The image above shows the 5.0L V8 engine that will power the 2015 Ford Mustang GT topped by what appears to be an Eaton TVS R2300 supercharger. The Ford Racing Facebook explained that this shot provides “a sneak peek at the Ford Racing super charger development for the 2015 Ford Mustang GT 5.0” No other information was included, but the person posting as the Ford Racing Facebook page reminded us all that the Ford Racing offers a supercharger package for the 2011-2014 Mustang GT that increases the output up to a whopping 624 horsepower and 536lb-ft of torque.The 2015 Mustang GT is expected to pack slightly more power than the 2014 Mustang GT so I would guess that the supercharger package for the 2015 GT would have slightly more power as well. The most significant part of this 2015 Ford Mustang GT supercharger testing image is the supercharger itself. The 2011-2014 Mustang GT supercharger package that increases the output from 420hp to 624hp uses a 2.3L Whipple twin screw supercharger unit.
The Ford Racing page released a photo of the supercharger going into the 2015 Mustang GT 5.0. No specs were released, but they did remind us that the current 5.0 FRPP provides 624 hp and 536 lb-ft. of torque
