Roush's New Mustang Makes Most Lamborghinis Look Slow

Engine / 55 Comments

How do you improve an icon?

Even though the Mustang GT's 5.0-liter V8 is one of the most advanced V8 engines on the market, there's still one surefire way to improve it by all metrics–well, maybe not fuel consumption. By adding a supercharger. If you agree, the folks over at Roush Performance will be happy to help. The company's Phase 1 Supercharger Kit bumps the Mustang's power figures from the cute 460 horsepower it leaves the factory with to a monstrous 700 horsepower, now paired with 610 lb-ft of twist.

To put the Roush Mustang's performance metrics in perspective, it makes the Lamborghini Huracan Performante's 631-horsepower and 443 lb-ft of torque seem inadequate—and for a fraction of the price. Roush's Phase 1 Supercharger Kit costs just $7,699.99 on top of the cost of a new Mustang GT. The Phase 1 pack adds Roush's R2650 TVS supercharger, which, on 91 octane, can cram an extra 12 psi of compressed air down into the cylinders for maximum boom. To cope with the extra stress, the kit also adds an all-aluminum intercooler, a new radiator, a high-flow induction system, plus new engine calibration to harmonize it all.

Because of Roush's long-standing affiliation with Ford Performance, the system comes with a 3-year/36,000-mile Limited Powertrain Warranty, which is a nice bit of piece of mind when you decide to start modifying a brand new Mustang. The Phase 1 package is effectively an entry-level version of Roush's new $14,765 JackHammer package, which adds 10 more horsepower, plus driveline and visual modifications. Roush actually claims its new package is the highest rated Phase 1 Supercharger it's ever made, and at $43,000 (after you factor in the price of a Mustang and the kit), the Roush-tuned Mustang is easily the cheapest way to get your hands on 700-horsepower.
