It's been well documented by our very own Ed Loh that the 2010 Ford F-150 SVT Raptor is a bona fide beast. But with "only" 310 horsepower onboard courtesy of a widely used 5.4-liter V-8, a little more oomph would be more than welcomed. So for those considering waiting for the more powerful 6.2-liter V-8 coming from SVT this winter (thought to put out 400-horsepower/400 pound-feet of torque), Hennessey Performance Engineering may have just the right alternative.
Turning this beast into a VelociRaptor 500 is a HPE supercharger running at 8 psi. Mix in a new fuel system, headers, exhaust, air filter, and ECU, and a grand total of 501 horsepower and 520 pound-feet of torque are at your disposal -- that's over 100 horses and pound-feet more than our best guess at the new 6.2's output.
In a straight line, the VelociRaptor 500 hits 60 mph almost three seconds faster that the stock 5.4-liter-equipped model (5.6 seconds versus 8.0 seconds). The coveted 1320-foot stretch of pavement is devoured in 14.1 seconds at 97 mph.
Exterior-wise, HPE hasn't changed a thing, save for a few emblems denoting its uniqueness. Only 100 units will be made this year, so if you're interested, you'd better act quickly. But be prepared to set aside a healthy chunk of change. The kit alone without installation and tuning runs for $10,950. Add in tuning and installation by an authorized agent and it'll cost you around $14,950.
For all you bean counters, the stock Raptor starts at $38,020. Tack on the full HPE kit and you're looking at around $53,000, or about $11,000 more than the upcoming 6.2-liter variant ($41,995).
