Prodrive has developed a supercharged 5.0-litre V8 engine for the Australian Ford Falcon, a full sized RWD rival to the Holden Commodore. There will be two states of tune for this ‘Miami’ engine – 422 hp in the Falcon GS and a 449 hp version in the Falcon GT, GT-E and GT-P.

“The old 5.4-litre ‘Boss’ unit used by Ford Performance Vehicles was a tough act to follow but it had reached the limit of its emissions development and mechanical strength,” explains Bryan Mears, MD of Prodrive’s Asia Pacific division. “It took three years and AUD 36 million but the result is a new benchmark for a high-performance V8.”

Following the downsizing trend, the Miami replaces a 5.4L NA V8, saving 47 kg yet providing more power. The supercharger also delivers more torque at lower rpms. The 449 hp/570 Nm (from 2,200-5,500 rpm) unit does 0-100 km/h in under five seconds. 47 kilos is quite a lot saved, and it allows a more neutral front/rear weight bias, according to Ford.

The Miami started life as a ‘Coyote’ V8 block and DOHC cylinder heads from America’s 402 hp Mustang. By optimising the supercharger installation, especially the drive ratio and intake runners, it was possible to reach targets without an intercooler. “This leaves untapped potential for future upgrades using higher boost levels with an intercooler,” Prodrive says.

New parts include uprated exhaust valves, pistons, connecting rods, the complete intake and exhaust system, a high-capacity sump and oil cooling jets to control piston temperature. Parts that were carried over from the Mustang’s 5.0 have been optimised for this application and to gel with the new bits. Unlike a ‘bolt on’ supercharger conversion, long term reliability is ensured here.

All engines are hand-built at FPV in Australia and they’re expecting to churn out 1,500 of these brawny Miamis per year.
