Video: Hennessey twin-turbo Camaro boasts 847 rear wheel horsepower!

Is too much horsepower a bad thing? Is there such a thing as too much power? We raise these eternal questions thanks to the 2010 Hennessey HPE1000 Twin-Turbo Camaro and it's insane power rating of 847hp and 801 lb-ft of torque - at the rear wheels.

If that is a tad too crazy for you, consider the tame HPE800, which produces a mild 815 horsepower and 788 pound-feet of torque at the motor. Surely that will be a more reasonable grocery getter.

Check out the video below to see the HPE1000 laying down the goods on a dyno. We're surprised the sheer torque didn't alter the rotation of the earth, or at least Hennessey's shop.

Video: Hennessey's HPE700 Camaro on the track

Hennessey has managed to shoehorn a ZR1's LS9 under the hood of a new Camaro, and tuned it to put out 705 horsepower. Not only did they add some serious power, they added some serious suspension parts to make it handle as well as it goes in a straight line.

Of course they wanted to make sure that it lives up to all that promise, so they set out to wring the car out at the track. Specifically, MSR Houston. Check out the video to hear all the sweet sounds of the LS9, and watch the car pull 1g on some turns.

SEMA 2009: Hennessey HPE700 Camaro

We've had more updates, videos, and teaser pics of the Hennessey HPE700 Camaro than perhaps any car in the last year. News bit after news bit has surfaced over and over again, building hype around the car that becomes the first Camaro to sport the mighty Corvette ZR-1's motor.

And that motor is, of course, blessed with some power adders to boost horsepower to 725 and torque to 741 lb-ft. That's good enough for a claimed 3.5 second run to 60 mph and a quarter mile time of 11.3 seconds at 126 mph. And if you're the sort of person who likes to carve corners as well as go fast in a straight line, the HPE700 also reportedly pulls 1.01g's on the skidpad.

If you are a fan of the HPE700 (and who isn't?), be prepared to pay the price and do it quickly. Of the 24 that are going to be built, only 5 are not spoken for at the $119,500 price tag.

Video: Hennessey HPE700's LS9 is running

We recently brought you some pictures proving that the Corvette ZR1's LS9 fit well in the 2010 Camaro, specifically in Hennessey's HPE700. Now they have the beast up and running, and the sound is truly something to behold. Keep in mind the car is running with open headers, but it should still sound nasty with a full exhaust.
