Click above for a high-res photo of the Hennessey Corvette ZR700

Not satisfied with the 638 horsepower on tap in your Chevrolet Corvette ZR1? Hennessey Performance has the solution. They've come up with a tuning package that includes a smaller supercharger pulley that increases boost from 11 to 14 psi, an upgraded intercooler, K&N intake, stainless steel headers, high-flow catalytic converters, and a reprogrammed engine management system that pushes output past the 700-horsepower mark. If that still doesn't meet your needs, Hennessey can keep the upgrades coming with high-flow cylinder heads and a more aggressive camshaft that puts the ZR1 at 755 hp. Hennessey's website says that 1000 hp is attainable, and we're guessing it involves a pair of turbochargers. Follow the jump to watch a video of the Hennessey ZR700 knock out an 11.03 second quarter-mile with relative ease.

      exactly, the green light is irrelevant in this case, he couldve been in motion any time he wanted.

      Holy turd that is a fast car.

      Is Bugatti to blame for this "1000hp is the new supercar standard" crazyness? I think so.

      Not that I object to it, but it is a pretty insane amount of power that really shouldn't be dropped in the hands of people who aren't trained drivers.

        Supras and Skylines were pushing over 1000hp way before the Veyron. Must longer. Supras and skylines were some of the first to not just reach that mark but brake it. There's a drag supra that is pushing out 1500hp and he drive it home.

        JDMlover:

        These 1500hp Skylines and Supra's were stock, of course.

        Thought so.

        If you're talking modified, sky's the limit. 1000hp+ was done by street driven muscle cars decades ago.

        As IF those two cars were "the first"...HAHAHAHA

      It bothers me that this thief gets so much mainstream media attention. He has been called out countless times for his shady business practices, yet he is still respected by the automotive press. I don't get it.
        • 5 Years Ago
        Indeed. He comes across like someone I would NOT want to leave my car with. I hate shady mechanics.
        • 5 Years Ago
        Corvette and viper owners getting taken for 100s of thousands of dollars...boohoo.

        They had a guy in the thread who bought a brand new GTS, then handed $142K to Hennesey. Um ok...
        • 5 Years Ago
        Mat, I upranked you because I comepletely agree.

        However, you have to admit that the cars he DOES deliver are orgasmically powerful, even if they only go to the press.

        I can only speculate that that's the reason the mainstream media continues to go ga-ga for him.
        • 5 Years Ago
        I for one don't get why Autoblog keeps posting stuff about Hennessey when there have been so many calls from the reader community to stop.

        It really speaks poorly of this blog that it still continues to post about him when there is now so much established history about how he does business.

        I keep wondering the same and what I keep asking is why this man is still in business.

        +6

        Sister site Engadget had the cajones to blackball Monster Cable, why doesn't Autoblog do the same with this scammer?
      • 5 Years Ago
      oh lawdy have mercy
        • 5 Years Ago
        HEAVEN ON WHEELS !!!!!!!!!!!!!!!!
      • 5 Years Ago
      Why give this guy free publicity. He’s a thief!
      • 5 Years Ago
      I used to be in awww with the Hennessey Vipers.. and hoped that one day I would own one. (I've owned many sports cars)

      But after reading all the lawsuits Hennessey has been through..and how he hasn't returned cars that people have hired and PREPAID for him to do work.. I'm really let down. This guy could have had a blossoming business, but instead has been a trainwreck.

      He reminds me a lot of my uncle.. always has a scam.. and if he just had the right direction could have run a fortune 500 company!

      • 5 Years Ago
      Why can't more cars be flatt black...
      • 5 Years Ago
      I would love to see a Hennessey shootout between a Hennessey 1000hp Viper, 1000hp Ford GT, and 1000hp ZR1. A trio of American cars with 4-figure horsepower, what more could you ask for?
      • 5 Years Ago
      sam is correct.

      You can launch as soon as the light turns green, and run the 1/4 mile in 13.0 seconds, or you can wait an hour, then launch, and that 13.0 seconds will still be 13.0 seconds.

      The only instance where the green light matters is head to head racing, like NHRA.
      • 5 Years Ago
      The clock does not start until the car crosses the timing light. The green light does NOT start the clock!
      • 5 Years Ago
      I would think another 60 hp could know off more than 2 tenths. A very skilled driver that knows the car can get a stock ZR1 in the high 10's in perfect conditions.

      Judging by the video it's pretty cold out, so conditions obviously aren't optimal. This thing is definitely capable of mid 10's.
        • 5 Years Ago
        Hell, a stock Z06 has been known to break into high 10's. The ZR-1 should be able to shave a few tenths off of that.
      • 5 Years Ago
      OK, I don't know much about drag racing, so this is an honest question:

      Does the clock start only after the car leaves the line? In the video, there's at least a 1 second delay after the tree's green light comes on.

      Just wondering...
        • 5 Years Ago
        Dunc and Caddy-V what are you guys talking about? Have you ever been drag racing? Your E.T.(in this case the 11.03) has nothing to do with how long you sit at the light. The time from when the light turns green and when you move is your R.T. or reaction time. You dont subtract a second from anything. It doesnt matter how long he sat there after the light turned green, he would have still run an 11.03. Reaction time only matters if you are trying to be the first one to the end of the 1/4 mile.
        • 5 Years Ago
        Yes, this is why you can have low ET and still lose the race.
        • 5 Years Ago
        Nope, that's just driver error. When the light turns green, the clock starts. So when someone talks about reaction time, that's the time between when the driver gets the green light, and when he or she gets the car moving.
        • 5 Years Ago
        I caught that too. The clock starts the instant the green light is lit. Shave a second.
        • 5 Years Ago
        Yes, this is why you can have low ET and still loose the race.
