The 2018 Mustang has been quite the success story and Mustang fans everywhere are snapping up the freshened Pony car thanks to its increased horsepower, revised/updated transmission offerings, and such stellar features/options as MagnaRide suspension and Active Valve Exhaust systems. However, as stout as the Mustang is from the factory there’s always room for improvement.

The days of swapping in a cam (one, not four mind you!) are pretty much over for the street enthusiast. The same can be said for cylinder heads and other big-power bolt-on pieces from the pushrod-era. No, these days the quickest way to go fast with Ford’s modular or the newer Coyote four-valve is to supercharge it.

Roush Performance knows that fact cold and has offered various Roush supercharger packages for Mustangs and F-series trucks for going on two decades now. Its latest offering is the Roush Phase 1 Supercharger kit for the 2018 Mustang GT. The development took over a year to bring the kit to market but we’re going to say it was worth the wait! Delivering 700 hp thanks to a larger 2.65-liter front-feed design using Roush Performance’s TVS (Twin Vortices Series) rotors, Roush engineers spent thousands of hours developing and perfecting the new system. It is even backed by a 3 year/36,000 mile warranty when by a Roush authorized dealer or by and ASE-certified technician at your favorite shop.

“Our teams collaborated to create the most rigorously engineered and high performing supercharger system on the market today,” said Jack Roush, Chairman of the Board of Roush Enterprises. “The combination of the 2018 5.0-liter engine and our all-new, fully integrated 2018 Phase 1 Supercharger system yields simply incredible, no-compromise performance.”

In addition to 700 horsepower, the supercharger is capable of 610 lb-ft of torque at 12 psi of boost on just 91-octane fuel, and that output is the same whether you have either the six-speed manual or new 10-speed automatic transmission in the tunnel.

“It took over a year and thousands of hours to bring this new Roush Performance supercharger kit to market, involving feasibility studies, CAD and CAE, design and development,” said Roush. He added that as part of the company’s industry leading testing protocol, the system was “rigorously tested through 17 million cycles at wide-open throttle.”

The kit comes with all installation hardware and exclusive performance calibration. Roush Performance offers an industry leading warranty with its Phase 1 Supercharger system because the individual parts have been designed and tested at the component level for extreme durability, reliability and emissions compliance, just as if it came from Ford on the car from the factory.
