Hennessey unveils 705 HP Corvette ZR700 upgrade

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.

I'm not an enviro-nut, but this is ridiculous.

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.

Indeed. He comes across like someone I would NOT want to leave my car with. I hate shady mechanics.

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

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.

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.

Sister site Engadget had the cajones to blackball Monster Cable, why doesn't Autoblog do the same with this scammer?

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...

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

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.

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.
Egon 11:33AM (1/29/2009)
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...

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.
caddy-v 11:44AM (1/29/2009)
I caught that too. The clock starts the instant the green light is lit. Shave a second.
