Roush 427R Mustang

Roush 427RBuilding off the already legendary 427 name, one already used for their high performance 427 cubic inch 351w stroker, Jack Roush and crew unveils their most powerful Ford Mustang to date. Based on the Roush Stage 3 Mustang, the 427R adds an additional 12 horsepower for a total of 427 ground pounding ponies (hence the name).

The additional horsepower comes by way of more agressive tuning and a different exhaust system, with much of 427 horsepower power coming from the new ROUSHcharger system which Roush offers via the official Roush website. The supercharger sits atop the standard 4.6L 3v SOHC engine found in the 2007 Mustang.

The 2007 Roush 427R comes standard with many of the trimmings you’d expect from the famed builder, such as a four-piece aerobody kit which includes a stylized front fascia, front chin spoiler, hood scoop and rear wing and ROUSH 18-inch cast chrome wheels with high-performance tires and the special 427R striping kit.

The sports-tuned suspension includes all new front struts, rear shocks, front and rear springs and sway bars and the jounce bumpers. Each component was designed for both comfort and performance by Roush engineers.

Authenticating the vehicle are special Roush fender badges, decklid emblem, a serialized engine bay plate, and a Roush engine build plaque personally engraved by the technician who upgraded the car in the Livonia, Mich., facility. The Roush 427R is available in both coupe and convertible versions, and as with all Roush Mustangs, a 3-year/36,000 mile warranty is included.

“The new ROUSH 427R is a natural extension of our product line,” said Joe Thompson, general manager of ROUSH Performance Products. “It has more horsepower than any car we have produced in our company’s history and I expect that this will become one of the most popular vehicles that ROUSH Performance has ever offered.”
