When Ford America announced it was developing a Mustang GT500, there was plenty of rumours about what would power it. Many thought the new 5.0-litre Coyote engine would be used with a supercharger strapped on and horsepower suitably increased. Those rumours were squashed when Ford stated that a new aluminum block version of its supercharged 5.4-liter V8 would be used on the 2011 GT500. But speculation that Ford would still find an application for a forced induction Coyote engine remained.

It now seems that a supercharged 5.0-litre Ford engine will first appear in Aussie next year when it powers the new Falcon XR8 and some FPV vehicles.

The only reason given by American Ford for not fitting the recently revealed Mustang Boss 302 (read news) with a supercharger, which it says would have been the easiest way to obtain greater power from the standard 307kW Coyote V8, was because the original 1969 Mustang Boss 302 engine was not force-fed.

For now the American’s have missed out and the first all-supercharged V8 Ford line-up, could be unveiled at the Bathurst 1000 in October. The range is expected to include a 315kW/550Nm XR8 sedan and ute, FPV GT models powered by a 335kW/600Nm V8 and possibly a special edition model to celebrate the 40th anniversary of Allan Moffat winning Bathurst in a Falcon GTHO.

Following the Bathurst reveal, the Aussie-made force-fed 5.0-litre V8 will replace the current 5.4-litre V8 that powers the outgoing XR8 and FPV’s V8 models.
