    Case history snapped up

    When we are putting the magazine together each month, we frequently ponder over which of our Case histories we would most like to own, and the Audi quattro in the February issue found a lot of favour.

    We were not alone in our appreciation, either, as its now-former owner Dr Jonathan Davies told us: “I had firm interest from three people as soon as the magazine came out. I had offers of deposits, and people wanting to view the car at various times, so I took a bold decision: not an auction but a race! “I said the first person to deposit the full amount would own the car.

    One declined to buy without seeing it (fair enough). Two wanted to continue, and I received notification of a transfer after close of business the same day, which translated into funds in my account the following morning. The new owner came up, checked over the Audi, and drove off happy. Good car, good write-up, good price and a good deal all round!”

    SPORT QUATTRO REP GET SHORTY Slick #SWB rep packs 509bhp / Stunning, 500bhp replica


    This Lamborghini-coloured Sport #Quattro #replica has been transformed from rough and ready into a 509bhp, road-legal track toy.

    Celebrated automotive restoration and tuning outfit, Retropower, has long been recognised as a force for good that takes on projects that start with tired, broken and rotting vintage vehicles and end with glistening, modified and mechanically sound high-horsepower masterpieces. Needless to say, we were excited to hear that the latest fettled fourwheeler to roll out of the company’s Leicestershire workshop is wearing an Audi badge.

    The car in question is a #1983 quattro that at some point in the past had been subjected to short-wheel base chassis remodelling by renowned #Audi specialists, #Dialynx-Performance. The Swindonbased firm has been a supplier of aftermarket tuning components for turbocharged Audis since its inception in 1988, but Dialynx is perhaps best known for its many Sport quattro conversions.

    Developed for #Group-B rallying in the mid 1980s, the Sport quattro featured an all-alloy 2.1-litre 20-valve engine sat inside a lightweight body shell comprising carbon-Kevlar panels and a windscreen rake borrowed from the Audi 80. In order to get rid much of the bulk that the manufacturer deemed to be an obstacle when competing against the rally-ready chariots of rival car makers, the Sport’s chassis was made considerably shorter than that of the ‘regular’ wheelbase rally quattro that preceded it. This ditching of metal delivered reduced understeer, more responsive handling and quicker turning, while the large body panels allowed for the use of bigger wheels and an increased track width.

    A couple of hundred road-going Sport quattros were produced for homologation purposes, but buying one today will set you back a serious amount of dosh (over £100k), not to mention the horror of the associated running costs. This is where Dialynx Performance steps in – the company has transformed many factory quattros into Sport replicas over the years, resulting in what is claimed to be a car that is virtually indistinguishable from the model that it mimics.

    Furthermore, Dialynx says that its replicas offer lucky owners tameable levels of performance as opposed to the uncompromising aggression produced by genuine Group B belters.

    “I’m led to believe that the Audi that made its way into our workshop was the third quattro that Dialynx had converted to Sport spec,” recalls Retropower co-founder, Callum Seviour. “Sadly, time hadn’t been kind to the car, and we discovered a huge amount of work that needed to be done in order to bring it back to its best,” he says. The striking body kit applied to the race-inspired rep was just one of many areas in need of attention. That said, a cosmetic overhaul was all that the car’s owner was prepared to commission until he could be sure that Retropower’s work was of a standard that he was happy with.

    “I guess you could call it ‘testing the water’!” laughs Callum’s brother, Nat. “We stripped the car, treated it to new subframe mounting points, removed and replaced its roof, built a new supporting roof frame, double-skinned its chassis legs, restored its body panels and bonded the corrected wide-arch kit into place before covering every part in a coat of primer. We were about to follow up with a lick of sparkling grey lifted from the Lamborghini colour catalogue when the quattro’s owner signalled his approval for us to start a long list of mechanical upgrades!” he confirms.

    Ordinarily, Retropower would take care of any spanner wizardry and/or fabrication work that needed to be carried out on one of its customer’s cars before tackling aesthetic updates, but the instruction that it was given with regard to the Audi forced the Seviour boys to work in an unorthodox manner. “The car’s owner was thrilled with the revitalised appearance of his ride,” continues Callum. “This gave us the green light to strip and rebuild the 2.2-litre ‘RR’ five-cylinder powerplant that sits beneath the vented bonnet up-front, although requested modifications that included a relocation of the engine’s cooling system and a boot-mounted dry sump kit forced us to cut away at metal that we’d only just prepared for paint!” he groans. Nevertheless, the 20-valve lump was carefully inspected before a period of planning that would transform it into an absolute monster. Not that the work involved in achieving such a feat was as easy as we might have made it sound...

    The car’s inline-five had suffered severe mechanical failure at some point in the recent past following work that a third party had undertaken on behalf of the owner. Subsequently repaired under warranty, the revised nuts and bolts were supposed to be producing in excess of 500bhp, but the condition and performance of the engine that Retropower were asked to work with casts doubt over that figure. Indeed, a sump populated by metal particles, a cracked cylinder head, a weeping head gasket, worn bearings and a mismatched piston that was making contact with a valve face all pointed towards what can be politely labelled as a ‘bodge’, and that’s without mentioning the serious lack of grunt that the car was producing under load.

    “We reground the engine’s billet crankshaft, machined all piston pockets so that they matched one another, and we sourced a new head before enlarging and smoothing its ports,” Callum tells us. As many original parts were retained as possible, with CNC polishing and restoration being employed to ensure the continued use of expensive equipment that was considered to be perfectly serviceable, while fuelling upgrades included twin Bosch high-flow pumps and 1000cc #ASNU-injectors .

    A Wagner Tuning inlet manifold and a chunky #Garrett GT40 turbocharger were called upon to work alongside a side-exit stainless steel exhaust system in the airflow department. Routing of the custom pipework demanded significant modifying of the Audi’s floor. Further metalwork involved the creation of a custom rear bulkhead and channelling for water pipes that travel the length of the car and back now that its cooling and lubrication systems sit in its boot space.

    A roll cage was already present, but door bars and diagonals were literally left hanging. “We were shocked to see that such an important safety device was so poorly fitted inside the car!” gasps Callum. “To counter this worrying discovery, we fabricated a comprehensive multi-point cage that travels through the dashboard, triangulates and attaches itself to key structural components throughout the chassis,” he explains.

    Talking of which, suspension and braking upgrades were already evident in the form of modified struts (to allow for coilovers) and braces, Koni damper inserts and Tarox six-pot stoppers, yet the Retropower touch bettered these key features thanks to the appointment of SuperPro polybushes and a Wilwood pedal box. The latter inhabits a cabin that also boasts Recaro Pole Position buckets, a flocked dash, Stack gauges and an SPA KitDash that occupies space once reserved for standard quattro clocks.

    Even though the completed car is used as a track toy, it remains road legal. This surprising fact meant that its owner wanted a show-quality finish to what is essentially a motorsport body kit. To that end, masses of effort went into filling and block-sanding what would otherwise be “ripply” panels before the Lambo paint was finally splashed across the flawless build.

    Azev A wheels coated in a similar shade were already in place when the Audi arrived at the Retropower workshop, unlike this awesome VAG machine’s current power output. “I’m delighted to be able to say that the car is now producing over 500bhp following the huge amount of time and effort that my team has spent on the project,” beams Callum. He’s being typically modest; despite a dyno printout displaying an impressive 509bhp and 410lb per foot of torque (delivered by a custom map on a MoTeC M48 ECU), this fantastic four-wheel drive pocket rocket has the potential to knock on the door of 600bhp if its owner ever fancies investing in a transmission upgrade.

    In the meantime, running a powerful engine well below its top end abilities should result in a safe, reliable delivery of ponies both on and off the track. Retropower, we salute you!

    RETRO – UR quattro #1984 / #1987 #Audi-Quattro F , G, H… / #Audi-Quattro-F / #Audi-Quattro-G / #Audi-Quattro-H / #Audi-Ur-quattro / #Audi /

    Darron Edwards continues his account of the development of the Ur quattro, with a look at the F, G and H series models between 1984 and 1987…

    Cosmetically, the Ur quattro had remained virtually unchanged since its introduction in 1980, but all that changed in 1984 when both the interior and exterior of the car received some subtle upgrades that made all the difference. Bringing the quattro right up to date, most of these changes remained until the final incarnation of the car seven years later.

    The three chassis types that spanned 1984 to 1987 were the last to use the tried and tested 200 PS ‘WR’ engine and so this was the most settled period of Ur #Quattro production, when the car remained virtually unchanged, inside and out.

    The #Audi-Quattro-FA chassis was introduced in August 1984 and the cosmetic changes were obvious straight away, with the front and rear end of the car receiving a more modern look. At the front, the one-piece Cibie headlights were retained but they now had sloping glass lenses, coupled with a re-designed sloping front grille and headlight trims. This gave the front end a much more streamlined look and it did indeed improve the aerodynamic co-efficient of the car.

    At the rear, a revolutionary design was used, with the tail lights now ‘smoked’ black. A very clever manufacturing process was used, where the lights appeared black from a distance but closer inspection shows that a coloured shroud covered the bulb so that, when it illuminated, the lens would appear to change colour briefly.

    The prismatic strip that runs horizontally across the lower part of the boot lid also received the smoked black treatment, while the top of the boot lid which up until now had been painted satin black, regardless of body colour, was now painted the same colour as the rest of the car.

    The rear skirt that surrounds the bumper was also re-designed and it now had an integrated mudguard to prevent dirt spraying up the side of the car from the wider 8-inch wheels.

    Another revolutionary design on this model was the use of flexible additive in the paint that was applied to the rear rubber spoiler. This meant that it could be colourcoded and, together with all the other new features, it gave the rear end of the car a radical and more modern new look. This new look was eventually copied by most motor manufacturers on a wide variety of cars and even the Ford Capri would get its own version of smoked rear lights and prismatic rear panels were offered as aftermarket accessories for many models.

    Up until now, the rear badging had been achieved by the use of dot matrix decals, finished in either silver or black (dependent on body colour) manufactured by 3M. These were replaced by new three-dimensional plastic badges, with a chrome or black finish. The size and shape of the font used was the same, but the position of both the ‘Audi’ and the ‘quattro’ badge was raised slightly compared to the original decals.

    A new range of body colours was introduced in 1984, with Mars red now replaced by a deeper and more striking red called Tornado red. It suited the new cosmetic changes very well and became the definitive colour of this period of Ur quattro production.

    The decals in the rear side windows were also re-designed. They were originally silver dot matrix, but from the FA chassis and up until the JA they were now a dark brown colour and of a hollow / outline design. This was done to match the rear de-mister that bore the ‘quattro’ legend – when the rear screen element was heated, the famous name would melt the ice and slowly appear in the rear window. A very cool touch!

    Inside the car, a new look was also applied. Brown was now replaced by black, and plenty of it! The new dashboard that made its debut on the previous model was now finished in black vinyl to match the new carpet and other interior trim. It had a new centre console panel that now featured an oil temperature gauge and voltmeter and also a neat two-stage, rotary diff lock switch that illuminated two green LE Ds set in a graphic of the quattro drivetrain.

    A smart grey tartan cloth with a fine red and blue pinstripe was introduced for the front and rear seats and this new cloth was also applied to the front door panels and rear quarter trim. It was coded ZN and called ‘Graphite Eton Flannel’. This is my personal favourite interior trim and was fairly hard-wearing, apart from the upright bolster on the driver’s seat. I regularly repair these with a new black cloth panel.

    The digital dash that was fitted from 1984 was now green. On some cars you could alter the way that the rev pointer appeared. It was possible to switch between a dual finger pointer or a ‘snail trail’ type pointer. This could be done by selecting ‘fuel range’ on the MFD and then holding down the re-set button on the computer switch. The revcounter, clock and gauges could also be turned off by pushing in the dash dimmer switch, although this is a feature that I’ve seldom used. This new system replaced the turquoise coloured digi-dash unit from the previous car. The handbrake warning light was also removed from the driver’s side under panel and now fitted in the binnacle.

    The wiper stalk on the steering column now only moves up for wiper selection (early quattros had the intermittent position down one click). First position is now for intermittent wipers and then the next two clicks for slow and fast wipe. This newly designed stalk also contained the switch to operate the voice check system.

    Most G and H chassis cars were fitted with the standard tilt sunroof. This could be tilted by 25 degrees or, by pulling two clips, completely removed and stored on two special runners in the boot. It’s worth noting that most FA chassis cars that I’ve seen don’t have a sunroof.

    With the introduction of the HA chassis came a couple more safety improvements. The front brake callipers were redesigned and the front brake discs enlarged. The callipers were now twin piston – a big improvement on the previous single-pot units. The discs were thicker and larger to complement the new callipers.

    The second safety improvement was the introduction of twin side light and brake light bulbs in the rear light clusters. This was done without the need for new rear light units. A simple modification to the bulb holders was enough to greatly improve the visibility of the brake lights, especially as the rear lenses were now black.

    As far as spare parts are concerned, these three chassis are probably the easiest of all quattros to source parts for as they were the most numerous of all Ur quattros. I own two #Audi-Quattro-GA chassis cars and I love driving them – I feel completely at home in their comfortable interior and I enjoy the green digital dash. This was obviously not the case for everybody, though, as Audi would change all this in the next incarnation of the Ur quattro...
