RATTLA Motorsport is set to unleash a new weapon this coming Demon Energy D1NZ season for driver Shane Allen. The base for the build is unsurprisingly another Ford, but this time they have gone for a 2008 Mustang. 

The Mustang was one of 100 factory-intended, lightweight race chassis sold direct to customers, devoid of everything other than the bare rolling shell — no engine, no interior, no wiring, hell there isn't even a chassis tag.

“We are hoping it will be 200kg lighter than the Falcon, that’s cheap horsepower,” team owner Chris Allen says.

The idea behind going to a Mustang is to have a much more competitive combo. Anyone that's witnessed the RATTLA Falcon in action will know that they have no problem making power. It's just been an uphill battle for three seasons getting the Aussie sedan to steer properly — a key component for drifting. The Mustang platform has been developed in America over the past 12 years, thanks to the likes of Vaughn Gitten Jr and Justin Pawlack (JTP), and as such every component you can dream of is available off the shelf for the application.

The Mustang will run a steering-lock kit as seen in the likes of the JTP Mustang, offering 68 degrees of lock. Suspension is JTP’s own specifically developed items, while down the back it’s likely to run a three-link ED nine-inch, as the popular Winters Quick Change IRS will struggle with the torque output. 

So exactly what will the Mustang be powered by you ask? Well, the Peterson dry-sump tank ...

and the rather large oil breather mounted in the rear should point to something rather serious being fitted under the hood. 

But popping the hood certainly gave away no clues, as the engine is yet to be screwed together. 

When it comes to the engine, the Mustang will run a 468ci Ford V8 with modified Nascar heads similar to the RATTLA Falcon, although around 75kW more is expected as they can now run a bigger base circle on the cam. This allows for larger lobes and lighter valve springs. As Chris explained, it will be a “stump puller.”

Of course fielding this much power, and torque figures north of 950Nm, makes keeping a clutch and gearbox together no easy task. After trying a few different sequential and dog-engagement H-pattern boxes over the years, the team will run a new six-speed sequential out of Europe. 

The chassis came with an extensive roll cage already fitted. It features plenty of extra gusseting and triangulation for strength. 

To aid in that chassis rigidity, the shell has been stitch welded to a very high standard. Everywhere we looked the welds were exactly the same length and space apart. Talk about attention to detail. 

While the team awaits a big shipment of parts out of the USA, there was still plenty of parts stacking up in the shop — components like the Woodward steering column. Interestingly the Mustang has been converted to be right-hand drive.

“We made the car right hand drive so that if Shane was to jump back into something else like the Falcon he wouldn't have to adjust back.” Chris explained. 

The braking package is one of the more interesting combinations, with a Tilton 600-series floor-mounted pedal box mated to very large two-piece rotors, front and rear, and six-piston Endless callipers, front and rear. What makes this interesting are the rear Endless Drift 6R callipers, which are dual fed with four pistons for the foot brake and two for the handbrake, both with separate pads. This removes the need for a bulky dual calliper set-up, saving unsprung weight. 

We will check back in with the team once the big box of goodies arrives from the USA and the team make some progress. So keep on checking back here at The Motorhood.
