How do they get to the 1,000 horsepower figure you might ask, well Hennessey starts with the 7.0-liter LSX V-8 and than adds a pair of turbochargers and air-to-air intercoolers, forged pistons, rods and crank. A set of high-flow heads, custom cam, reworked intake manifold, larger fuel system and 3-inch stainless steel exhaust round out the major additions. Handling the 900 pound-feet of torque will be no small task so Hennessey adds a beefed up six-speed transmission with twin-disc clutch, an optional heavy-duty six-speed automatic is also available.
