Rumors are flying....
Pulled that quote off of another board. I have also heard there is no room for twins, and the vid showing the new mustangs at the ring sound like a blower scream!
UPDATE (June 30, 2011): FIN now knows the liter of the new 2013 Shelby GT500. Our source within Ford has now made mention that the SVT engine was developed from the Mustang GT's 5.0L V8! With 650 horsepower, the average for a liter will be an astonishing 130 each!
To “one up” General Motors’ releasing of the 556 horsepower Chevrolet Camaro ZL1, Ford’s SVT will give the 2013 Shelby GT500 a heart transplant. Unlike the current supercharged 5.4-liter, the new engine will be turbocharged. Though FIN cannot bring you the engine's new displacement, a 5.0 and 5.8 have been rumored. We can tell you that the engine will deliver a Camaro-killing 650 horsepower according to our sources. This upgrade will make the 2013 GT500 the most powerful, factory made Mustang ever.
