Those lucky stiffs over at Autoblog have just spent some time with the new Roush 427R Mustang, and it was no cruise around the blog. Nope, these guys got the time to spin it on a dyno and even take a bunch of passes down the strip. The 427 stands for 427 hp, and the translated to 356 at the wheels, with 330 ft/lbs. Those numbers were solid enough for a 13.2 pass down the 1/4 at 108.77 mph. While that number may disappoint some, don’t forget that most of the big magazine tests are done by pro drivers.

Roush press release about the 427R after the break.

LIVONIA, Mich. (Sept. 5, 2006) – Yet again raising the standards in the Mustang world, ROUSH Performance unveiled the new 427R model with a total of 427 horsepower under the hood and ready to unleash with the turn of a key. This is the most horsepower ever offered on any version of the ROUSH Mustang.

The number 427 has been intertwined in the Ford product line for many years, both as a car model and one of the most powerful and legendary engines in their line. It is only natural that ROUSH, as perhaps the best Ford engine builder in the country, is the company to reintroduce the number to the automotive lexicon using modern engine technology.

Based on the acclaimed ROUSH Stage 3 Mustang, this version is slightly less in content but includes 100 percent of the fun factor. The 427R horsepower package is highlighted by the intercooled ROUSHcharger* system which adds 115 horsepower and 65 lb-ft of torque to the base Ford 4.6L, 3-valve V8 powertrain system. The additional power upgrade comes via a ROUSH-engineered ECM calibration which has been specially-tuned to work in harmony with the different exhaust system used on the vehicle.

Further adding to the style and performance of the 2007 ROUSH 427R is 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 the industry-leading ROUSH automotive 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 a complete listing of the content can be found online at www.RoushPerformance.com.

To assist customers in creating their own personalized one-of-a-kind vehicle, a variety of options are also available which include white face gauges, interior carbon fiber design dash trim kit, short throw shifter, door sill plates, and ROUSH sport leather seating.

“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.”

    I have a very well built carbureted 462 in my 67 GTO with E heads putting out 535 rwhp on pump gas, and an equally impressive torque curve. I just utterly destroyed one these about 20 minutes ago in a street race. They are lovely new beasts but I beat the thing like a rented mule and had her by about 10 cars before we hit the 1/8th mile. By the time I had hit 100, even though she had provoked this little exchange of blue oval vs old school pontiac she wisely quit and laid off the throttle. It was downright embarrassing for her. To be fair, the poor driver who picked this fight had no ideas she was going up against a VERY experienced driver with a large number of low 11 second time slips in my 67 GTO prior to adding a new tubular suspension up front with Hotchkis Extreme sway bars front and rear, and full Metco Billet Aluminum Control Arms out back with airbags, Eibach springs all around and KYB GasAdjust Shocks. The sways are huge at 1 5/8 front, and 1 3/8 rear. I have about 60 grand invested, so it was a fair contest in terms of dollar bang for the buck, I can pull almost a full G consistently in the old brick so it aint gonna catch me in the corners either. This car is scienced out perfectly. The new Roush owner pulled up next to me, revved her supercharged 427 a few times, I replied by opening up my 3.5 inch exhaust dumps and revved the 462 roller motor to 7000 rpm a few times to let her know this was no pushover. It was fun for her too, she pulled up even after the utter destruction of her car, and went on and on about how fast and beautiful my car is. She was never even IN the race if you get my drift, I let her launch and then hit it, and hooked. I was long gone baby! She was in love with my car. I agreed with her and my day was made! No lives other than our own were risked during the making of this experience. I am sure I could have had her lunch in my factory stock 2006 6 Speed GTO just as easily. That turns consistent 12.9′s at 107 mph in my hands. The 462 GTO does 118 MPH with a few 121 and 122′s That means I am not getting nearly as much out her on the track as I could, but will likely not change anything at this point. Drive carefully and wisely.
