A photograph of an aluminum supercharger housing with the iconic Shelby Cobra logo and the characters “5.2 L” cast into it has been leaked on the Mustang6G forums, and we’re scratching our heads trying to imagine what it could possibly be beside the blower that will help propel the rumored S550-based Shelby GT500 Mustang. More supporting evidence is offered in the form of an official-looking oil chart for the 2020 model year, which lists each and every Ford production engine for 2020, with what oil to run in it.
At the very bottom of the chart: “5.2L Supercharged Mustang GT500”.
So, it seems that a Ford Shelby GT500 Mustang is on the way for 2020 at the latest, and it will draw on a supercharged, 5.2-liter V8 for power. While it’s easy to assume that the engine will be a blown version of the GT350‘s flat-plane-crank “Voodoo” engine, given the identical displacement, it might make more sense for Ford to use a cross-plane crankshaft in the new Shelby GT500. The automaker’s performance parts division already sells the cross-plane-crank “Aluminator 5.2 XS” crate engine, which produces 580 naturally-aspirated horsepower from 5.2 liters of displacement.
