Dragtimes went out and dynoed a stock 2008 Dodge Viper ACR with only 1,350 miles on the clock and found out some impressive results. They managed to get the Viper ACR to lay down 546 horsepower and 510lb-ft of torque which means 642 horspower and 600lb-ft of torque after you factor in a 15% driveline loss. That's quite a bit of power that Dodge forgot to put out in its press material and enough to justify the unofficial Nürburgring lap as legit.

So, is the Viper ACR really faster than the current American horsepower powerhouse, the 2009 Corvette ZR1? We'll have to get these two out to a track to really know for sure (Hello? Chrysler? GM? Are you listening?). Until that happens, take a look at the video above and the dynograph below to see who really is the king of the American power wars.

The ASC built McLaren Diamondback Viper is now up for grabs on DodgeVipersForSale.com. Originally built for the 2006 Detroit Auto Show, the Diamondback Viper was a one-off concept based on the 2006 Dodge Viper SRT-10 Coupe that showcased lighter weight components and a McLaren tuned 8.0-liter V10 good for 615 horsepower. It was originally rumored that the Diamondback was the precursor to the 2008 model, but unfortunately it was shelved to live its life as a concept study only.

The Diamondback Viper featured custom carbon fiber body panels, a special stainless steel quad outlet exhaust, a custom carbon fiber racing stripe with "Mclaren Orange" and "Viper Blue" accents as well as a custom in-hood trumpeted air intake system with individual port throttles.

It's estimated that it cost ASC and Dodge $750,000 to build the one-off Diamondback Viper, but it can be yours for the much lower price of $295,000. This may seem expensive to you and me, but considering the collectability of concept cars, this is one's a steal.

Diamondback Viper Startup

Original ASC Press Release:

THIS IS NOT YOUR AVERAGE VIPER
ASC (American Specialty Cars) has a long history of developing vehicle prototypes with innovations designed to showcase the company’s expertise in vehicle design and performance materials. ASC showed its expertise at the 2006 North American International Auto Show by unveiling a supercar made even more super by the addition of a mostly carbon-fiber body. A ‘snake’ with an all-new skin, the ASC Viper Diamondback is super-light and super-fast. It’s fitting that ASC, which helped the Chrysler Group bring the new Dodge Viper SRT10 coupe to life, would, with the aid of McLaren Performance Technologies, show how the Viper coupe might be taken to an all-new level of ‘extreme’.

The 2006 615-horsepower Diamandback Viper features a carbon fiber roof, deck lid, rockers, fascia inserts and body trim. It also sports a massive OmniCarbon™ hood that shows off ten unique trumpeted air intakes, with individual port throttles peeking through. This is a McLaren Performance Technologies feature, reminiscent of McLaren Can-Am engines of the past.

The hood is comprised of compression-molded carbon fiber, both painted and woven. It’s displayed beautifully, with a broad, clearcoated racing stripe down the Arctic White painted expanse, subtly outlined by “Viper Blue” and “McLaren Orange” pinstripes. In all, ASC removed about 85 lbs. from the vehicle — the hood alone weighs about half of the standard production model. Taken together with the performance modifications by McLaren, the resulting power-to-weight ratio is estimated to yield an incredible 0-60 time — in just 3.5 seconds!

ASC MODIFICATIONS:

* Custom McLaren Performance Technologies engine tuning, resulting in 615 Horsepower

* Exterior racing-type kill switch

* Custom ASC OmniCarbon™ hood, with carbon-fiber roof, hatch, front chin spoiler, rear fascia, side rockers, deck spoiler, side venting gills and interior accents

* Custom in-hood tumpeted air intakes,
with individual port throttles

* 1.25" lowered suspension

* 4-point racing harness

* Custom stainless-steel, quad outlet exhaust

* Custom carbon-fiber racing stripe, with "McLaren Orange" and "Viper Blue" accents

* "Arctic Ice Pearl" paint

* Custom 3-piece forged and painted 19" aluminum wheels

The steel roof was custom designed and built as the car was originally a convertible model and other body modifications were made such as an extended and reshaped billet hood, grille and wheel wells, rolled rear pan, smoothed remote control doors, Mercedes E320 headlights and 18” front and 20” rear Boyd Wheels. Painted in PPG Deep Moss Green and Spanish Olive Green, this Viper powered ride is a great example of what can happen when an OEM and custom builders get together on a project.

Bristol Cars was initiated in 1945, when the Bristol Aeroplane Company began working with AFN Ltd, the makers of Frazer Nash cars, on a joint automotive manufacturing venture. Bristol Cars claims that it is currently the only wholly-British owned luxury car builder which makes us wonder if we’d really trust this car at 200+ mph speeds. This may possibly explain our inability to locate a driving video of the car, but we do have a neat image of all the aerodynamic design elements of the Fighter T below.

Decoma, a Tier 1 supplier, built the PT/10 atop a custom tube frame and it features a unique front grille, front fascia, taillights, a custom rear roll pan, rear bed, spoiler and side exhaust. Hiding behind the BBS wheels are a set of Wilwood brakes and a custom airlift suspension to make sure the PT/10 can handle as well as haul ass. The Decoma PT/10 won the award for “Best Overall Concept” at the 2001 SEMA show in Las Vegas. We want one. NOW.

In concept form the Challenger should get 600 horsepower and 560 lb-ft of torque out of the 8.4-liter V10. To keep the SRT10 on the road the concept was upgraded with new brakes and Bilstein shocks. To keep the SRT10 SEMA-worthy they added a carbon fiber hood to replace the stickers and some sportier seats. [Dodge via AutoWeek]

"As the Company evaluates strategic options to maximize core operations and leverage its assets, we have agreed to listen to these parties. We will do so keeping in mind the best interests of those who have shown tremendous support for the vehicle- including employees, suppliers, dealers and a worldwide group of loyal Viper owners and enthusiasts,” Nardelli continued, “Viper is an integral part of this Company's heritage. While this is a strategic review, our intent would be to offer strong operational and financial support during any potential transaction, in order to ensure a future for the Viper business and perpetuate the legacy of this great vehicle."

Jalopnik Snap Judgment: Why purchase Viper? Surely the current 2008 Dodge Viper SRT10 — a refresh of the 2003 model — is nearing the end of its useful life. Vehicles like the 2009 Nissan GT-R and 2009 Corvette ZR1 now offer considerably greater track performance combined with user friendliness and good road manners. All any potential buyer would receive would be a soon-to-be-outdated car, a brand with an image problem and the need to jump-start development on a replacement. If we were going to get into the supercar game, we’d start a fresh brand with a fresh product, free of the sins of the 1992 Dodge Viper RT/10 convertible its fathers. [Source: Automotive News, Sub.
