Hpe550 Videos

FOR FULL COMPARISON @ INSIDELINE.COM: http://www.edmunds.com/insideline/do/Drives/Comparos/articleId=151466 These are the heavy hitters. The big dogs. They're not playmakers or finesse artists and they don't dish out assists. If the 2010 Ford Shelby GT500 is Dick Butkus snuffing out a Jim Brown thrust up the middle, then the 2010 Hennessey Performance Engineering Chevy Camaro SS HPE550 is Lawrence Taylor with radar lock on Joe Theismann's right leg. And it's not just that they're powerful and merciless, but intentionally provocative and intimidating, too. On looks alone, either of these cars is enough to make the drivers of other machines cower like a three-legged Labradoodle. They are, of course, muscle cars in the rawest, most vicious sense of the term. And they're quicker, faster, meaner and flat nastier than anything built back when Ol' Shel and Don Yenko were just guys. And not by a little bit either. But which is the better beast? To find out, we drove these two all-Americans on the street, at our test track and on the Dynojet chassis dyno at MD Automotive in Westminster, California. Then we did some big smoky burnouts just to piss off the Sierra Club. By the time we were through, Greenpeace had threatened to blockade the Inside Line garage and the Obama administration was seriously considering a unilateral deployment of the fun police. Didn't matter. By then the tires were shot and we had our winner.

MORE HENNESSEY CAMARO INFO @ INSIDELINE.COM: http://blogs.edmunds.com/straightline/2009/06/hennessey-hpe550-camaro-smacks-down-the-dyno.html?tid=edmunds.il.home.photopanel..1.* What's that? You're a power addict and the 426 horsepower with which Chevrolet endowed the 2010 Camaro SS is weaksauce? Here's your fix. The orange 2010 Camaro SS you see above has been given the full Texas-style treatment, and I'm not talking about barbeque. Hennessey Performance Engineering, headquartered in Sealy, Texas, coerces more power out of more than just Mopars and Mitsubishis these days, and he's turned his attention to Chevy's latest pony car. It's called the Hennessey HPE550. The centerpiece of the conversion is the breathing enhancement delivered by a Magnuson Roots-style blower and liquid-to-air intercooler. Supplementing the 6 psi generated by the supercharger is a cold-air intake and free-flow exhaust. Owner John Hennessey tells us that the package swells peak power to 562 hp as measured at the flywheel. Aftermarket horsepower claims are notoriously optimistic, so we did the obvious thing and strapped it to MD Automotive's Dynojet in Westminster, California. The result was anything but weaksauce. Click the jump for the dyno chart and video. First, a caveat. Before we did any dyno runs, we noticed that the insides of our HPE550 test car's tailpipes were curiously free of the typical fine sooty layer that coats every car that runs on pump gas. Instead, they were fairly clean save for a light gray coating.
