They have bolted on their TVS 2650 Supercharger to the 5.0-litre V8 to create a 710bhp Hellcat-killer. All you need to do is bring them your new Mustang GT and watch as they transform it into the 2018 Roush JackHammer Mustang. Apart from the massive blower, they’ll add a new radiator, extreme-duty half shafts, new heat extractors on the bonnet, height-adjustable coil-over suspension, Continental ExtremeContact Sport tyres and standard house-made gloss black wheels. They’ll also give it the company’s customary hockey stripe decals while the cabin will get Roush branding, new embroidered floor mats, and illuminated door sills. The package costs around Dh60,000.
