Check out Hennessey Performance’s HPE650 upgrade for the Ford F-150 as it undergoes testing on the dyno.

Before you can create a work of art, you must first start with a blank canvas. In the case of Hennessey Performance, that blank canvas is a Ford F-150 XLT equipped with a 5.0-L V8. That’s a lot of stuff to call a blank canvas, but the artists over at Hennessey need no more than this.

To start, they install a 2.9-L supercharger, giving the big V8 it’s first taste of forced induction. From there a new air-to-water intercooler is installed along with new fuel injectors to handle the engines new fuel demands. Next comes a few tweaks to the engine’s ECU, some dyno testing and calibration, and when everything is said and done, you have Hennessey’s HPE650 upgrade for the F-150.

When the F-150 started life with its stock 5.0-L V8, it produced 395 hp and 400 lb-ft of torque at the crank. According to Hennessey’s dyno test, that power dropped to 339 hp and 359 lb-ft by the time it reached the rear wheels. That’s about 15% lost to Ford’s 10-speed automatic transmission.

After the HPE650 upgrade is installed, power jumps to 650 hp at the crank, with the dyno test revealing a rear wheel horsepower of 547 with rear wheel torque at 455. That’s actually 14% power loss, which means that Hennessey’s upgrade actually made the pickup more efficient.

This may be the first time in Hennessey’s history that an HPE upgrade made the vehicle better able to use all that ludicrous power it had been given.

Along with the oodles of power, Hennessey will naturally provide some serialized plaques, some exterior badging, and a 3-year / 36,000 mile warranty. Optional upgrades include a set of Brembo brakes, new 22” or 20” tires, Toyo off-road tires, sway bars, lowering or raising kits, and new Hennessey front and rear bumpers complete with 5 LED light bar.

But the whine of that supercharger is really the only upgrade you need.
