It was the first and only K3 car to be delivered to the US by the end of 1979. The car won the 24 Hours of Le Mans race and was immediately purchased by the Whittington Bros, who fell in love with it. Curiously, they had to keep the secrets secret! The engine was a classical air-cooled six cylinder 3,0L twin turbo, fed by a Bosch mechanical injection. It had a four speed synchronized gearbox. Suspension was MacPherson strut in front, semi trailing arms in back, with coil springs all around. Large ventilated discs were used on all four wheels. The front fenders had been radically reshaped and were completely different from the original car. The rear was even more radical, with a second window added to the original one above it. The rear wing was much more bigger than the original one. The engine sported an air to air intercooler, which was supposed to maintain the power to its level throughout any race, instead of fading when heat built. Fresh air was ducted through. Two separate ignitions were used to fire each cylinder plug. Backup systems were used and deemed necessary for this kind of racing. The power output was estimated around 700bhp. A stiffening of the chassis was also probably one of the undisclosed improvements. Lightness was one of the Kremer priority, but IMSA competition required a better rigidity. Many adjustments could be made directly from the cockpit, from the boost knob to the anti-sway bar. The car was very fast, but required very skilled drivers. The Whittington Bros were good drivers and garnered a pair of victories in 1979. Was the K3 a copy of an experimental factory racer? Some of the Porsche people told so. The car was clearly the class of the field and would later become the car to own. By 1980, many of them were entered, with Dick Barbour hiring John Fitzpatrick who took the IMSA crown.
