New 2010 Ford SVT Raptor Engine Endures Extreme Testing to Meet Off-Road Enthusiast
The 2010 Ford F-150 SVT Raptor launches with the proven three-valve Triton 5.4-liter V-8 engine delivering 320 horsepower and 390 ft.-lb. of torque; a new 6.2-liter engine with an estimated 400 horsepower and 400 ft.-lb. of torque becomes available shortly after launch
Both engines underwent extreme laboratory testing, including running the engines at over 6,000 rpm for more than 150 hours
The engines also were put to the test in the desert on a 62-mile evaluation loop to prove out the durability demanded by high-performance, off-road enthusiasts

BORREGO SPRINGS, Calif., Aug. 17, 2009 Ė Mike Harrison's enthusiasm for V-8 engines is apparent. Harrison, Ford Motor Company's premium V-8 systems manager, is particularly excited about the availability of the new 6.2-liter V-8 that will power the Ford F-150 SVT Raptor.
Producing an estimated 400 horsepower and 400 ft.-lb. of torque, Harrison rattles off the new engineís components and features quickly and easily, pointing them out and explaining them with more than a trace of pride.
Harrison wants that engine to perform to its maximum capabilities so that customers of the F-150 SVT Raptor won't have anything to worry about. In short, if the engine can withstand the rigorous testing Ford demands during the development cycle, it can withstand almost anything the most enthusiastic off-roader can dish out, even desert racers.
The testing is intense. It's cruel, dusty and dirty. By working in the lab to push the engine to its limits, the process simulates how a customer would use the engine. But then it goes a little bit further.
"Running it over 6,000 rpm for more than 150 hours, which is over the peak power limit of the engine, really puts it through its paces," Harrison said. "We've tested it in harsher operating conditions on the engine dyno than would ever be seen by a customer who races."
Beginning in fall 2006, Harrison and his team tested more than 50 engines, with each running through a dozen separate tests. Evaluations included high-speed durability, crank-torsional testing, aeration and a thermal cycle where the engine is "shocked" from one temperature extreme to another.
As with all Ford programs, attention to detail was a hallmark of the testing process.
"We did a careful teardown of each engine at completion of testing to ensure there absolutely are no issues with the hardware," Harrison said. "These are very demanding, very stringent tests Ė far more stringent than anything you would see on a truck Ė racing or otherwise."
