2006 Geiger Mustang GT 520
22.09.06 – 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 178 mph (287 km/h), and in addition to racing-inspired body styling painted a hot Geiger orange offers an exclusive interior with 10,000-watt sound system. The show car Mustang GT 520 from Geiger, 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 Geiger’s performance tuning of the Mustang GT V8 engine. Displacement was increased from 4.6 to 5.2 liters (317.3 cu in), and the engine was extensively reworked. Precision-machining of both cylinder heads, installing sport camshafts and reinforcing the valvetrain are part of the Geiger 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 415.2 ft lbs (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 Geiger Mustang GT 520 delivers exceptional performance: The sprint from 0 – 100 km/h takes just 4.2 seconds; top speed is 178 mph (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 Geiger 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 Geiger 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 Geiger 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 Geiger 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 Geiger rocker panels round out the sport package for the latest Mustang models.
The spectacular appearance is further enhanced by multi-piece Geiger 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 Geiger coil-over suspension. Firmer damper settings and a ride-height lowering of up to 50 millimeters lend the two-door even more agile handling. Geiger 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 Geiger 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 Geiger 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 Geiger 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.
