1,054 hp Porsche 997 to attempt World Speed Record for Street-Legal Cars



MISSION 400 PLUS is attempting to to win the Blue Ribbon for the world’s fastest street-legal sports car next year, with a top speed of more than 400 km/h. Developed through collaboration with H&R, Jürgen Alzen Motorsport and engine tuner RS Tuning and the sports car is based on the Porsche 997. With a boost pressure of 1.5 bar the engine develops 1,054 hp / 775.7 kW at 7,700 rpm and a peak torque of 1,030 Nm at 5,800 rpm, yet, the record hunter meets stringent EURO IV emission limits.

The idea to tackle the world record was born in August 2006 at the Six-Hour Race on the Nürburgring: After the H&R-sponsored Alzen Motorsport Porsche 911 GT3 fell victim to an accident in only the second lap, team boss Jürgen Alzen and H&R marketing director Hardy von der Brake had time to discuss means to better demonstrate the technology transfer from motorsports to the development of sporty suspension components.

The idea quickly turned into the MISSION 400 PLUS concept, whose prototype now celebrated its world debut at the ESSEN-MOTOR-SHOW 2006. The three companies that have joined forces to turn this concept into reality have proven their potential in building super-fast sports cars numerous times before.

The experienced team of technicians from Jürgen Alzen Motorsport in Betzdorf is responsible for the technical design and for building the car. The engine is based on that of the latest 997-series Porsche 911 Turbo, and comes from RS Tuning. H&R contributes its immense know-how in the field of suspension design and setup.

Favorable aerodynamic properties are essential for a car that is designed to break the 400-km/h barrier. Minimizing frontal surface area is absolutely elementary, which is why Jürgen Alzen decided to lower the roof by 75 millimeters. At the same time the A-pillars were tilted back further by 5.5 degrees. To give the coupe a homogenous overall appearance the tilt of B- and C-pillars was adjusted accordingly. Special flush-mounted polycarbonate windows all around complete the roof conversion.

Also part of the MISSION 400 PLUS aerodynamics concept are numerous other modifications that were developed and tested in the wind tunnel. Among them are a long rear with pronounced separation edge and the absence of rain channels. Streamlined cowlings for the 18-inch BBS light-alloy wheels will reduce air turbulence on the vehicle’s sides during the record run.

De quién es el record ?? Del Bugatti Veyron ?? Había visto un programa de Top Gear en donde llegaron a 407 km/h

MISSION 400 PLUS, ese es el nombre que le han dado a este bicharraco cuyo objetivo es convertirse en el coche de calle más rápido del mundo, con una velocidad punta superior a 400 km/h. Ha sido fabricado por H&R, RS Tuning y Jürgen Alzen Motorsport, y se presenta en el ESSEN-MOTOR-SHOW 2006.

Jürgen Alzen Motorsport se encargó del diseño y de la fabricación; RS Tuning del motor, con base en el último 997 Turbo, y H&R de las suspensiones. El techo se ha rebajado 75 mm, y los pilares A se han desplazado 5,5 grados hacia atrás, con el ajuste correspondiente de los B y C. La aerodinámica se ha afinado por todas partes, incluyendo también las llantas de 18 pulgadas.

El motor se ha llevado de 3.6 a 3.8 litros, y le han cambiado los cilindros, con válvulas mayores, el turbo, el escape, y casi todos los componentes periféricos. Los turbos de geometría variable se ha sustituido por otros convencionales de mayor tamaño, la gasolina es de 100 octanos, y sigue cumpliendo la normativa de emisiones EURO IV.

A 1,5 bar, el motor da 1.054 CV a 7.700 rpm, y un par de 1.030 Nm a 5.800 rpm. ¿Será suficiente para batir el récord? Lo sabremos en la primera mitad de 2007, cuando tenga lugar el intento en el circuito de Nardo.

Cuantas libras es 1.5 BAR ?

21.75 psi

CHUZO!

No tiene ni retrovisores! eso debe bajar en un par de dècimas el Cx de ese 911T

cuando lo prueban?
