Martini Racing 911 Carrera RSR tribute: Classic Drive
The Martini Racing Carrera RSR 2.1 Turbo boasted the largest wing and widest hips of any Porsche 911 when it was raced back in the early 1970s. We experience what it must have been like to drive by getting behind the ‘wheel of a local tribute car.

I’m ensconced in the Martini Racing 911 Carrera RSR 2.1 Turbo tribute car’s Racetech racing seat with my legs almost parallel to the floor. I can hear road debris hitting the car’s undercarriage and I have to shout to talk to my passenger, the owner of the car. I’m intimidated, but immensely excited nonetheless.
In front of me is a plastic windscreen (a weight-saving measure), while the cabin is stripped out with only the necessary buttons and switches you associate with a race car. Above the windscreen, down the A-pillar and to my right, the silver tubes of the full roll cage leave no doubt that this is a pukka 911 race car.

With a quick glance in the rear-view mirror – as I won’t need it again on this drive! – I observe one of the largest wings in Porsche’s racing history. As I peer into the side view mirrors, the massive, widened rear arches and end tips of the rear wing come into view.
This car fills the road with its size and presence unlike any air-cooled Porsche 911 I’ve ever driven. I need to feed in enough throttle to stop the car from stalling but also let the racing clutch out as quickly as possible because any unnecessary slippage will damage it.

Driving the ‘Martini Racing 911 Carrera RSR’
The steering wheel conveys oodles of feedback; it goes light for only a brief moment before it stiffens up again and gives your arms a proper workout.
The Martini Racing 911 RSR tribute car’s G50 gearbox allows for quick and direct shifts, while the long metal gear lever and gear knob (with the very industrial-looking linkage system below) contributes to the solid shift action every time I change gear; it helps to ensure that you never miss a gear when shifting.

The Martini Racing 911 RSR tribute car is not happy when driven at anything less than full speed. There is a cacophony of mechanical sounds that emanates from the drivetrain in the rear of the car, while the smallest of throttle applications prompt a blowing and hissing sound from the turbocharged system.
If I briefly close my eyes, the experience is not far removed from that of the 993 GT2 Clubsport I experienced a couple of years ago. These mechanical sounds are so intense, that you also want to pull over and switch off the car, because it almost sounds as if there is no lubricant in the transmission!

As I press the accelerator pedal harder, and following a minor delay as the turbo gets up to speed, the Martini Racing 911 Carrera RSR tribute car positively surges towards the next corner with a rush of a modern-day supercar, only with much more noise, feedback and excitement.
Through the steering wheel, it is easy to experience how the front wheels sniff out any changes in the road camber and dive into bends like only a race car can. I realise that you need all your mental focus (and rather talented feet and hands) to get the most from this car.

Below 3 000 rpm nothing happens, but as I press on I can hear – and feel – how the tyres barely cope with the levels of torque, which are twisted through them as the full force of the engine presents itself with astonishing efficiency. It is a unique physiological experience; it feels as if the push is coming not only from behind you, but as if you are being shoved by something through your lower back.
And, it feels as if every ounce of the power and torque is on tap… if not more. Here, on this mountain pass, this Martini Racing 911 Carrera RSR tribute car feels like it will obliterate anything before it. Maybe it is a good thing that there are almost no other vehicles on this road.

On a public road, rolling on wet-weather racing tyres no less, full-bore acceleration upon corner exits is not on the cards, but between my time behind the ‘wheel as well as during a stint in the passenger seat while the owner, who races this car, was at the wheel, one thing became abundantly clear – this car is best-suited to the track!
History of this ‘Martini Racing 911 RSR’
However, this car’s origin is the same as all other 911 T production cars that left the factory in 1972. It rolled off the assembly line as a standard production car, but 45 years on, it is racing in South Africa.
Apart from the significant development process of this car – which we’ll get to in a minute – this Porsche 911 has been road-registered every year since 1972.

This car was already built (at great expense and with much effort) into a race car by one of the previous owners. At the time when we drove the car, the owner had bought the Martini Racing 911 Carrera RSR tribute car a few years before from a fellow 911 racer and enthusiast. Following his purchase, he competed in races occasionally but realised that a full rebuild of the car was required.
The result was that the car underwent a nearly 2-year restoration. It was stripped, the wiring was redone, the chassis was straightened up and the entire car was repainted. Then, the engine was taken out, stripped and rebuilt, and the cooling system was upgraded, to name just a few of the alterations. The engine was originally a 3.6-litre flat-6 engine from a 964-series 911 Carrera, which was turbocharged.

The owner explains: “I’ve campaigned it in this state, but then rebuilt it and enlarged the engine capacity to 3.8 litres. Other upgrades included race bearings, bespoke camshafts and a rebuilt turbo. The engine was converted to a turbocharged unit in Germany, where it also received special heads and porting.
“We redesigned the entire oil-cooling system. I didn’t like the number of oil pipes and reservoirs that were scattered all over the car and they also contributed to the heat soak in the cabin. So, we took some inspiration from older Cup cars and mounted the oil tank between the engine and gearbox.
The boost pressure for the turbo has been set at 0.8 bar. We also rebuilt or recommissioned every moving part, which came from Porsche, on the car. We’ve tried to keep the ‘RSR’ as original as possible.

After the rebuild, a dyno test revealed (very) impressive peak outputs of 413 kW and 680 N of torque. Let’s not forget, this power is delivered in a car that weighs a mere 1 250 kg.”
“It is, as a matter of fact, a little heavier than it should be, but you have to realise that a tremendous amount of strengthening has gone into the structure of the car,” he adds.
This is visible everywhere. Not only in the cabin, but below the bonnet there is a complete cross-strut bar, adding even more rigidity to the front of the chassis.

Equipment

The cabin is completely stripped and the only obvious modern equipment is the Motec digital screen. This small, but informative, screen displays the air temperature, fuel pressure, engine oil pressure, oil temperature, GPS speed and selected gear – pretty much all the necessary data and figures a racer would require pre-, during and post-race.
The revs are indicated by digital bars running at the top of the screen. There is the compulsory “ignition cut” switch, as well as brake bias and turbo-boost controller switches. The boost gauge is also visible, while the fire extinguishing system can be activated by the pull of a lever – it is an important function when you are strapped in with a 5-point harness and need to climb over so many pipes!

The NACA ducts are pure race car cues and that large rear wing is adjustable. As much as the rear wheel arches grab your attention, the same is true for those widened front arches.
It was the earlier owner who made the effort to build this race car and, in the early 2000s, started the long development process of converting his 911T into a race car. He started by installing lightweight parts, widening the body and the axle tracks, putting in a new floor etc.
The car was mostly developed on the Zwartkops racing circuit outside Pretoria.

“Racing is also something I was interested in, and over the years, through my participation in a few events and with the help of the previous owner of this car, I gained more experience. This is not the first Porsche race car I’ve owned,” the owner adds.
“Previously I’ve owned a 996 GT3 Cup car. I campaigned that for just over a year. We even did the 6-hour endurance race at Phakisa Freeway in the Free State, in which we came 2nd. When I sold that Cup car, I bought this car. Being a turbo, I like it a lot.”
Summary
It might be a bit of a novelty that this tribute car is still road-registered, but long may it continue. It is, without a doubt, one of the most exhilarating 911s I’ve ever had the chance to drive on the road. This homage to the Martini Racing 911 Carrera RSR 2.1 Turbo is a well-developed race car that pays tribute to the original, a car that formed the foundation of so many Porsche road- and race cars since the 1970s…
