    GREATEST VELOCITY: A 617WHP ALFA ROMEO GTV


    Not every car we feature is obvious at first. Some make you work to find them, some come via a secondhand story, and some are simply tip-offs from trusted sources. But others – as was the case with Morten Ruud’s 1986 Alfa Romeo GTV – just creep up on you.
    It all came about after a conversation I had with Rod in the Speedhunters pits at Gatebil Rudskogen after a session shooting trackside. We were discussing what we had just witnessed and Rod asked if I had seen the “red Alfa Romeo”. Being the only Alfa out on the track there was no need for further description, but given that it appeared to be running front-mounted intercooler and rear-mounted radiator, we both knew we had to take a closer look.
    After a long walk we found the GTV pitted alongside all the other serious time attack machines, and quite rightfully so. Whoever had been driving the car was having a very good time and it appeared to be deceptively quick too. I say that because compared to a lot of the Gatebil machinery there was very little drama with the Alfa – just rapid progress and the ability to reappear at the same corner seemingly quicker than a lot of other cars in the group.
    Remember what I said about feature cars creeping up on you? Now that I sit back and take the time to reflect on Gatebil 2013, I realise we’ve seen this car before, both here on our #featurethis Instagram feed, and amongst last year’s Rudskogen coverage, albeit in a slightly different visual guise.
    Like fellow my Speedhunter Jonathan Moore,  I own an Alfa Romeo – not because I’m overly dedicated to the marque, or reverend Alfisti – but more so that I just like the Italian manufacturer’s cars. That said, the mere mention of ownership often leads to my sanity being questioned – after all, older Alfas aren’t exactly well known for their reliability or their repellence to rust. But what happens when you’ve modified virtually every component like RR Motor have on Morten’s GTV? Good things, that’s what.
    The gorgeous, angular coupe body style remains virtually untouched. Along with the change from white to red, the front end aero has been removed this year and without the large bumpers this model would have worn from the factory it reveals the purity of its original ’70s lines.
    The rear window air intakes are definite giveaway to where the radiator is mounted. Here you can see the pressurised fuel intake on the left, with the air extract point on the right. So if that’s going on at the back, what’s justifying it at the front?
    A longitudinally-mounted V6 as the car had fitted from the factory – but unlike the original 2.5-litre engine, this is a 3.2-litre V6 24V variant from an Alfa 147 GTA. Wearing standard heads, it would have been mounted transversely in the front-wheel drive 147, but RR Motor – which built and maintain the Alfa for Morten – has used a modified version of the GTV’s original sump to aid its switch to rear-wheel drive configuration.
    And then there the turbo – a rather large Comp Turbo CT3B 62-67 perched on a pair of custom exhaust manifolds that extend to the front of the engine bay. An Autronic SM4 engine management system makes sure everything works together as the guys have used a mix of parts ranging from VW coil packs to a strengthened bottom end to deal with the boost.
    The result is a genuine 617hp at the wheels and well over 700lbs/ft of torque to boot. If there’s a more powerful Alfa Romeo V6 engine derivative out there, we certainly haven’t heard of it!
    That sort of output goes some way in explaining why it’s so quick on the track, and why, on very rare occasions, it breaks traction too when provoked too much. I say very rarely because unlike most of the high horsepower, rear-wheel drive cars you encounter at Gatebil, the Alfa was built for grip. Morten had the coupe built up four years ago for Corsa Italiana – a Norwegian national racing series  for all Italian cars over 15 years old, which he still competes in now.
    During its racing life there has been constant development of the chassis and today the running gear features an incredible hybrid of parts.
    Big brakes are a given, although the Alcon upgrade is all about quality not quantity. That said, the four-piston callipers fitted with Ferodo competition-spec pads do a more than adequate job given the size and weight of car.
    If you’ve driven a car on slicks, you’ll know firsthand just how much difference this one modification can make. It doesn’t take a genius to realise the monumental increase in contact patch and what that means, so when you see a set fitted to an otherwise moderately understated project, a statement of intent is made.
    Big changes have been made in the suspension too – something evident when the GTV is at speed. This, for example, is a 180-degree left hander taken at around 80mph. Intrax adjustable coilovers are used each corner with the standard rear De Dion set-up retained, but modified for increased camber. The front strut set up is Volvo v70/S80 design with custom made upper and lower A arms. I guess something had to be Volvo on this build given it’s Norwegian origins.
    When people are wary of a manufacturer it’s generally because of something in there they don’t really understand. Take Mazda’s rotary engine for example, or in this case Alfa Romeo’s choice to mount the gearbox in the rear with the differential. This makes total sense to me though – there’s the weight distribution aspect for starters, and the ability to have the engine mounted further back in the chassis without having to worry about the impact a conventional rear-wheel drive might have on cabin space. Here you can see the simple shifter that allows you to bang through the straight cut Drenth sequential gears in the Sellholm-sourced gearbox.
    The rest of the interior is business-like. Protection is paramount and the cage adds some much needed rigidity to the aging shell.
    When it comes to owning an older Alfa Romeo you definitely need a sense of humour…
    But the interior features some serious hardware too – like the extended, quick-release steering wheel boss. Look at most race cars and you’ll see the distance between the driver and the wheel is often closer than you’d expect if you’ve not driven something similar. This is to give you increased leverage with bent arms and the ability to pour lock on without shifting position. The driver is aided here by the a compact electric power steering unit sourced from an Opel Corsa.
    Also in clear reach is the ignition switch and the simple LCD gear indicator – somewhat of a necessity with sequential gearbox and especially so when things get busy in the cabin.
    I still can’t decide whether the Alfa is understated or not. It’s hard to tell given when you’re wrapped up in the Gatebil experience, but what about out in the big, bad world? The simple monotone paint scheme and subtle body modifications such as the raised rear window are just that, subtle.
    But flared front fenders from Alfapanels in the UK and slicks aren’t exactly common though.
    This is a car where you have to look deeper to really get a handle on the details. The simple floor-mounted Tilton pedal box is actually quite delicate looking, but well balanced – just like the rest of the Alfa.
    With the bonnet off it’s quite obviously something special. The engine choice is clever and to me it almost feels like a natural progression from the original rather than a complete departure in the wanton pursuit of power. That’s something we’ve seen a lot of in our Scandinavian theme this month.
    Like many of builds we’ve covered this month, everything serves a purpose. So it would seem that’s how this project fits in to our theme, serving to show us whether it’s an LS-engined Volvo estate , a Toyota-engined BMW  or a discreet mid-’80s Alfa Romeo GTV, the Scandinavians have a way of extracting fun and performance like you’ll rarely see elsewhere. Their builds are often outrageous sounding, but in the metal actually quite inoffensive and humble. But always effective.
    So as one of the last feature cars we’ll put up from our month-long Scandinavian celebration I’d like to look at what impression we’ve given you. Is Scandinavia all about engine swaps, mad power and home brew ingenuity? Yes it is, but there’s more. And as this GTV proves, sometimes you just have to take the time to look a little closer…

    HARLEY XL883R BY SHAW SPEED & CUSTOM


    XL883R
    Like Gulf Oil, Martini is a brand inextricably associated with speed. The blue and red stripes are one of the most distinctive liveries in motorsport, and forever associated with the Martini Racing Porsches from the 1970s.
    Martini hits its 150th anniversary in 2013, and the English shop Shaw Speed & Custom has joined the celebrations by creating a pair of hot-rodded Harley Sportster XL883Rs—one in white, and one in silver, as shown here.
    XL883R
    Each bike has a rebuilt motor with a tuned Screamin’ Eagle 1200 conversion, race-spec heads and pistons, and a custom-fabbed exhaust system. The forks have been fitted with Öhlins internals and finished in gold to match the rear shocks.
    XL883R
    A lean Roland Sands Design gas tank and RSD bars add a little attitude, and the brake rotors have been replaced with larger versions fore and aft, beefing up stopping power.
    XL883R
    The original fender rails have gone, with the frames modified to accept kicked-up rear fenders. The wheels are also custom built, with modified Dyna rims taking 180mm tires at the rear.
    XL883R
    Head over to the Shaw Speed & Custom site for more images of both Martini bikes, and a thorough rundown on the technical details.

    BEAUTIFUL CAFE RACER RENDERS BY EL OSARIO MOTOCICLETAS


    These truly are unreal motorcycles, if like me you thought these where real bikes then think again. The beautiful cafe racer renders have been done by Roman Sanz at El Osario Motocicletas. I was totally fooled by the quality of these renders and you can see why. What a great collection of custom designed motorcycles, I think we have a bike building legend in the making here. They are all great but I really like the land speed Harley Davidson, beautiful raw metal with a really cool teal stripe… looks amazing and to think these have all been done on a computer.
    His tumblr site is brilliant and full of many other designs well worth checking out, loads of really cool ideas to get your teeth into and get inspired to start building. I think these are such a cool thing, ideas that you would normally not think about when building a bike because it might seem impossible or too much like hard work. But when digitally rendering you only limitation is your imagination and of course your skills in photoshop.
    I look forward to these beautiful cafe racer renders becoming real bikes and I’m sure we have a master on our hands. Please take the time to check out his website. Some really cool bikes here.

    SHELBY WOULD HAVE APPROVED: THE V12 COBRA


    Big engine, little car. It’s an age-old recipe that has been putting big grins on the faces of car guys the world over ever since modifying began. Back in the ’60s Carroll Shelby did just this with the AC Cobra – shoehorning big Ford V8 motors into the light UK-built chassis to create one of the most legendary cars of all times. Magnus Jinstrand has always wanted to create his very own Cobra and when it all started to materialize for him he decided to take things a little further than originally planned…
    … further evolving the original notion that defined Shelby’s cars and turning it into something all his own.
    There is absolutely nothing subtle about this car, from the moment you lay eyes on it, it shouts out at you with aggression. From the rather large supercharger rearing its head out of the hood…
    … to the copious use of carbon fiber that makes up its custom aerodynamic package.
    There’s no hiding the fact that this is a superbly executed modern-day take on the original, right down to the 18-inch and slick-shod Rondell wheels. A Brembo braking package borrowed from a Lancer Evolution VIII hints that there must be a lot of performance hiding within…
    … but nothing can quite prepare you for that initial visual impact the removal of the engine cover creates. Magnus’s initial plan was to fit a Mercedes-Benz V8 engine into the Autofab chassis that lies beneath the Dax-built exterior, but when the guy supplying him the engine gave him choice to go for a V12…
    … well, let’s just say that he just couldn’t pass it up. The 6.0-liter V12 is a twin-spark (yes that means 24 spark plugs!) 36-valve (two valve per exhaust side) beast engineered to deliver a silky smooth and effortless surge of power. In its stock 2001 Mercedes-Benz CL600 configuration it developed 362hp and 530Nm (39 lb/ft)…
    … so to make things a little more interesting Mangus added a Lyshom 3500 twin-screw supercharger, modifying it to accept a custom twin-throttle set-up. Lots of custom work was required to not only fabricate the two intake plenums, but also to plumb everything into place in a visually-gratifying fashion.
    From the color-matched piping to the sheer size of the powerplant, everything is meticulously executed.
    Custom stainless steel manifolds snake down…
    … on each side of the Cobra…
    … and connect onto a pair of big bore side pipes that flank the bodywork, dumping gasses before the rear fenders.
    Underneath it all Magnus has adapted front and rear suspension from a Corvette C4 and uprated it with Öhlins adjustable dampers. Their remote reservoirs have been relocated within easy reach for fumble-free access to the adjustment knobs.
    In its current configuration the supercharged V12 pushes 492hp to the wheels (around 600hp at the crank), all thanks to a very gentle 0.35bar (5psi) of boost. Drive is sent to the rear end via a Getrag six-speed transmission mated to a Helix twin-plate clutch and a custom propeller shaft.
    Avon slicks measuring 245/645R18 at the front and a massive 305/680R18 at the rear offer plenty of grip through the corners…
    … while Micke Svensson – who is responsible for all the carbon fiber on the car – designed and created the rear diffuser…
    … which along with the adjustable Carrera Cup inspired rear wing helps keep that rear end planted. The whole exterior has been finished off in a flat bronze hue, custom mixed and sprayed by one of Magnus’s friends.
    If you’re wondering why the trunk lid has been swiss-cheesed lifting the lid reveals why. On top of the front-mounted copper radiator a second one has been fitted in the rear for extra cooling.
    Despite the car being solely for track racing and events like Gatebil…
    … everything has been finished off beautifully. this being especially true with the interior where Auto Meter gauges…
    … have been centrally mounted in the carbon fiber dash panel.
    It may be a tried and proven formula, but big engines in small cars just never seem to get old. Magnus’s undeniably-Scandinavian approach to his project has turned his dream of owning a Cobra into something even he never initially fathomed. Something tells me that Carroll Shelby definitely would have approved!
