Bought brand new from Jarvis Ford in 2022, this Mustang GT never even had the chance to settle into showroom life. It was hauled straight to East Side Mustang Enhancement, where it received a Roush Stage 3 Supercharger package—fully engineered, built and complianced right here in South Australia.

But that was just the opening act.

Over 700 painstaking man hours have been poured into creating what can only be described as an all-out street weapon. Every nut, bolt and calibration has been obsessed over. Gear ratios were tested and refined. Only the finest performance components made the cut. No shortcuts. No compromises. Just an uncompromising pursuit of speed, reliability and outright performance.

The result is far more than a modified Mustang—it’s a purpose-built powerhouse that’s as brutally fast as it is meticulously engineered, representing the absolute pinnacle of what a modern S550 Mustang can become.

The spec sheet on this Mustang is nothing short of staggering.

Beneath the skin you’ll find billet oil pump gears, an X-Force header package feeding into a 3-inch MagnaFlow Competition exhaust, a Harrop oil cooler, a custom second Shelby transmission cooler and upgraded feed lines, an F1 Interchiller, a KPM 1,500hp fuel system and controller, three dedicated ECU calibrations, G-Force 2,000hp half shafts, a GJD tail shaft, an Eaton Truetrac LSD with 3.31 gears, and a set of Weld Racing bead locked wheels ready to put every horsepower to the pavement. Not to mention the Custom Roush Interior imported and hand made in America!

And that’s only scratching the surface.

Every component was chosen with one goal in mind—to create a Mustang that is brutally fast, relentlessly reliable, and surprisingly refined. It’s the kind of car that can annihilate the throttle one moment and cruise home in complete comfort the next.

This isn’t just a collection of high-end parts. It’s a meticulously engineered package, built by the team at East Side Mustang Enhancement with an obsessive attention to detail. The result is a Mustang that doesn’t just make big power—it delivers it with confidence, consistency and a level of drivability that’s rarely seen in a build of this calibre.

A car of this calibre deserved more than an ordinary handover, so it was only fitting that the keys changed hands at East Side Mustang Enhancement—the very place where GTWPN’s journey began. Joined by Andy from East Side Mustang Enhancement and Jonathan from Aus Speed Automotive, it was a memorable occasion and the perfect way to celebrate the passing of the torch.

We’re still in touch with the new owner today and look forward to seeing GTWPN continue to turn heads on the street, at car shows, and wherever its next adventure takes it.

Built with roll racing in mind, GTWPN was engineered to deliver relentless performance without sacrificing reliability. Every aspect of the car was carefully dialled in by the team at East Side Mustang Enhancement, ensuring it performed at its absolute best every time it hit the road or track. To maintain that standard, the car was meticulously serviced before and after every race event, giving it the longevity and dependability that matched its incredible performance.

Unfortunately, due to unforeseen circumstances, the owner made the difficult decision to part ways with GTWPN and entrusted Aus Speed Automotive with finding the right buyer. Knowing how special this Mustang was, we took the time to showcase its story properly, ensuring it was presented with the respect and attention it truly deserved.

Shortly after posting it for sale, we received a call from an enthusiast who had been captivated by the car from the moment he saw it online. An inspection was arranged, and from the instant he laid eyes on GTWPN in person, it was clear this wasn’t going to be just another viewing. The final confirmation came with the press of the start button—as the supercharged V8 came to life, it was love at first sight.

After some friendly negotiations, an agreement was reached that left everyone smiling. The seller was confident the car was going to an owner who truly appreciated it, while the new owner couldn’t wait to begin the next chapter with one of the country’s most impressive modern Mustangs.
