The motor, a 600cm^3 flat-four cylinder from the well-known Suzuki GSX-R 600 sport bike, is mounted in the rear. A custom air-intake system was constructed in order to accommodate the 20mm air restriction from Formula Student. This entailed detailed air flow calculations and drawing from Formula 3 experience to achieve 80 HP despite the air restrictor. A motor dyno stand was constructed in order to carry out motor tuning. A motor management system from Walbro handles ignition timing and collects data from the various sensors on the car. This ECU allows us to collect precision motor data in order to optimize the ignition timing of the motor. This tuning process allows us to meet different criteria for more power as well as less fuel consumption. The motor's power/torque is transferred to the rear wheels over a particular Formula Student race differential, allowing seamless power transfer at high speeds while turning. In the curves the car must withstand large amounts of horizontal gravitational force. In order to combat this, the oil supply of the Iltis 08 uses a dry sump system that's been frequently used in the Motorcycle Race Industry for over 10 years. The front and rear suspension hangs the wheels using a fully-adjustable triangular pull-rod system. This is coupled with fully-adjustable Gas dampers, allowing the car to be fully tuned to any circuit. Hoosier tires are mounted on 13" magnesium wheels from BBS. The tires from Hoosier offer a supremely soft compound to keep the car in control in curves and produce faster lap times. "He who brakes later is faster longer!" - to fully achieve take advantage of this golden rule of racing, 4-piston Wilwood calipers have been coupled with 246mm discs for outstanding braking performance. In the rear 2-piston calipers mounted to 220mm discs give a good starting point for full-car brake balance. The brake balance is fine-tuned at the pedal, which is in turn controlled by a knob in the cockpit. This allows the driver to set brake balance to preference while driving! The bodywork of the car consists exclusively of carbon fiber. The individual parts use a pre-impregnated carbon fiber weave that have been finished under pressure and heat in an autoclave. The long-term Formula 1 experience and know-how of our partner UBC helps us achieve the perfect skin for the car, keeping the weight low and the quality high. The ergonomics of the car have been designed to the T. The tube frame's geometry is a perfect mixture of driver-size and rulebook, offering the capability for under-5-second driver entry and exit. Thanks to the removable steering wheel and perfectly-fitted pedal system the Iltis 08 can accommodate a driver up to 1.9m tall. The seat position is heavily reclined, keeping the center of gravity of the driver low to the ground. The Iltis 08 was built with the driver in mind. A large, fully-configurable LCD in the center of the steering wheel makes it possible to keep things in the cockpit very simple; instrumentation is kept to a minimum. Sequential shifting is achieved with switches in the grips of the steering wheel, giving the driver shifting possibilities with almost no movement whatsoever. The seat of the Iltis 08 is outfitted with a modular foam-pad system, also to be found in the airline industry. A six-point racing harness ensures the utmost in safety during the events. |
