The Ford Mustang “Espionage” is not your regular muscle car. In fact, it borders on overkill, even for cars which are synonymous with overkill. Why? Because it has 959 horsepower; that’s more than twice as powerful as the most powerful Mustang you know.
The Espionage is the latest creation from the Ringbrothers. If you don’t know them, Mike and Jim Rung are brothers who run a repair and collision shop in Spring Green, Wisconsin. They are also acclaimed car modders who build one to two custom cars every year. They have won plenty of awards because their builds have been, quite simply, breathtaking. Just look at their earlier builds, from the 2013 Mustang Switchback to the gorgeous 1964 Fairlane Afterburner.
So, the car’s 959HP and 858 pound-feet of torque are produced by a 427 cubic-inch LS7 V8 engine, complete with supercharger clocks. Among the recent factory Mustang models, the most powerful one produces a “mere” 435HP.
But that’s just the beginning of what makes this Mustang unique. The car is founded on the frame of the 1965 Mustang Fastback, and that’s as far as similarities go. The brothers widened the frame by two inches on either side, and used carbon fiber to cover the entire body.
The brothers then finished the exterior in a custom color called “Spy Green”, based on the BASF Glasruit 90-Line Waterborne paint color. To keep up with the insane torque from the engine, the brothers also custom-made the car’s drivetrain.
They paired the Goliath engine with a 6-speed Tremec transmission. The brakes are 6S calipers and Baer 14.0-inch discs. The exhaust is a Flowmaster Supper 44.
Calling this car a beast is an understatement. But it just goes to show that, when it comes to raw performance, car modders can make cars that the original manufacturers might never match.
