Click above to watch video after the jump

Back in January, we showed you an early rendering of the Hennessey HPE700, a car we called the bastard love child of a Camaro SS and Corvette ZR1. Development of the "ZR1 and then some"-powered Camaro is well underway, and John Hennessey of Hennessey Performance Engineering just sent us this video of the HPE700 powertrain being manhandled by the recently retired John Heinricy on a track in Texas. For now, the 705-horsepower LS9 engine tuned by HPE is living in its native home beneath the hood of a yellow ZR1. In the hands of Heinricy, it propels he and the car up to 145 mph on one of the back straights at MSR Houston. The engine sound is sonorous and quite unlike what we're used to hearing from a Corvette, which means it should sound downright alien in the Camaro. Follow the jump to watch the video and hear what we mean.

      Guys look at the video again and concentrate on the the track, there is another car that can't be caught up to :O
        • 5 Years Ago
        The only other cars on the track was a 996 GT3 Cup car, a couple of older Panoz racecars, a radical and a couple of street cars.

        If you pause it, save the screen shot into paint, zoom in real close after converting it to a jpeg (and a little help from Photo Shop) you'll find that the little white car is really a Fiat 500 Abarth...
        Amazing, those Europeans can always come up with something running 4 cyl that still kicks NA V-8 ass...sheesh when will we ever win!! Drives me nuts.

      My god that thing sounds good. Why the hell can't it sound that good from the factory?!

      STFU about Hennessey posts are beginning in 3.... 2... 1...
      • 5 Years Ago
      Let's how long before the obligatory Hennessey is crook post shows up.

      We're going to need a clean up, on aisle three...
        • 5 Years Ago
        Please stop acting like you're not impressed
        • 5 Years Ago
        I'm also posed in an awkward stance...
        • 5 Years Ago
        Don't tell your friends or I'll say you're a slut.

      That Camaro could be Bumblebee's evil twin brother. I'm remembering the Knight Rider episode with KITT and KARR...
      • 5 Years Ago
      It sounds great.

      I have an LS2 powered C6 with Kooks long tube headers and Corsa Sports exhaust. Other than the fact that the LS9 powered car in the video gets through the rev range a lot faster, it surprisingly does not sound much different from my car.

      I wonder if the author of this post has ever ridden/driven in an aftermarket full-exhaust C6. If not, I highly recommend it! ;-)
      • 5 Years Ago
      Yep...that sound reminds me of why when I dream up cars & engine swaps in my head there is always a high revving V8 involved...
      • 5 Years Ago
      why not get it over with and do what I know alot of people want.. drop the ZR1 engine into the pontiac solstice... make a rwd cobalt 'ss' with this engine too.. heck why not drop it into the engine bay of the silverado too? might be fun, afterall dodge did that with the viper v10 back in the mid 90s with the Ram vts, and the Ram srt10, and ford with the lightning f150. plus you gotta figure with so few rwd cars still being produced (hopefully they won't be axed too soon) the solstice would be another interesting platform for this engine. even as a one off concept. one scary @$$ ride too but fun. and no not referring to Hennessey, just the concept of the powerplant's uses in the GM/Chevy pipeline of rwd cars and trucks currently around.

      when Hennessey said 638 hp not enough for ZR1 ... and made ZR700 ... I liked corvette more than before ...
      So I think this is not hard to make a powerful comaro .... and other mobile

      adn .. ya .. this sound is impressive
      • 5 Years Ago
      The fact he goes 'round in two gears is impressive.
      • 5 Years Ago
      Hennessey is a crook?
        • 5 Years Ago
        He was/is known to use his client's car's parts for his own projects.
        • 5 Years Ago
        yup, I heard he hosed a bunch of Viper people. Now he's gonna prey on ZR1 folks
