With the Shelby GT500 still to come, the most powerful version of the Mustang that Ford currently offers is the GT350 with its 526 horsepower (392 kW) and 429 lb-ft (582 Nm) of torque. That’s a lot of muscle, but it’s still a far cry from the 797 hp (594 kW) and 707 lb-ft (958 Nm) offered by the Dodge Challenger in SRT Hellcat Redeye spec. So what’s a Blue Oval pony-car fan to do?
Turn to the aftermarket, that’s what. And there’s fortunately no shortage of tuners eager to massage the Mustang. Like Roush, for example, which has just announced a 700-plus-horsepower upgrade of its own.
The 2019 Roush Stage 3 Mustang bolts an Eaton R2650 supercharger (with a custom inlet) to its 5.0-liter V8 to produce a massive 710 hp (529 kW) and 610 lb-ft (827 Nm) of torque – just like the JackHammer released last year. That’s an extra 250 hp (186 kW) over the 460 hp (343 kW) with which the Mustang GT comes stock – or as Autoblog puts it, about a Focus ST’s worth of added output.
Fortunately Roush has packed other enhancements into its latest Stage 3 kit to help keep all that power under control. There’s a new set of coilovers (available with three-way adjustability), a new set of 20-inch alloys, an optional adaptive exhaust system, a fresh aero kit, and a smattering of interior enhancements.
Enticed? Roush is taking pre-orders now for the package that starts at $22,925 and comes backed by a three-year/36,000-mile bumper-to-bumper warranty, with five years and 60,000 miles of coverage for powertrain components. Of course, you’ll need a Mustang GT to serve as the basis, which itself starts at $35,190. So assuming you start with a brand-new donor car, you’ll be looking at upwards of $58,115 – just north of the $57,240 sticker on the Shelby GT350, a little less than Dodge charges for a similarly potent (717-hp) Dodge Challenger SRT Hellcat, and well short of the $71,045 you’ll have to dish out for the the more potent Redeye.
Unfortunately there’s only the one image of the modified Mustang released at this time, so here’s a quick video of some Roush-upgraded Fords doing donuts to tickle your senses in the meantime.
