    Battery protest falls flat…


    After the finish ceremony of the 2013 Acropolis Rally, Citroën Total Abu Dhabi lodged a protest against the three Volkswagen Polo R WRCs. The protest was dismissed, however, which means that Jari-Matti Latvala has not been deprived of his victory.
    Après la cérémonie du podium du Rallye de l’Acropole 2013, l’équipe Citroën Total Abu Dhabi a porté réclamation contre les trois Volkswagen Polo R WRC. La réclamation a été jugée recevable mais non fondée. Jari-Matti Latvala conserve sa victoire.
    Citroën’s protest concerned the spare batteries that the French make believed were carried by the three Volkswagen Polo R WRCs during Friday evening’s stages. Effectively, the regulations only permit a spare to be in the car for ‘parc fermé’, before it is removed after the day’s first service halt.
    An initial protest was drawn up against the N°7, N°8 and N°9 Polos, but this was rejected by the stewards on the basis that it did not comply with the correct procedures. Another two, separate protests targeted more directly the Volkswagen Motorsport ‘I’and Volkswagen Motorsport ‘II’ teams and were accepted. The stewards deliberated late into evening night but, shortly after midnight, the protests were dismissed as unsubstantiated.
    Thanks to his victory in Greece, Jari-Matti Latvala (74 points) has moved into second place in the provisional Drivers’ standings, behind his team-mate Sébastien Ogier (126). Loeb (who won this weekend’s Rallye du Chablais in Switzerland with his wife) is still on the podium ahead of Mikko Hirvonen (60) and Thierry Neuville (50). Qatar M-Sport WRT’s Mads Ostberg (46) and Evgeny Novikov (31) are respectively seventh and eighth, behind Dani Sordo (47).
    In the Manufacturers’ championship, Volkswagen Motorsport has extended its lead over Citroën Total Abu Dhabi WRC from 14 to 18 points.
    La réclamation de Citroën portait sur des batteries de secours qui auraient été transportées dans les Volkswagen Polo R WRC pendant les spéciales du vendredi soir. Or, le règlement autorise la présence de batteries de secours à bord uniquement en parc fermé. Elles sont retirées à la première assistance matinale.
    Une première réclamation dirigée contre les équipages des Polo R WRC n°7, 8 et 9 a été rejetée par le collège des commissaires pour vice de forme. Une seconde, à l’encontre cette fois des équipes Volkswagen Motorsport I et Volkswagen Motorsport II, a été acceptée. Les commissaires ont délibéré jusque tard dans la nuit. Il était minuit passé lorsque la décision est tombée : réclamation jugée recevable mais non fondée.
    Grâce à cette victoire, Jari-Matti Latvala (74 points) se hisse à la 2e place du championnat Pilotes derrière son équipier Sébastien Ogier (126 points), solide leader avec 52 points d’avance. Loeb (vainqueur du Rallye du Chablaisce week-end avec son épouse), est toujours sur le podium provisoire devant Mikko Hirvonen (60 points) et Thierry Neuville (50 points). Les deux pilotes officiels Qatar M-Sport WRT, Mads Ostberg (46 points) et Evgeny Novikov (31 points) sont respectivement 7e et 8e derrière Dani Sordo (6e, 47 points).
    Au classement Constructeurs, Volkswagen Motorsport augmente son avance sur Citroën Total Abu Dhabi WRC : l’écart était de 14 points avant la Grèce, il est désormais de 18 points.

    Leaf-Blower Supercharging a 1978 Chevrolet Monza Spyder!

    On this episode of Roadkill, it's fun with Leaf Blowers. Experts on the Internet said it would never work. That's never stopped Freiburger and Finnegan, and this time on Roadkill the guys put the theory to the test: can hardware-store leaf blowers supercharge an engine and make power? Step one was buying a '78 Monza Spyder with a 305 V8 and a four-speed stick. Step two was to take it to the shop of HOT ROD Drag Week racer Jeff Lutz to tune it up, swap the engine to a 350, dyno test it with five leaf blowers, and do a whole bunch of needless burnouts. Step three was to drive the Monza to Willmington, Ohio, for the East Coast Timing Association's Ohio Mile event, a standing-mile race where they'd find out if leaf-blower power adds up to more speed in the real world. The outcome? Who really cares? Because on Roadkill, it's always about the adventure. And more burnouts.

    Suzuki has problems finding an exsisting MotoGP team


    froùm TWOWHEELSBLOG
    Randy de Puniet gave the Suzuki MotoGP a two-day shakedown test at Motegi and the Hamamatsu manufacturer will be testing in MotoGP’s Monday’s post-race test in Barcellona, before heading to Aragon for further testing.
    Davide Brivio is reportedly to become the team manager behind the effort and apparently has already found a couple places in Italy where to run the team from, the only thing missing - besides the burning question of who will be riding the new bike - is the ‘exsisting team’ that Suzuki will need in order to return to the championship in 2014, but this quest seems to turning out to be more difficult than one would have expected.
    According to Spanish website motocuatro.com Dorna suggested that Suzuki offer 1.6 million euros to buy their place into one of the private teams, but apparently no team - even if most of them are cash strapped and some aren’t even competitive - are willing to accept that price and are asking between five and six million euros.
    Supposedly trying to shaft Suzuki has not gone down well with Dorna - who subsidizes all the teams in various amounts - and could be thinking of increasing the MotoGP grid in in order to allow Suzuki to partecipate, which no doubt would make the Japanese manufacturer much happier because they would have more control and be on the same level of Honda, Yamaha and Ducati.

    HOLESHOT HERBIE: THE CANADIAN-SWEDISH-KIWI BUG


    In the mid 1960s an unassuming cherry red ’56 Volkswagen Beetle shook up the NHRA establishment. Cutting 13-second quarters on trap speeds approaching 100mph, EMPI’s iconic Inch Pincher was more than just a thorn in the side of the American V8-dominated institution – it was the machine that paved the way for a worldwide drag racing movement that half a century later is still going strong.
    So what better way to wrap up our VAG mini theme then, than look at one of its spiritual descendants – a part-modern, part-vintage ’68 Bug built for straight-line speed.
    It’s a truly global story too, because although this Herbie-themed creation now calls New Zealand home, the well-travelled machine was originally created and raced in Canada, but purchased by its new Kiwi owner out of Sweden.
    The first time I saw the Beetle was during the roll-in for this year’s 4&Rotary Nationals Show. Funnily enough, it was the first time its owner, Nigel Scott, had physically seen the car too, as the ship from Sweden it had arrived on after a couple of months at sea only docked in Auckland that morning. How he managed to get it through customs and off the port that quickly I’m not sure, but the car ended up just making it into the show in time.
    Although he was new to the car, Nigel’s definitely not new to VWs. Thanks to his Auckland-based business, Platinum VW Spares – a Volkswagen-specific auto dismantler and service centre – he lives and breathes the brand almost every waking hour.
    Having tried its hand at a wide range of motorsports, inevitably Platinum ended with a penchant to go drag racing. Originally, Nigel had plans to build a car from the ground up, but after crunching the numbers it soon became apparent that purchasing a pre-loved, turnkey racer would be a far more cost effective option.
    And what Nigel got for his money was a proven 10-second naturally aspirated package, originally built and campaigned by John’s Bug Shop in Ontario.
    Featuring a full tube-frame chassis incorporating a four-link rear suspension arrangement, it’s a purpose-built machine too. Here, with the one-piece FRP front clip, FRP doors and FRP rear fenders attached then removed, you can see how much actual steel ’68 Beetle there is left of the original car. Not much. Panels on, the Beetle tips the scales at just 580kg (1278lbs), which goes some way in explaining just how it’s able to scoot down the quarter mile rather quickly with not a huge amount of power on board.
    That said, the flat four hanging out in the back is an impressive looking and performing piece of engineering built around a Volkswagen Type 1 engine.
    When I say built around I’m using that term rather loosely, because it’s not hard to see that the engine is far from that that originally powered the ‘people’s car’. At its heart is an ARPM two-piece crankcase fitted with high-compression forged pistons, Carillo rods and a Scat 84mm stroker crankshaft pushing cubic capacity out to 2457cc. More obvious additions are the two giant Geers 62mm Terminator carburetors which flank race-prepped Autocraft cylinder heads fed by giant 50mm diameter intake valves.
    You gotta love the tuned-length stainless steel exhaust manifold and upswept Stinger tail pipe too. Temperature sensors are positioned in each of the branches, which of course give a good indication of the tune.
    Thanks to their rear-engine layout, Beetles like this one generally have no problem putting the power to the ground, nor achieving quick 60-foot times. In Herbie’s case there’s a custom-geared VW Kombi/Bus four-speed box, running through a Kennedy/Black Magic clutch to a custom full spool differential. On the business end, custom axles and Porsche CV joints run to Wilwood Wide 5 hubs and 15×8.5-inch Center Line Wide 5 wheels, wrapped in M&H Racemaster 8.5/26.0-15 slicks. There’s plenty of grip, which of course necessitates the use of wheelie bars (not fitted for our shoot) to go against the will of the front wheels and keep them firmly planted on the ground.
    It’s much more basic at the front, but no less exquisitely-executed, with an A-arm layout featuring drag-specific Lamb Components coil0vers. As evidenced by the small JAZ cell sitting up front, the Beetle only carries as much fuel as it needs to get down the strip.
    On a strict diet of 108-octane VP Racing C12 fuel, the motor screams its way to 9000rpm and throws down 292whp. Couple that with the scant kerb weight I talked about earlier and it’s easy to see why it’s gone 10.19 at 208km/h in the past.
    Although the Platinum crew are still very much coming to grips with the chassis set-up given the limited number of times they’ve had it on the track thus far, both Nigel and the Beetle’s primary driver, Allan, are pretty confident that there’s nine-second potential in the current guise. That result would put it on par with some of the quickest naturally aspirated Beetles on the planet.
    To be honest though, if I had this car in my garage I don’t think I’d be at all worried about how quick it did, or didn’t go. I can’t put my finger on it, but there’s something so right about a drag Beetle. Does anyone agree with me?
    I’ve waved my camera around in plenty of race car interiors, but this space has got to be one of my all time favorites. It’s pretty evident that there’s nothing here that doesn’t need to be, which of course has everything to do with weight reduction and nothing much else. But the build quality and attention to detail is some of the best I’ve ever seen.
    That, of course, includes the 4130 chromoly bar work that forms the skeleton of the car. Although details are thin on the ground, Nigel believes that the chassis was actually built in the USA before being finished off in Canada.
    As far as metal seats go, this one actually looks pretty comfortable. It’s seemingly been fashioned from a single sheet of aluminium too, and even features the same detailing as the floor and door panels.
    All 0f the electrical ancillaries are neatly mounted near the floor on the passenger side of the cockpit. Given the carburetors there’s no engine management system of course, but an MSD 7AL-2 for ignition control, and from Innovate Motorsports a TC-4 configured to measure exhaust gas temperature, and a DL-32 data logger.
    Here’s a look at the interior fabrication work toward the rear of the car and the Lexan polycarbonate windows, which are an integral part of the weight reduction programme. The air ducts in the rear side windows supply a cool breeze across the top of the engine where it can be sucked up by those carbs.
    Just hours after I finished up shooting the Beetle, the Platinum team began stripping it down for a ground-up rebuild over winter, starting with the engine. Even though he’s only driven the car a handful of times, it’s easy to sense Nigel’s enthusiasm for this project and ultimately where he’d like to see it end up.
    That is, with another car built to similar specifications as this one, but wholly engineered in New Zealand utilising the best local talent. It’s a likely prospect for the future, but in the meantime Nigel and his Platinum team are looking forward to the forthcoming 2013/2014 Kiwi summer season of drag racing which kicks off in October/November, and perhaps – if they’re lucky – a single-digit slip.
    So there you have it: a final conclusion to our VAG mini-theme. We’ve brought you a wide range of VWs, Audis and Porsches, from low-slung show queens, to motorsport monsters, showcased the history of these brands, and featured cars from their homeland, right the way to the other side of the world. And what better way to close it off than with this look at a modern take on a true Volkswagen classic; we’ve gone full circle and ended up back at the beginning. So what do you think? What’s been your favorite piece?

    Newport Pagnell's Greatest Hits: 1960s Astons for sale



    Aston Martin celebrates its centenary this year but, of all the eras, the DBs of the Sixties are the most widely celebrated classic Astons. We take a look at some examples currently on sale in the Marketplace.


    Aston Martin DB4: The first 'DB' of Newport Pagnell


    When the DB4 made its debut at the 1958 London Motor Show, it stunned the world – not only for its ‘quintessentially British’ looks (despite being styled by Italian coachbuilder Touring), but also for the revolutionary Superleggeralightweight construction process it employed under licence from its stylists.

    Initially equipped with an aluminium 3.7-litre inline-six, the DB4 had everything required of a 1960s sports car. Later variants (including a convertible) saw the oft-bemoaned overheating problems cured, while most early cars will have been retrospectively modified to address the problem.

    DB4s can be found in the Classic Driver Marketplace >> 



    Aston Martin DB5: The most famous car in the world



    The DB4 had been continually evolving, but 1963 saw the official introduction of the replacement DB5 model. Looking almost identical, the notable changes were the adoption of a 4.0-litre version of the inline-six, coupled to a new five-speed gearbox.

    Of course, the DB5 gained lasting worldwide fame courtesy of its inclusion in the Bond films. As a result, the car commands a price premium well above that of other Astons of the same generation.

    Aston Martin DB6: The quest for comfort



    Again visually similar to its predecessor (bar the more aerodynamically efficient Kamm tail), the DB6 this time made advances in the direction of greater comfort – further enhancing its credibility as a GT.

    A wheelbase extension and roofline lift turned the car into a genuine four-seater, while air-conditioning and power steering were offered as options for the first time. An automatic transmission could be specified at no extra cost.

    Aston Martin DB6 Shooting Brake: From Radford to FLM Panelcraft



    On several occasions, David Brown instructed his employees to build unique cars to his specific personal requirements. One of these was a DB5 estate; the resulting ‘Shooting Brake’ garnered so much attention that he struck a deal with Harold Radford to supply a limited run to meet customer demand.

    When production of the donor model ceased, Radford began using the DB6 as a base. FLM Panelcraft also completed a pair (albeit without retaining the Kamm tail) – one of which was ordered new by Innes Ireland, and is now up for sale in the UK.

    Aston Martin DBS: End of the Touring era



    Touring was enlisted to design the DB6’s replacement, but the proposal was deemed unsatisfactory and the styling moved in-house. The Italian coachbuilder went into receivership soon afterwards. William Towns was charged with developing an alternative, using a squarer, perhaps American-inspired form for the DBS.

    Meanwhile, development of Aston’s new V8 – previewed by the Lola Le Mans cars – was not ready as was hoped, so the DB6’s six-cylinder was retained until the arrival of the road-ready V8 in 1969.

    ORIGINS OF AMERICAN SUPERBIKE


     By 
    Photographer :  Tom Riles
    Eddie Lawson and Freddie Spencer
    We remember the beginnings of U.S. Superbike as wobbling, power-laden, four-cylinder, Japanese high-bar sit-ups in the hands of riding greats Reg Pridmore, Wes Cooley Jr. and Eddie Lawson. Yet the fact is that the first Superbike championship was won by Reg Pridmore on a BMW flat-Twin and Ducatis, Moto Guzzis and BMWs were to continue to win races, including Daytona. How could 80- to 90-horsepower Twins stay with 140-hp rocketships? The answers are: lighter weight, better handling, better brakes and, at least initially, preparation by experienced teams.
    One hundred and forty horsepower is useless even at Daytona if your chassis is so flexible at speed that you can’t pin the throttle. At twisty tracks like Sears Point and Loudon, four-cylinder power just pushed streetbike brakes into early fade and failure. Light weight boosted acceleration and direction changing. And, at least at first, the Twins were built by experienced people while the four-cylinder teams learned by doing.
    Superbike evolved out of a California production series that the AMA adopted as “Superbike Production,” initially, from 1973 to 1975, including engine displacements from 250cc to 1000 in separate races. This was intended to provide an everyman’s alternative to the GP-style 250 and Formula 750 pro classes, but the immediate popularity of one-liter four-strokes made them a major class for 1976. Pridmore’s championship on a BMW owed much to the fact that its builders at Butler & Smith had been racing the flat-Twins since 1974. Mike Baldwin’s 1976 Loudon win on a Moto Guzzi was also experience-based: from the shop of veteran Reno Leoni. Cook Neilson’s 1977 Daytona win on “The California Hot-Rod” bevel-drive Ducati drew on the resources of U.S. specialists like Webster Gear, dyno expert C.R. Axtell and airflow pioneer Jerry Branch. These European Twins all handled decently to begin with, had capable brakes and had previous history in racing.

    The four-cylinder bikes—initially just Kawasaki, and from 1978 onward Suzuki, as well—had not been designed with racing in mind. Increasing their power through engine modifications at first magnified their problems with weight, weight distribution, stability and brakes. In the beginning, the liter bikes actually lapped slower than AMA 250s, but the pace of learning accelerated. Steering heads were cut out and re-welded with more head angle. Chassis were stiffened with tubes, plate and gussets. Engines were moved forward so more power could be used without loss of turning ability from front-end lift. Swingarms were braced. To stop brake-disc warping, U.S. Kawasaki developed its own production technique.
    Early four-cylinder engines were fragile and tuning methods improvised. Some teams stacked on 12:1 compression, cranked in 45 degrees of ignition timing and hoped the things would last. Rod bearings tied up, and rods punched through cases. One morning as I walked through the Daytona garages in those early years, I counted five wrecked sets of Kawasaki cases and three Suzuki. Driven by necessity, teams worked through the night, and overtired mechanics made mistakes. Failure is a powerful teacher.
    Although the AMA had intended Superbike as a grass-roots class, success required serious engineering. Under the surface, a dynamic process was at work. To reach their potential, the four-cylinder teams had to transform their machines piece-by-piece from production motorcycles into purpose-built racers. Factories engineered stronger clutches, close-ratio gearboxes, improved connecting rods and more reliable valve springs. Roadracing required more than power from engines; it required a pulling range wide enough never to leave the rider stuck on a corner exit with his engine just below its torque threshold.

    As Superbikes came around on lap one of a race, first you would hear the strong, full sound of the three or four factory bikes tearing past. After an interval would come last year’s factory bikes, which had been sold to private teams. Then, after a longer period, would come what one factory team manager called “smoking junk”—bikes built by persons with more enthusiasm than engineering, using aftermarket drag-race parts intended to go only 1320 feet.
    Grass-roots or not, race fans loved the spectacle of roaring monster motorcycles, their riders sitting bolt upright, wobbling and weaving at high speed. This was heroic!
    Yoshimura switched from Kawasaki to Suzuki in 1978 and won Daytona four times in a row, plus the 1979 and 1980 Superbike titles. Kawasaki hired a two-stroke dirt-track specialist best known for his 490ccYamaha Singles: Rob Muzzy. At first, he was asked to do cylinder heads. They worked because Muzzy reasoned that traction on pavement at high lean angle was just as sensitive as dirt. That meant smooth power was best. Then, they asked him to do engines and finally, whole bikes.
    Honda joined the series, ordering titanium valves by the crate and sending out cylinder heads to all the top airflow wizards. Cams were ground in 5-degree increments of duration. Everything was tested and soon, dyno-uprooting power was the result.
    Eddie Lawson #21They called him “Steady Eddie” but what people were seeing were: a) Lawson’s totally championship-centered outlook, which did not insist upon winning every corner or even every race; and b) the effects of his preference for a stiff steering damper. Muzzy’s best engines made 150 hp at 10,250 rpm. Smooth power was key.
    Rob Muzzy’s holistic approach to racing helped Eddie Lawson become Superbike champion in 1981 and ’82, continuing with Wayne Rainey’s title in 1983. The modern era arrived that year, in the form of the AMA’s cutting Superbike displacement to 750cc and Honda’s decision to build the revolutionary liquid-cooled V-Four Interceptor. Honda had intended the Interceptor as a “homologation special”—a production bike with racing features, built only to legalize their use in a production-based class. But the market had changed. Word spread fast (“This thing handles great!”), and they flew out of showrooms. Suddenly, riders wanted these new full-capability motorcycles. These bikes didn’t have to be completely re-engineered to go racing, like the behemoths of the ’70s. All they needed were tires, a shock and detail changes to go production racing. The immediate result was the new so-called “Supersport” racing classes. In 1987, the FIM in Europe followed the U.S. lead, creating World Superbike.
    The chassis and suspension technologies that had been forced into being by Formula 750 and 500cc GP two-strokes of the 1970s were now incorporated into new liquid-cooled four-stroke production bikes. Superbikes have looked just like GP racers ever since.
