1995/97 Porsche 993 3.8 RSR. The cars history starts with the original owner contacting Jurgen Barth of Porsche in 12/20/1994. His request as an individual customer, was to purchase a new 993 SuperCup. As these were only being produced and sold to entrants in the European Porsche Cup series, his initial request was denied. Further requests to Alwin Springer, Director of Porsche MotorSports North America (PMNA) finally made the purchase possible and the sale was approved by Jurgen Barth in April 1995. The car initially offered was not white, but the original owner persisted in his request for Grand Prix white. His persistence paid off. This was the first 'permanent resident' 1995 993 Cup 3.8 delivered to the USA. The first owner of this 911 Cup 3.8 was John Ruther, the owner and President of NorthStar Motorsports in Lake Barrington, Illinois, and former President and current Director for the Chicago region of Porsche Club of America (PCA), as well as the longtime Chief Driving Instructor. It was raced in Porsche Club Amateur racing events and never raced professionally. During the 1996 race season while at Road America, John Ruther and Alwin Springer met to discuss developments for the 1997 version of the Naturally Aspirated (N.A.) Cup Car. In their discussions, Alwin told John about the new RSR engine. The new engine was extensively different from the prior version. The prior version was the M64/20 and the new version would be a M64/70. The prior version could not be upgraded and to be swapped out. In 1997 the car was returned to PMNA where a M64/70 version of the motor was installed. This engines output was 390 HP. Also installed by the factory was RSR bodywork and suspension components. Thus making this car the only 1995 tub Cup Car with the 3.8 RSR motor, suspension and bodywork, authorized and built by the factory. The original owner later upgraded to Evolution (EVO) bodywork and a slide valve induction system. The prior induction system was kept for use as needed at specific racetracks. The engines output now was 410HP. Slide valve systems are very rare and they require a special EMU to operate. This car is the most fully developed N. A. 993 Cup car authorized and built by the factory.
