Camaro Dyno-Mite: Hennessey HPE550 Camaro Dyno Smack Down

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.show less...
