Porsche 911 Carerra RS 2.7 (1973-74)

The Porsche 911 Carrera RS 2.7 (1973-1974) is a classic and highly revered model, but like any vintage car, it has its share of common faults:

1. **Engine Issues**: The 2.7-litre engine was known to be at the limit of its development, leading to problems such as worn intermediate gears and failing camshaft chain tensioners¹. The magnesium engine cases could warp, and head studs were prone to pulling out³.

2. **Valve Guides**: The valve guides often wore out prematurely, sometimes within 50,000 miles³.

3. **Corrosion**: Rust is a significant issue, particularly in the bodywork and undercarriage, due to the car's age and the materials used at the time¹.

4. **Heat Management**: The increased engine displacement and heat output could be too much for the magnesium block, leading to reliability issues⁴.

Despite these faults, the Carrera RS 2.7 remains a highly sought-after model due to its performance and historical significance. If you're considering purchasing one, a thorough inspection by a specialist is highly recommended.

Racing
The Porsche 911 Carrera RS 2.7 (1973-1974) had a notable racing history. Here are some key events and achievements:

1. **1973 24 Hours of Daytona**: An RSR version of the Carrera RS 2.7, driven by Peter Gregg and Hurley Haywood, won with a 22-lap lead.
2. **1973 12 Hours of Sebring**: The same drivers, along with Dave Helmick, secured another victory.
3. **1973 Targa Florio**: Herbert Müller and Gijs van Lennep won this challenging race.
4. **1973 24 Hours of Le Mans**: Müller and van Lennep finished fourth overall.
5. **1973 International Race of Champions (IROC)**: Roger Penske fielded 12 identical 911 Carrera RSR 3.0 cars for this event.

The Porsche 911 Carrera RS 2.7 had a remarkable performance in endurance races, solidifying its reputation as a formidable competitor. Here are some highlights:

1. **1973 24 Hours of Daytona**: The Carrera RS 2.7, in its RSR configuration, won the race with drivers Peter Gregg and Hurley Haywood. This victory was significant as it showcased the car's durability and speed over a grueling 24-hour period.

2. **1973 12 Hours of Sebring**: The same driver duo, along with Dave Helmick, secured another win for the Carrera RS 2.7. This race further demonstrated the car's reliability and performance in endurance racing.

3. **1973 Targa Florio**: Herbert Müller and Gijs van Lennep drove the Carrera RS 2.7 to victory in this challenging Sicilian road race. The Targa Florio was known for its demanding course, making this win particularly impressive.

4. **1973 24 Hours of Le Mans**: The Carrera RS 2.7 finished fourth overall, driven by Müller and van Lennep¹. Competing against prototypes and other high-performance cars, this result highlighted the 911's competitiveness in one of the world's most prestigious endurance races.

The Carrera RS 2.7's success in these endurance races was due to its combination of lightweight construction, aerodynamic design, and powerful 2.7-litre flat-six engine. These factors made it a dominant force in the early 1970s racing scene.

The Porsche 911 Carrera RS 2.7 is renowned for its distinctive design features that set it apart from other models of its time. Here are some key highlights:

1. **Ducktail Spoiler**: One of the most iconic features, the "ducktail" spoiler was designed to reduce lift at high speeds and improve stability¹. This was the first time a rear spoiler was used on a production Porsche, and it became a defining characteristic of the RS 2.7.

2. **Lightweight Construction**: The RS 2.7 was designed with weight reduction in mind. It featured thinner body panels, lightweight glass, and minimal interior trim². The result was a car that weighed just 960 kg (2,116 lbs) in its lightest configuration.

3. **Flared Wheel Arches**: To accommodate wider wheels and tires for better grip and handling, the RS 2.7 had flared wheel arches³. This gave the car a more aggressive stance and improved its performance on the track.

4. **Aerodynamics**: In addition to the ducktail spoiler, the RS 2.7 had a front air dam to reduce drag and improve airflow¹. These aerodynamic enhancements helped the car achieve higher speeds and better stability.

5. **Engine and Performance**: The RS 2.7 was powered by a 2.7-litre flat-six engine producing 210 PS (207 hp)¹. This engine, combined with the car's lightweight construction, allowed it to accelerate from 0-100 km/h (0-62 mph) in just 5.8 seconds and reach a top speed of 245 km/h (152 mph).

6. **Interior**: The interior was stripped down to the essentials to save weight. Features like rear seats, carpets, and even the clock were omitted in the lightweight "Sport" version². Customers could also opt for lightweight bucket seats instead of the standard sports seats.

These design features made the 911 Carrera RS 2.7 not only a formidable race car but also a highly desirable road car. Its combination of performance, lightweight construction, and distinctive styling has made it a legend in the automotive world.
