Of the trio of domestic muscle cars for sale now – the Chevrolet Camaro, Dodge Challenger, and Ford Mustang – the Mustang is the only one whose lineup doesn’t include a wildly powerful engine option.
Granted, the GT350’s 526-hp V8 is a pretty special machine with its flat-plane-crank and 8,000-rpm redline, but its output pales in comparison to the Camaro ZL1’s 650 hp and the 840-hp Challenger SRT Demon.
But for Ford loyalists with engine envy, Mustang tuner RTR has a solution in its latest ne plus ultra upgrade package for Ford’s 2018-model-year pony car, which turns the V8-powered GT into a 700-plus-hp speed machine.
RTR is no stranger to modded Mustangs: it currently sells three performance upgrade packages for model year 2015 through 2017 GTs, the most extreme of which is a Spec 3 setup that fits a supercharger to the 5.0-litre Coyote V8 and upgrades its fuel delivery system for 670 hp.
RTR isn’t quite ready to reveal how powerful its 2018 Mustang Spec 3 will be, but will pull the wraps off the new offering tomorrow at the SEMA show in Las Vegas.
But regardless of what the horsepower figure ends up being, one of the most appealing bits about RTR’s creations is that the company warranties its work and lets Ford’s factory warranty take care of any problems not related to the performance enhancements.
Exactly what those are will be revealed at SEMA, but we expect they’ll be similar to the current Spec 3 package, which includes an RTR/Ford supercharger with air-to-water intercooler, upgraded fuel system, lowering springs, and an axle-back exhaust. RTR also fits some body add-ons, graphics, LED grille lighting, and a dash plaque signed by RTR founder and world champion drifter Vaughn Gittin Jr.
We’re guessing the latest Spec 3 package will run more than the $21,000 RTR charges now (which obviously does not include the cost of the car itself).
If more than 700 hp is too much for you, RTR also does more-restrained Spec 1 and Spec 2 mods that can be applied to both GT models and those powered by the 2.3-litre EcoBoost four-cylinder.
