A new V8-powered F-150 hits the dyno and drag strip, revealing real horsepower and speed.
The latest Ford F-150 equipped with a naturally aspirated V8 recently went through dynamometer testing and drag-strip runs—and the results surprised many observers. Engineers and testers compared the numbers with factory specifications and explained why the truck’s top speed remains electronically limited.
In the pickup world, it’s rare for a production truck to spark serious technical interest, but this particular F-150 has done exactly that. Specialists from Stid used the truck as a development platform to test components and explore ways to make the full-size pickup quicker and more powerful.
The starting point was a standard SuperCrew model with four-wheel drive, a 5.0-liter naturally aspirated V8, and the 10R80 10-speed automatic transmission. Although Ford Motor Company doesn’t officially call the engine “Coyote” in the F-150 lineup, enthusiasts are well aware of the engine’s reputation. The truck used for testing also included the factory towing package, the 501A equipment group, and the black appearance package, giving it both practical capability and a more aggressive look.
The first step was the dyno test. Running on regular 87-octane gasoline, the pickup produced 322 horsepower at the wheels in fifth gear. Testers noted that higher-octane fuel and ideal testing conditions could potentially increase that figure. Fifth gear was used because of transmission limitations: seventh gear—closer to a perfect 1:1 ratio for dyno measurements—can’t be accessed due to the vehicle’s speed limiter. Based on their calculations, the engineers estimate the engine would produce about 335 wheel horsepower in seventh gear, which aligns closely with the factory rating of roughly 400 horsepower at the crank once typical drivetrain losses of about 20% are considered.
After the dyno session, the truck moved to the drag strip for quarter-mile testing. With four-wheel drive engaged, it completed the run in 14.906 seconds. Switching to rear-wheel drive delivered an even better result: 14.74 seconds with a trap speed of 95.88 mph. For a production pickup powered by a naturally aspirated V8, that’s an impressive figure by industry standards.
Top-speed limitations are another interesting aspect of the truck’s setup. Despite the capability of the engine and transmission, Ford electronically limits the F-150 to about 106 mph. The reason is primarily safety: the truck’s high center of gravity, suspension setup, and tire design make sustained high-speed driving risky for a heavy pickup.
For comparison, the off-road-focused Ford F-150 Raptor with the EcoBoost V6 is limited to around 120 mph, while versions equipped with 37-inch tires or the Predator engine are capped at roughly 114 mph.
Even the extreme Ram 1500 TRX—powered by a 777-horsepower supercharged V8 producing about 680 lb-ft of torque—is electronically limited to around 118 mph. In that case, the restriction largely comes down to the truck’s Goodyear off-road tires with a T-speed rating. Thick sidewalls and aggressive tread patterns are designed for durability off pavement, not sustained high-speed loads, where overheating can eventually lead to tire failure.
