We probably won’t know ’til SEMA. American automotive tuner Roush Performance has just revealed a super powerful Ford Mustang that is set to make its debut at SEMA 2015.

How Did Roush Make This Mustang Crank Out 850 HP?

The special Mustang has been fully kitted out with Roush’s “TrakPak” that enables it to produce a monstrous 850 hp from its 5.0 liter V8 engine.

Although Roush is thus far tight-lipped on how this was achieved, we speculate that the installation of a larger aftermarket supercharger as well as a 75mm supercharger pulley and upgraded fuel injectors had something to do with it.

In addition to the performance upgrades, Roush treated the Mustang to some aggressive aerodynamic modifications such as a ridiculously a large rear wing, rear diffuser, side skirts and a mean- looking front splitter. Full details of the upgrades are expected this week when SEMA 2015 opens its doors.
