The PTWA process uses air and electricity to create a plasma jet of 35,000 degrees Fahrenheit, which melts a steel wire that is fed into a rotating spray gun. Using atomized air, the melted steel wire is blown into a specially machined surface of the aluminum-block engine cylinder bore. In the process of melting and applying the metal to the surface, the steel wire oxidizes, creating a composite coating consisting of both iron and iron oxide.
“Ford’s Global Research and Advanced Engineering looks to all industries for advanced technologies – and this comes from aerospace. It’s the same technology you would find on aircraft engines,” said Glenn Jorgensen, SVT powertrain team leader. “We’ve invented a coating as a replacement for cast iron that delivers improvements in power and performance and fuel economy.”
The new engine also has its roots in the iconic Ford GT. The new 5.4-liter engine is an evolution of the GT engine, with improved block structure through the use of a unique bulkhead chilled process and six-bolt billet main bearing caps. This new advanced engine will exceed Ford GT performance with its traditional supercharger technology.
“The Ford GT has solidified itself as one of the world’s most coveted supercars. To make improvements to the engine from this supercar and make it available in a Mustang is impressive,” said Kerry Baldori, SVT global performance vehicle chief functional engineer. “The aluminum-block engine is robust and strong enough to produce the performance numbers and durability our customers demand.”
Increased power and increased fuel economy
The 2011 Shelby GT500 combines power and fuel economy into one impressive package. This 2011 Shelby GT500 will be the first modern Shelby without the gas guzzler tax, thanks to the EPA-projected 23 mpg highway and 15 mpg city it will deliver. This is up from 22 mpg highway and 14 mpg city for the 2010 model.
The 5.4-liter V-8 achieves 80 percent of its torque between 1,750 and 6,250 rpm, giving the car a higher level of performance feel. A larger two-row intercooler for the supercharger system has 40 percent more cooling capacity, helping to make power more consistent in higher ambient conditions.
Fuel economy gains come from the new 102-pound-lighter aluminum-block engine, EPAS and detailed aerodynamic changes to the underside of the vehicle.
