Roush Performance yesterday live-streamed a dynamometer session on Facebook in which they ran the mighty, aggressive Roush 729 Mustang. It appears to be the very same Grabber Green Roush 729 that the company unveiled at the Specialty Equipment Market Association Show last year – a snarling, supercharged beast designed to recall the legendary Boss 429.
Roush isn’t ready to reveal numbers just yet, saying in yesterday’s live stream: “Can’t say today, can’t say this week, but they are very impressive and you will see them very soon.” Last year’s Roush Stage 3 Mustang put out 670 horsepower with a blown Coyote V8, and that was before dual-injection was introduced; the addition of direct-injection in the new-and-improved Coyote ought to have raised its limits even higher.
The Roush 729 Mustang makes use of a Roush Performance supercharger with a cold-air intake and a Roush Air Gobbler ram-air system. A 3-way-adjustable Roush coilover suspension, gold painted Brembo GT-Series brakes, and Vossen/Roush custom RVS wheels enhance braking and handling, but for us, the real party piece is the custom Grabber Green body. It features a functional Roush/Stratasys hood scoop in black, a Roush/Stratasys custom wide-body kit, and a collection of Roush/Anderson Composites carbon-fiber aero pieces: front splitter, mirror caps, side rockers, rear aerofoils, and rear spoiler.
We look forward to finding out how much power the Roush 729 Mustang makes – and whether or not it will ever be sold through Roush’s dealer network. Stay tuned for more.
