The Hennessey Velociraptor is one mean truck.
Texas-based tuners Hennessey Performance has finished development on the Hennessey VelociRaptor 600 Twin Turbo and VelociRaptor 800 Twin Turbo trucks, based on the recently-released Ford F-150 SVT Raptor. Both special vehicles use a 6.2-liter V8 engine, just like the base model, but with a host of upgrades.
Getting the VelociRaptor 600 to produce 605 horsepower (451 kilowatts) and up to 622 pound-feet (842 newton-meters) of torque was no easy feat. The company installed twin ball bearing turbochargers, dual intercoolers, improved fuel injection system, and a new stainless steel exhaust. Aside from modifying the engine's control unit, the firm adds an electronic boost controller, dual blow-off valves and dual 44 millimeter wastegates.
It takes a bit more to make the truck a VelociRaptor 800. After adding aluminum pistons, steel connecting rods, a balanced crankshaft, and further modifications to the ECU, the engine kicks out 810 horsepower (604 kilowatts). Maximum torque rises to an impressive 745 pound-feet (1,009 newton-meters).
Look for the Hennessey VelociRaptor 800 to sprint to 60 mph in about five seconds flat, with the 600 being a few tenths of a second slower. Pricing for the upgrade package starts at $22,950, with installation costing an additional $7,000. Base price of the 2010 Ford F-150 SVT Raptor begins at about $42,000.
