One of the most powerful trucks is the Hennessey Velociraptor.
Hennessey Performance, a Texas-based tuner, has completed development of the Hennessey VelociRaptor 600 Twin Turbo or VelociRaptor 800 Twin Turbo trucks. These trucks are based on the Ford F-150SVT Raptor. These special vehicles share the same 6.2-liter V8 engine as the base model but have a number of upgrades.
It was not easy to get the VelociRaptor 600 600 to produce 605 horsepower (451 Kilowatts) or up to 622 pound feet (842 newton meters) of torque. The company installed dual turbochargers with ball bearings, dual intercoolers and an improved fuel injection system. It also added a stainless steel exhaust. The company also modified the engine’s control system by installing an electronic boost controller and dual blow-off valves.
To make the truck VelociRaptor 800, it takes some more. The engine produces 810 horsepower (604 megawatts) after adding aluminum pistons and steel connecting rods to it. Maximum torque is 745 lb-ft (1,009 newton meters).
The Hennessey VeloCiRaptor 800 can sprint to 60 mph in five seconds flat. The 600 is a fraction slower. The upgrade package costs $22,950 and installation is an additional $7,000. The base price for the 2010 Ford F-150 SVT Raptor is $42,000.
