Hennessey’s Chevy Silverado Goliath 800 Puts Down 629 RWHP On Dyno

Hennessey and power go hand in hand in Texas, where the tuner has no qualms about building powerful performance vehicles. The company offers an assortment of power upgrades for a variety of makes and models ranging from Ford to Ferrari. Their latest creation is not one of them, however. Instead, it’s a powerful Chevrolet Silverado called the Goliath 800.

If you know Hennessey, you know that 800 is the production of the truck. The tuner uploaded the YouTube video of the truck to the test stand where it put 629 horsepower (469 kilowatts) on the rear wheels. Calculating the rear of the tuner towel – representing a 25% transmission loss – puts the flywheel power at 838 hp (624 kW) for the 6.2-liter V8. This represents a gain of 245 hp (182 kW) compared to the factory’s production in stock.

Hennessey says the Goliath 800 is available for the 2019 and 2020 Silverado and GMC pickups equipped with the 6.2-liter V8. Information on the Goliath 800 is not yet available on the company website, but the Goliath 700 shows what a customer can expect: a high-flow intercooler and air intake systems, a custom camshaft, an HPE engine management calibration, and much more.

We can spot the Goliath front bumper, which has five LED lights and a brush guard on the Goliath 800. The truck wears 10-spoke, 20-inch Hennessey wheels, and the raucous noise of the exhaust makes also alluding to all the improvements made.
