    Hennessey Challenger SRT600 Turbo Runs Quarter-Mile In 11.9 Seconds, 121 MPH

    The folks at Hennessey have finally revealed the quarter-mile time on their mad-crazy Challenger SRT600 — and it's a pretty-stellar-by-Mopar-standards 11.9 seconds, with a top speed of 121 MPH. Although we already knew from our exclusive visit to the Hennessey compound, the Hennessey Challenger SRT600 churns outs 536 HP and 582 lb-ft of torque at the wheels, we'd been waiting to see just how fast it would be. Well, now we know, and we've got video from the Texas-based tuners to prove it.

    1,000 HP Ford GT: In Case The ZR1 Seems A Little Underpowered

    It now takes two hands to count the number of production supercars making over 600 HP, which means it’ll take at least 400 more HP to guarantee permanent one-upmanship against the Joneses. That's where this eBay find comes in. Sure, the starting price of $229,500 is a bit steep for a Ford GT, but you’ll be bidding on a car equipped with the best interior of any vehicle yet this decade. Oh, and there’s the Hennessey twin-turbo conversion that nets “1000+” HP and 865 lb-ft of twist. All that power is good for a 235.4 MPH top speed — but probably not a 7:26.4 ‘Ring lap.

    Hennessey Performance: Walking The Line Between Sanity And Audacity

    When one of the ways for employees to get out of the Hennessey Performance compound in Sealy, Texas is by driving down a drag strip, you begin to see why people perceive them as mad-for-power. However, after spending a day with the people at Hennessey Performance, I can say they're just like anyone else. Anyone else knee-deep in enthusiast's money and supercars.

    Hennessey Challenger SRT600, Exclusive First Pictures And Power Numbers

    Wert may have gotten a thrill from that stock 2008 Dodge Challenger SRT8, but some owners are going to demand more power. That's where the Hennessey Challenger SRT600 comes into the picture. Last week we showed you first pictures of it undergoing the transformation into a turbocharged monster and now we've got pictures straight from Hennessey HQ of the car in final trim. We've also got dyno numbers from yesterday's testing to answer the obvious question: How much power is going to those fat rear wheels? Read on.

    2009 Hennessey Dodge Challenger SRT600 Turbo, Exclusive First Look

    The mad tuners at Hennessey have turned their turbocharging tech toward the new Challenger SRT8, creating this just-about-built beauty of a beast — the Challenger SRT600. Having quickly snapped up one of the few SRT8s out there (on eBay, for quite a markup), the crew was hard at work this week readying the first SRT600, seen here. There are no final power numbers yet, but the addition of turbos, high-flow cylinder heads and other speed bits have resulted in output above 600 HP and 600 lb-ft of torque in other vehicles featuring the 6.1 Hemi under the hood — like the SRT600 Grand Cherokee. Expected performance numbers below the jump.

    The 2009 Corvette ZR1 is Coming! So Sayeth Hennessey, Reveals 678 HP Venom 650R

    Somehow we think maybe the 2009 Corvette ZR1 pre-Detroit Auto Show embargo will be lifting sometime very soon. It's the only explanation we can come up with for why Nissan felt compelled to have an embargo on the 2009 GTR's Z06-beating Edmunds Inside Line 0-60 test lift late last night. OK, maybe that was just a freak scheduling thing — but then, like a bolt out of the blue devil, we received a press release just past midnight from Hennessey Performance Engineering calling out the Lutzian devil with the blue highlighted engine. Apparently they weren't quite done with the 2008 Viper SRT10. The boys at Hennessey came up with an additional 78 horsepower to add atop the straight-from-the-shelf 600 found in the fang-toothed serpent, bringing the total horses up to a staggering 678 and a 0-60 time to match that of the 3.3-second GT-R. It's called the 2008 Hennessey Venom 650R, and oh, how they rushed this one to bed — someone check out the gaping hole below the jump in the press release for "fill in original Viper model name here". Yes, somehow methinks these won't be the only high horsepower numbers we'll be comparing by the time we hit the hay tonight.

    Hennessey reveals the Venom GT's rear end

    Last month we brought you the first sketch of Hennessey's Venom GT. Now, the company have revealed what it will look like from behind, the view that will be most common to Veyron drivers as this car makes an identical 1000+ bhp, but will weigh 1,500 lbs less. Hennessey are looking to build 2 concept versions of the Venom GT in 2009, if those generate enough interest, they might make it.

    Hennessey Reveals 1000 HP Venom GT Concept Car

    Looks like Hennessey Performance Engineering — the tuners of all things Mopar and SRT — are not going to sit back and kick up their heels with their twin-turboed Viper — the Venom 1000 SRT. No, they've just revealed their suspected new concept super car, the Venom GT — and yes, it's mid-engined. The Steve Everitt-penned light wight chassis Venom GT will incorporate Hennessey's massive Venom 1000 Twin Turbo Viper V10 powerplant and all thousand of it's snake-spookin' horses and still tip the scales at just under 2,700 lbs. That gives the GT an astonishing 2.7 lbs per horse — and a purported 0 to 62 mph time of less than 2.5 sec. Even more important however would be the 0 to 186 mph time — which Hennessey's claiming is a quick-as-a-cobra-strike 14 seconds. But company CEO John Hennessey's claiming this car isn't a "Veyron slayer" — oh, no — he already lays claim to that title with his Venom 1000 Twin Turbo SRT. No, according to Hennessey, this isn't a car for a Veyron driver — no, it's much more of an "engaging" drive than the Bugatti uber-car because of the 1500 lb weight differential. We'd have to agree — this car looks insane. We'll take two please, one for us and one for our tame race driver. Full press release after the jump. More »

    Tuner Hoonage: Hennessey Twin-Turbo Viper in 220 mph Run

    What can two gargantuan turbos do for a Dodge Viper in the zero-to-220 mph department? No need to wonder. Hennessey Performance offers this clip of the company's Viper Competition Coupe tearing off a strip of Texas's space-time continuum in 24 seconds. Excuse the hyperbole, but listening to the Viper's turbo whine-wastegate sonata has been known to cause gross inelegance. More »

    C/D Drinks Up All the Hennessey John's Got On His Shelf: Grand Cherokee SRT600

    The Grand Cherokee SRT8 is already somewhat of a sleeper. Certainly, those in the know recognize its prodigious performance. But what happens when one sends one's Jeep off to Hennessey for a 27k tune-up? Epic soccer-mom-look hoonage available at a stab of the loud pedal to the tune of 620hp and 650 turbocharged torques. Car and Driver recently took one out for a spin, and the boys from Ann Arbor point out that it's quicker than practically anything one can buy for the price, hammering not only its ber-ute bretheren, but such warp-velocity steeds as the Lamborghini Gallardo; it's only off the much-lighter Z06's quarter-mile time by half a second. What's more, optioned judiciously, the beastie comes in under 70 large. More »
