuperCrew cab. In drag racing, shedding 500 lbs. is mechanically equivalent to instantly gaining 50 to 60 horsepower without touching the engine. In addition, the tight 122.5-inch wheelbase minimizes chassis flex, allowing for rapid weight transfer directly to the pavement compared to long-bed trucks.
The Single-Cab Advantage (The Physics)
A factory Single Cab Short Bed (SCSB) 4×4 F-150 scales at roughly 4,500 to 4,700 lbs., potentially shedding more than 500 lbs. compared to a similarly equipped SuperCrew 4×4. In a high-performance truck, that weight reduction has a significant effect on the power-to-weight ratio without requiring any additional horsepower from the engine.
At 800 horsepower, a 4,600-pound truck has a power-to-weight ratio of approximately 5.75 lbs. per horsepower. A 5,200-pound truck making the same 800 horsepower would be at approximately 6.5 lbs. per horsepower. The lighter truck therefore has roughly 12% less weight for every horsepower to accelerate.
The tight 122.5-inch wheelbase minimizes chassis flex, allowing for rapid weight transfer directly to the pavement compared to long-bed trucks.

About The Author
Growing up, my father always believed that every family needed a truck—there’s just something about having a vehicle capable of hauling anything at a moment’s notice. That philosophy stuck with me, and it’s been the foundation of my lifelong passion for Ford trucks.
While I’m best known for my work with Ford Rangers, I’ve owned a wide variety of Ford trucks over the years—including F-150s, F-250s, F-350s, and even larger rigs like the Ford Excursion, Ford Expedition, and a 1982 Ford Econoline Sportsmobile camper van. I’ve used these vehicles for everything from family transportation to towing car trailers and campers, and each one has fueled my love for Ford’s versatility and durability.
I especially enjoy the styling of 1970s and 1980s Ford trucks—the bold designs, rugged presence, and classic charm are timeless. Sharing my passion for Ford trucks, vans, and SUVs with other enthusiasts online brings me a great deal of joy, and it’s why I created Blue Oval Trucks.
This website is dedicated to helping Ford truck enthusiasts explore, learn about, and celebrate these incredible vehicles. While I share my expertise and experiences here, Blue Oval Trucks is an independent enthusiast site and is not affiliated with Ford Motor Company.
