GeigerCars builds Mustang GT520

UPDATE: high resolution image gallery added after jump

click on image to enlarge is beginning to put some tuners in the U.S. to shame with its highly modified versions of American muscle. While working on its supercharger kit for the Mustang GT, it decided to go one (or 20) steps further and build a complete show car to show off their work. The stock 4.6-liter V8 of the Mustang GT has been enlarged to 5.2 liters, and with the aid of a belt-driven supercharger and an ample intercooler now develops 520 horsepower and 415 ft-lbs. of torque. The 520GT routes all those new ponies to the rear tires through a modified six-speed manual and can snap off a run to 62 mph in 4.2 seconds on its way to a 178 mph top speed. The suspension and brakes were also upgraded and a set of 20-inch GeigerCars chrome wheels was also added (gotta have the bling).

Since it is a show car, the 520GT has to look the part and achieves this with a specially developed aero-enhancing body kit that can fit on both coupes and convertibles. A deeper chin spoiler scoops up air and shovels it into the big oval air dam that feeds the intercooler, while an integrated diffuser in the rear fascia and large rear wing keep things steady at speed. The 520GT would also feel right at home in an IASCA event thanks to a 10,000-watt JBL sound system.

GeigerCars will be taking the 520GT on tour around the globe next year, so hopefully it will show up in the U.S. and teach our American Mustang tuners that there's no monopoly on pony power.

The Power Of Orange: Mustang GT 520

How much excitement and sporty character can the current Ford Mustang really offer? The answer to this question delivers 520 hp / 382.7 kW, reaches a top speed of 287 km/h, and in addition to racing-inspired body styling painted a hot orange offers an exclusive interior with 10,000-watt sound system. The show car Mustang GT 520 from (Truderinger Str. 265, D-81825 Munich, phone: +49 / (0) 89 / 42 71 64 13, fax: +49 / (0) 89 / 42 71 64 10, e-mail:, website:, Europe's leading tuner of American automobiles, demonstrates the true potential of the reborn sports car legend.

More power through more displacement and supercharge the whole thing to boot is the recipe behind's performance tuning of the Mustang GT V8 engine. Displacement was increased from 4.6 to 5.2 liters, and the engine was extensively reworked. Precision-machining of both cylinder heads, installing sport camshafts and reinforcing the valvetrain are part of the power treatment as is a belt-driven supercharger with generously dimensioned intercooler. A fully stainless-steel high-performance sport exhaust system with high-performance manifold and metal catalysts round out the engine conversion.
In this guise the eight-cylinder engine produces a proud maximum power output of 520 hp / 382.7 kW, up from stock 300 hp / 220 kW. The peak torque of 563 Nm is available at 4,730 rpm. Power is transferred to the rear wheels via a modified six-speed manual gearbox and a sport clutch. The Mustang GT 520 delivers exceptional performance: The sprint from 0 - 100 km/h takes just 4.2 seconds; top speed is 287 km/h. For an optimal supply of cooling and intake air the Munich tuner has also developed a special hood with large air dams.

The GT 520 engine was created during the development of the supercharger kit for the Ford Mustang GT, which will be available this fall. It boosts power output of the normal V8 engine to 412 hp / 303 kW. Already on sale is the stainless-steel sport exhaust that is also used on the show car. This exhaust system not only delivers a more exciting exhaust note but also more spectacular looks with its two large chromed tailpipes.

Another innovation is the sporty aerodynamic-enhancement kit that is designed to fit both body styles of the current Mustang, convertible and coupe.
The new front fascia was designed to be easily exchanged for the production bumper, thanks to its precise fit and the retention of the original mounting points. The large oval air dam ensures ample supply of cooling air for all radiators and coolers. The lateral openings were shaped to optimize the air flow for best possible brake cooling. The integrated front spoiler reduces lift on the front axle.
The rear fascia with integrated diffuser is also designed as a replacement part. Together with a large adjustable wing it produces notably more downforce on the rear axle than the production car.
The rocker panels round out the sport package for the latest Mustang models.

The spectacular appearance is further enhanced by multi-piece chrome wheels. The Mustang wheel houses offer enough space to fit five-spoke wheels in size 9Jx20 in front with size 255/35 ZR 20 tires. The rear axle features size 10Jx20 wheels with tires in size 285/30 ZR 20.

Specially matched to this extreme tire/wheel combination is the height-adjustable coil-over suspension. Firmer damper settings and a ride-height lowering of up to 50 millimeters lend the two-door even more agile handling. sport sway bars minimize body roll in fast corners and make turn-in more precise.
To keep the exceptional performance of the GT 520 safely in check at all times has developed a high-performance brake system for the Mustang. It features vented and cross-drilled 355 x 32-mm brake discs and four-piston aluminum calipers on the front axle. For even better stopping power the sport brake system with 355 x 32-mm discs and four-piston aluminum fixed calipers can be installed additionally on the rear axle.

The interior of the show car is hardly recognizable as belonging to a Ford Mustang: The exclusive fully leather black interior features highly contoured sport seats for improved lateral support, and, most of all, a multimedia sound system from JBL that was custom-tailored acoustically and visually to the interior of the Ford Mustang coupe.
The sound system is controlled by an Alpine IVA-W200Ri head unit connected to a digital PXA-H701 sound processor from the same manufacturer. It allows the driver of the GT 520 to shape the sound according to his or her personal preferences. Thanks to the easy-to-use iPod adapter "Drive&Play" from harman/kardon the driver can enjoy the music stored on his iPod in addition to listening to radio, CD's and DVD's.
There's no such thing as too much power and thus the Mustang from offers not just copious amounts of same under the hood but also in the interior. A total of four JBL amps, types Px300.4, Px600.2 and A6000GTI, drive the speakers with no less than 10,000 watts of power. A bigger alternator and five Optima Yellow Top batteries ensure the stereo system's electrical health even at full volume.
The best was also barely good enough when it came to the integration of the loudspeakers: None other than installation specialist Renato Rivic from X-Dream-CarAudio implanted the distinguished products for JBL in the Ford Mustang. His futuristic shapes and choice of luxury materials add quite a bit more style to the interior. The vehicle now features a perfectly integrated real 5.1 surround system with top-shelf hardware from JBL. The speakers are located on the dashboard, in the doors, the space formerly occupied by the two rear emergency seats, and in the trunk: Two W15GTI subwoofers as well as three C508GTI, two GTO804 and one C608 GTI loudspeaker systems guarantee exceptional listening pleasure.

The GT 520 will spend the next 12 months as a show car at many exhibitions around the globe. Individual components of this vehicle are available for all current Mustang models.
