Watch Hennessey V8 Swap A Second-Gen F-150 Raptor: Video

Much to the chagrin of V8 fans, the second-gen F-150 Raptor comes exclusively with Ford’s twin-turbocharged 3.5L EcoBoost V6. The truck is certainly not lacking for power, but some of us won’t settle for anything less than the rumble of a V8. Thankfully, a couple of aftermarket companies are happy to swap a V8 into the off-road pickup, including this Hennessey F-150 Raptor that’s packing a supercharged 5.0L Coyote V8.

This video shows that process, albeit sped up quite a bit, from start to finish, and it’s quite mesmerizing to watch. Essentially, it involves pretty much what we’d expect – a complete removal of the stock engine and transmission and all of the associated wiring and ECU, followed by the installation of a fire-breathing V8.

This isn’t a stock Coyote by any means, either. It’s been treated to a vast array of upgrades, starting with the installation of a 2.9L Whipple supercharger that cranks out a reasonable 7 pounds of boost. Hennessey then installs an air-to-water intercooler, high-flow air induction system, bigger fuel injectors, and a new fuel system before tuning the whole thing on the dyno.

The result of those upgrades is an impressive output of 758 horsepower at the crank or 570 at the wheels. That’s good enough to propel this second-gen F-150 Raptor from 0-60 in just 4.1 seconds and down the quarter-mile in 12.2 seconds at 115 miles-per-hour. But perhaps more importantly, it gives the second-gen F-150 Raptor a menacing sound that matches its aggressive looks.

To us, this is exactly how the Ford F-150 Raptor should come from the factory. Thankfully, it looks like Ford will rectify that with the next-gen Raptor, which is slated to receive the automaker’s supercharged 5.2L Predator V8. But for now, Hennessey is already building the blown, V8-powered Raptor of our dreams.

    Wouldn’t the flywheel hp be a more realistic 670.5 rather than 758? After all, the wheel hp is said to be 570, and looking at a loss of 15% to the wheels (570/0.85), that comes out to 670.5 flywheel hp. If we take the flywheel hp as 758, then 570 wheel hp means a loss of 25% to the wheels 570/758 = 0.751. Or am I missing something here?

      It would certainly make more sense but those numbers came directly from Hennessy.

      1. Jason

        15% is typical of rwd passenger cars with lighter wheels and tires. Start spinning 4wd with 22s and all terrain tires and you inevitably get a higher percentage of drivetrain loss

    2. Jeff

      Jason is correct. Unsprung weight is a killer of performance, especially wheel and tire weight. Even moderately heavier wheels and tires have a massive effect on dyno numbers and seat of the pant performance. Shorter gear ratios only help some. 25% loss seems about right to me on a truck like this.

  2. Bishop Stepp

    No offense at all but a lot of people can swap and engine. What I want to see, in detail, is how they modify the harness and pcm to get everything to work. I hope we start seeing swaps for the new supercharged 7.3 into a f150.

  3. Jeff

    Why would Hennessey publish specifics on what they had to do to make this engine work? It’s called Trade Secrets. It’s how they ensure that they get more business, because they’re not there to teach some random person how to do THEIR job. Like when people come into my shop and want me to teach them how to do it, for free. Kick rocks.
