964 Cup

The Porsche 964 Cup (1990-1993) represents the first purpose-built 911 Cup racing car for Porsche's one-make Carrera Cup series. The 964 Cup features an air-cooled 3.6-liter flat-six producing approximately 260 horsepower with optimized engine tuning. Power is delivered through a 5-speed manual transmission to the rear wheels with limited-slip differential. The 964 Cup includes comprehensive racing modifications including roll cage, racing seats and harnesses, stripped interior, racing suspension with adjustable dampers, larger brakes, lightweight flywheel, and oil cooler. Weighing approximately 2,535 pounds, the 964 Cup achieves strong power-to-weight ratio for competitive one-make racing. The control formula ensures equal equipment across the field, with sealed engines and standardized specifications. The 964 Cup served as the foundation for Porsche's immensely successful one-make racing series, providing competitive wheel-to-wheel racing with comprehensive manufacturer support and identical equipment where driver skill determines results.
