A few days ago Underground Racing unveiled their twin-turbo Ferrari 458 with 700 rwhp output. It was superb. Now Heffner Performance has come up with a similar package, which on pump gas generates 820 HP / 700 whp. Both of these kits are the tuners first crack at the 458. More powerful programs are already in the works.

Check out Heffner’s 458 after the jump.

American tuner Heffner Performance has released yet another overpowered product, this time based on the Lamborghini Gallardo. They call it the 560-TT which refers to the twin-turbochargers they have put on the car’s V10 engine. So it churns out 850 hp on normal fuel and a whooping 1000 hp if  you feed it with 100 octane gasoline. The torque power is also around 1000 nm.

So you expect it to blow up your mind when it comes to performance, and it does! 0 to 100 km/h takes only 2.8 seconds and it has a top speed of over 330 km/h.

Apart from the horrible blue paintjob, the exterior remains mostly standard. Only a carbon fiber rear spoiler is added to make more downforce and push the back of the car down at high speed for the sake of more grip.

Heffner has not released pricing for this package yet.

American tuner Heffner Performance has been working on their twin-turbo package for the V8-powered Audi R8 and apparently they are in final stages of development. Here’s some new pictures and a video of the car. Don’t expect a massive body kit or anything though, as it looks like a standard R8. But the real beauty of this cars lied beneath the hood! Heffner has done a neat job here.

Those turbo airbox casings and marvelous exhausts are actually so mechanically beautiful that you if you buy one of these, you might want to remove the rear bumper and the hood to show them off! Of course this system works as good as it looks. The standard 420 hp is bumped to 543 hp on the rear wheels, which is even more than the V10-powered R8. But that’s just the beginning, feed this engine with 100 octane gasoline and it has the potential to churns out as much 723 hp!

But the coolest thing about this car is the fact that it looks like a normal R8. It fools everyone, until you put your foot on the throttle, then all hell breaks loose!!!

Heffner Performance is best known for their tuning packages for Lamborghini models. Now though apparently they are trying their hands on the supercar of the the parent company, the Audi R8. What they have in mind for it is very cool! They are going to put two big turbochargers on it which is said to give way more than 600hp on 100 octane fuel. Here’s a clip of the car in talk in development, as it’s doing the dyno test. At this stage it has 536 hp! More details will be released when the car is finished.

Heffener Performance, the exotic tuner, teamed up with the fashion artist Camilo Pardo, chief designer of Ford GT and made a very special one. While Heffner was fiddling with performance, Pardo added some nice design enhancement to the car, and the result is really cool. Heffner’s twin turbo V8 checks out more than 900 horsepower.

Ford GT has received the Heffner Twin Turbo system which is already proven on the road as well as the racetrack. Even as the vehicle preserves all its production handling, performance was demonstrated to be alien at the opening Car and Driver 0-200-0 shootout. Producing over 900hp, the system has been shown to attaine 200 mph from standstill in less than 19 seconds, logging in excess of 150 mph in the quarter mile. One of the few outsiders to ever see the interior of the Ford testing grounds in Dearborn, MI, the Heffner Twin Turbo was an immediate success with many of the team members who designed the initial supercar. In the CAmilo Edition, the fundamentals have stayed the same, but this special edition highlights an all-new, Camilo-developed billet aluminum intake.

The car highlights a number of main artistic enhancements the developer had sought to include from the factory including

• Exclusive Roundel and Number Graphics
• Heritage racing-motivated paint finish
• Flat black BBS wheels
• Classic Design Concepts’ treatment of the rear bumper in the style of a concept car
• Black-lip mirrors
• Seat grommets made of aluminum
• Shift ball made of chrome
• Lasercut door trim rings provided by OEM supplier Quality Metalcraft
• Broad-shaft shifter
• Wrinkle black valve covers
• Flat black gas cap and door latches
• T&A Shocks height reduction
• Shiny exhaust tips
• Brembo caliper graphics

These embody subtle revisions that Camilo Pardo believed was sufficient to convert the car into a more ultramodern, race-motivated appearance. By any means, the aesthetic skills of Camilo have elevated this vehicle to a whole new level. It is an arresting car on the street, maintaining the elegance of the GT but with an intensity that screams out for swiftness. The Camilo Edition Heffner Performance TT GT also comes with a Setrab transmission cooler for extra performance improvement.
