How Did the 1966 Shelby Cobra 427 Super Snake Achieve Its Unmatched Speed and Power?
The 1966 Shelby Cobra 427 Super Snake is a legendary car that cemented the reputation of the Shelby brand as a manufacturer of some of the most powerful and fastest sports cars of its era. While the basic design principles were not entirely new, combining a high-performance engine with lightweight materials and advanced engineering did create a car that would push the boundaries of what was possible in street-legal vehicles during the 1960s. This article delves into the key features and innovations that made the 1966 Shelby Cobra 427 Super Snake so fast and powerful.
The Age-Old Formula of High-Torque Engine and Lightweight Body
Carroll Shelby applied a well-known formula to achieve the performance that the Super Snake was renowned for. He installed a powerful and high-torque engine into a lightweight sports car. In the case of the Shelby Cobra, the chosen engine was the Ford 427 race engine. This motor was already well-regarded for its power and reliability in racing applications, and when paired with the lightweight AC Cobra body, the potential for speed and power became clear.
Advanced Engineering: Strengthening the Chassis and Suspension
To handle the immense power and torque provided by the 427 engine, Shelby made significant enhancements to the car's chassis and suspension. The lightweight yet robust tubular steel frame and fully independent suspension system were designed to withstand the stresses of extreme acceleration and cornering. This combination allowed the Super Snake to maintain its balance and stability even under the most demanding driving conditions, which would have been impossible for a conventional road car to handle.
Handling the Aerodynamic Limits
Despite the superb engineering, the Super Snake encountered a practical limit at around 140 mph due to aerodynamic factors. At such high speeds, air resistance became a significant challenge. Shelby knew that further increases in top speed would require a solution, leading to the development of the Shelby Daytona.
Power and Performance Overview
The 1966 Shelby Cobra 427 Super Snake was no slouch, even without the external modifications like the Shelby Daytona. The car, weighing in at 2,600 lbs, with a rated 450 HP, could complete the 0-100-0 sprint in under 25 seconds, assuming modern Michelin Pilot Sport tires and brake pads. This performance would be significantly better with the latest technology.
Unmatched Speed and Power Through Supercharging
The two 1966 Shelby Cobra 427 Super Snakes created with twin centrifugal superchargers brought the formula to a new level. These cars were rated at an unbelievable 800 HP, making them the epitome of automotive performance of the era. Unfortunately, only one of these cars still exists today, while the other met a dramatic end, pushing its owner over a cliff.
Conclusion
The 1966 Shelby Cobra 427 Super Snake stands as a testament to fusion of the right elements—powerful engine, lightweight body, advanced engineering, and proper driving skills. While the car was incredibly fast and powerful, it was too much for the street and most drivers. This unique combination of speed and power made the Super Snake a true icon, albeit one that was best left to professional drivers and racing conditions.
