nou die oude mustang is mooi maar met deze nieuwe vind ik mezelf alles behalve rondrijdend in een rip off
The "Five Liter" Is Back
The foundation for the Mustang GT-R's race-prepared 440-horsepower engine is the new 5.0-liter "Cammer" crate engine from Ford Racing Performance Parts. The engine is rooted in the MOD 4.6-liter four-valve V-8 engine family. However, the motor's flanged cylinder liners help provide 94mm (instead of 90.2mm) cylinder bores, creating a full 5.0 liters of piston displacement.
And while the motor employs the SVT Mustang Cobra’s forged crankshaft with six-bolt mains and Manley "H-Beam" connecting rods for superior strength, the high-strength Ford Racing block features design reinforcements and a revised material for added strength and high-output durability. The block is specially reinforced in the crankcase web areas for high torque loads.
Other key differences include forged pistons, an 11.0:1 compression ratio, ported heads, higher-lift cams and beehive-shaped valve springs. The crate engine also features higher-flow fuel injectors and a magnesium, variable-geometry intake manifold.
The 5.0-liter "Cammer" engine comes with a custom oil pan and features custom-fabricated Tri-Y headers and crossover.
Helping put the power to the ground is the Ford Racing-supplied TTC T-56 six-speed transmission linked to the engine through a heavy-duty clutch and flywheel assembly. Power exits the transmission through a custom metal matrix composite aluminum driveshaft into a race-specification differential with a 4.56:1 final drive ratio.
The "Cammer" was introduced at the Specialty Equipment Manufacturers Association show in 2002. The engine in the GT-R is identical to the crate engine, with the exception of camshaft timing, which was modified to produce more high-end horsepower for track use.
Proven Race Chassis
The Mustang GT-R benefits from the 2005 Mustang’s race-inspired chassis, developed and tuned by engineers with Ford Racing engineering experience or a passion for weekend track time. The Mustang’s race-bred suspensions, near 50-50 weight distribution and ultra-stiff body structure, are just the beginning of Mustang GT-R’s credentials.
"The GT-R is the ultimate expression of the Mustang platform," says Hau Thai-Tang, 2005 Mustang chief nameplate engineer. "Mustang spans more of the market than almost any other car – from an under-$20,000 V-6 to a race-ready car in the $40,000 range. The Mustang GT-R shows how we can expand that unmatched reach with the all-new platform."
Track time – at drag strips and on road courses – was a critical part of the 2005 Mustang’s development, as chassis engineers pushed prototypes to the limit in search of the perfect power-and-handling blend.
"We spent countless hours refining this car on development drives and at the track," says Mark Rushbrook, 2005 Mustang vehicle development manager. "The car has been to the Nelson Ledges road course in Ohio several times for 24-hour runs and has spent months on Ford's straightaways and handling courses at our proving grounds in Arizona, Michigan and Florida."
Soon after the 2005 Mustang’s world reveal in January, race engineers quickly began building on its solid foundation. The Mustang GT-R concept's chassis was fully stripped down to the body shell to receive custom reinforcement and structural improvements for driver safety on the racetrack. A roll cage was added, along with a Sparco-brand racing seat with a five-point safety harness.
The production suspension geometry is retained, but key parts were replaced to reduce weight or provide additional strength for the rigors of racing. Suspension pieces, including the K-member, are made of lightweight chrome-moly tubing. The race-proven dampers are coil-over, fully adjustable units featuring remote reservoirs. A strut tower brace increases structural rigidity.
Rounding out the chassis package are huge, race-proven Brembo brakes. The front features 14.3-inch rotors with six-piston calipers; the rear has 13-inch rotors with four-piston calipers. Linking the whole package to the racetrack are 20-inch wheels and racing slicks provided by Pirelli. Tire sizes range from 275/35 in front to 305/30 in the rear.
The Mustang GT-R is engineered with modern aerodynamics principles, including a massive front airflow opening and carbon-fiber belly pans that reduce underbody air turbulence.
Concept to Reality
Although the Mustang GT-R is a concept, the car was engineered to perform at racing speeds with parts currently available to weekend racers through the 2004 Ford Racing catalog.
The 5.0-liter EFI "Cammer" crate engine, including the wiring harness kit, will sell for an MSRP of $14,995. The "Cammer" engine takes the guesswork out of installation projects by offering a choice of several length 5.0-liter, 4-valve modular wiring harness kits created specifically to cover the most popular engine swap configurations.
What’s more, harness kits – which include the powertrain control module (PCM) – provide all the necessary electrical connectors, including end terminals, a fuse box, a power distribution box, as well as switch connectors and fuel pump relays.
The roll cage, rear spoiler and some chassis components are all being considered for further development.
