Hennessey built the Exorcist Camaro ZL1 to push a factory 650 horsepower platform to 1,000 horsepower and a 217 mph top speed. A larger supercharger, custom camshaft, and ported heads make the jump possible without sacrificing the factory warranty structure. A Final Edition run of just 57 cars marked 57 years of the Camaro nameplate.
When a tuning company like Hennessey that’s at the top of its game, there aren’t a lot of places to go to when wanting to make an even bigger impression on the industry. But the American tuner seems to have done just that with its latest humdinger of a project. Is it a coincidence that this new turnkey masterpiece to come out of the tuner’s garage is called “The Exorcist?†I don’t think so since the Exorcist is all the things its name says it is. It’s all sorts of heavenly horsepower goodness, or as Hennessey claims, 1,000-horsepower’s worth.

Numbers alone rarely capture what a car like this actually does to a straight line, but the Exorcist comes close to forcing the issue. Hennessey backs its 1,000 horsepower claim with a 0-60 mph run of just 2.1 seconds, a quarter mile pass of 9.57 seconds, and a top speed of 217 mph, figures that put a modified Camaro in territory usually reserved for seven-figure exotics. Getting there required more than bolting on a bigger blower and hoping for the best. The version Hennessey eventually built to mark a major Camaro anniversary took things a step further, and only a handful of buyers will ever own one.
The Numbers That Push a Camaro Into Exotic Territory
The stock Camaro ZL1 already arrives with a 6.2 liter supercharged LT4 V8 producing 650 horsepower and 650 lb-ft of torque, which is serious output on its own. Hennessey pushes that to 1,000 horsepower and 966 lb-ft of torque, a 54 percent gain in power and a 49 percent gain in torque, using a larger and higher-flowing supercharger along with a custom camshaft, ported cylinder heads, and high-flow catalytic converters to keep everything breathing properly at that output level.
Only 57 Cars Will Ever Wear the Final Edition Badge
Hennessey eventually introduced a Final Edition version of the Exorcist limited to 57 examples, a number chosen to mark 57 years since the Camaro nameplate first went into production. Every Final Edition car is backed by a 3-year, 36,000-mile limited warranty, an unusual guarantee for a build producing this much power over a factory engine.
Reaching 217 mph and covering the quarter mile in under 10 seconds is not something many street-legal cars can claim regardless of price, and it is worth remembering this all starts from a Camaro platform GM originally engineered for a 650 horsepower ceiling. The gap between that starting point and where Hennessey ultimately took it is the entire reason the Exorcist name stuck.
