Roush P-51 Mustang revealed

If muscle car fanatics thought the Dodge Demon was only the factory-fresh game in town, the latest Ford Mustang package from Roush will change things.

The Roush P-51 Mustang Tribute takes the Ford Mustang GT's 5.0-litre Coyote V8 and dials it up to extreme levels via an Eaton TVS supercharger.

So the 306kW/530Nm rear-drive Pony car transforms to the Roush P-51 Mustang, belting out more than 540kW and 820Nm of torque. The most powerful Mustang developed by Roush, the P-51 also scores upgraded suspension – three-way adjustable coil-overs – plus exterior and interior enhancements.

Acceleration figures for the wild new Roush P-51 Mustang have not been released but, with the 2.3-litre supercharger forcing more air into the combustion chambers, at full noise it's likely to make your internal organs feel funny... and probably your ears too.

That's because the exhaust note can be altered courtesy of the Roush Active Exhaust System, which features three preloaded profiles: ‘touring’, ‘sport’ and ‘track’. And a custom setting allows owners to tamper with "digitally controlled actuators" within the exhaust system "that can be mapped through an OBD2-based Wi-Fi interface to adjust the exhaust flow," according to Roush.

Roush offers the P51 Mustang with either a six-speed automatic transmission or a six-speed manual (the latter adding upgraded PFC two-piece brake rotors and improved pads).

Different to the one-off Ford Performance Mustang GT350 said to be inspired by the P-51 piston-engined fighter plane from WWII, the Roush creation scores a number of exterior and interior upgrades, starting with the front end and bonnet.

There's a carbon-fibre front splitter with support brackets below the reworked, back-lit grille with new driving lights. A new bonnet with an air scoop, vents and added paintwork adds a little razzle-dazzle to proceedings, while side skirts, side scoops, 19-inch alloy wheels by Weld and a carbon rear deck lid spoiler (plus the expected P51 logos) complete the external visuals.

Inside, the Roush P-51 Mustang gains "custom P-51 Amaretto Tuscany leather seating", a tip of the hat to the warbirds of yesteryear, a P-51 gauge logo, Roush red gear shifter ball and custom pedals.

How much? $US42,500 ($AU56,100), which is almost $US10,000 more than the Ford Mustang GT donor car you'll need in the first place. Roush offers a three-year warranty on its engineering and body work (except carbon-fibre bits).

How many Roush P-51 Mustangs are scheduled for production this year? Only 51 so it’s sure to be a sell-out.

Roush was understood to be working with Ford Australia to offer all sorts of extras for Aussie owners, including a 500kW Roush Stage 3 supercharger kit, similar to the P-51. However, due to what it says were noise issues, the Australian Roush Mustang parts have been axed.

Instead, Aussie Mustang owners can get their hands on a number of suspension and exhaust mods developed in-house by Ford Performance. And the locally-developed Tickford Mustang program also offers upgrades. We've previously tested and enjoyed the Tickford ‘Stang.
