The LP670-4 SV is the swans song of the Lamborghini Murcielago range, a snorting, snarling supercar with hypercar ambitions. Yet no SV owner can hold his head up high knowing that it only produces 670 hp, while the car that replaced it, the Aventador, makes 700 hp.

As the story goes, David Wiggs, the friend of supercar social media personality Robert Himler, recently bought a Murcielago LP670-4 SV. And the first thing he did with it was to take it to a dyno. In it's all-wheel drive configura...[...]

The Ferrari 458 Italia has recently been targeted by British tuner Kahn, which is now offering us the result of its interaction with the Italian supercar.

The Ferrari FF is am incredibly impressive machine, as it mixes a multitude of assets with the Prancing Horse' spirit. However, there will always be some who want more, and if that includes seriously upping the ante on the hp front and making the vehicle much greener at the same time, we want to know about it.

Norwegian aftermarket developer Customised.no has developed a bio-ethanol E85 conversion for the Ferrari FF, which takes the car's V12 unit from the stock 660 hp to 887 hp, while seriou... [...]

While Ford has been tempting everyone with the idea of offering a successor for their famous GT supercar, tuners are hard at work with the current model they do have on hand. The GT Guy, a garage that tunes Ford GT models exclusively has announced their latest project - the Ford GT "Merkury 4" - developed in cooperation with Camilo Pardo ? the designer of the original GT.

The Merkury 4 is based on a solid red Ford GT that features a Mirrachrome abstract custom paint job with a florescent orange center stripe separated with a satin black pinstripe. The car was equipped with HRE center-bolt rims with 275/30ZR19 front and 345/30ZR20 rear Michelin tires. And because one of the most impressive features of the GT can be found under the hood, the tuner has equipped the car’s 5.4 L supercharged modular V8 with a second generation Whipple supercharger and a GTG cold air intake kit that increased the engine’s output to an amazing 725 rwhp at 19lbs of boost on 91 octane fuel.[...]

It’s been a while since we last reported on a Maserati GranTurismo S, but this latest version has certainly got our attention. This is no ordinary GranTurismo S; this model has been given some expert attention by Diamond Black Exteriors - aka DBX - to spice it up.

In actuality, all the tuner really did was come up with a phenomenal exterior package, but that was enough to transform the Maserati from sexy to sexy as hell. The exterior package’s most recognizable feature is a very cool satin orange foil wrap with carbon fiber displayed on the hood, mirrors, door handles, and grille. The roof was then wrapped in matte black with an Orange Maserati Crown decal, while the headlights were tinted in iron and the taillights in medium smoke. The GranTurismo S now sits on a new set of 22" Foose Wheels with an orange and black crown on the center cups and color-matched satin orange brake calipers.[...]

Prova, one of the more notable Subaru tuners in the Land of the Rising Sun, teamed up with the Japanese automaker to display a bespoke edition of the new BRZ sports coupe at this past weekend's 2012 Tokyo Auto Salon.

The Chevrolet Corvette ZR1 is considered the most powerful Corvette in history, boasting of an LS9 6.2-liter V8 engine that produces a supercar-worthy 638 horsepower and 604 lb/ft of torque output. German tuning firm, TIKT, thinks that those eye-popping numbers aren’t good enough, and just like any self-respecting tuning house on the planet, they’ve set out to add even more ponies to the mighty American sportscar.

To give the Corvette ZR1 some extra juice, TIKIT unloaded a number of upgrades on the sportscar, including modified cylinder heads, new camshafts, more powerful valve springs, modified compressor ratios, a larger throttle valve, and a custom exhaust system. In addition to all of these, TIKT also improved the Corvette ZR1’s cooling system, making it even more efficient than before.[...]

We can hardly see this video making it on Discovery channel, but our science-minded readers will surely appreciate the following clip that shows what a twin-turbocharged Lamborghini Gallardo tuned by Underground Racing with some 1,250 wheel-horsepower can do to a pair of silicone implants when it's accelerating full force.

 

You can take notes of the effects while watching the video that follows after the break.[...]
