Since 1991, Hennessey Performance Engineering has been transforming normal cars, trucks, and SUVs into some of the fastest non-supercars around. One of the most attention-grabbing examples from recent years was Hennessey’s extreme version of the Chevrolet Camaro ZL1, dubbed the Exorcist and limited to 100 examples. As if that wasn’t exclusive enough, the Texas-based tuner has just announced a 30th Anniversary edition of its 1000 hp Camaro that will be even more rare.

What is the Exorcist?

Hennessy launched the original Exorcist a few years back, using the 2017+ or 6th Generation Camaro as a foundation. The name is a play on words and came about as a response to Dodge’s release of the 840 hp Challenger Demon. Hennessey had already reached 850 hp in the Camaro ZL1 with its HPE850 builds, but in the aftermarket tuning world there’s always room for improvement.

In order to have a real shot at exorcising the Dodge Demon, the Camaro ZL1’s engine needs just a bit more room to breathe. With the new target of 1000 hp, Hennessey Exorcist packages do away with the factory supercharger and replace it with a bigger one, typically a 2.9 liter Whipple twin-screw design.

Alternatively, a roots-type Magnuson supercharger with 2.65 liters of displacement may be used, if a customer requests the option. In either case, the added displacement of an aftermarket blower is the key to moving larger volumes of air and reaching the 1000 hp mark safely. To support the massive increase in power, Hennessey Exorcist packages also include a better heat exchanger, intake system, and ported cylinder heads, among other upgrades.

What is special about the 30th Anniversary Exorcist?

The new models will be serialized with a special 30th Anniversary Edition number plate on the chassis. They also receive unique badging on the front fenders, in addtion to the standard Exorcist stripes and decals on the rear fenders.

Powertrain specs and performance figures remain the same as the earlier model, but only 30 of the anniversary editions will be produced, so these will be the rarest examples in an already limited production run of 100 units. Once all 30 of the anniversary editions are made, production of the Exorcist Camaro will cease, ensuring the exclusive nature of the vehicle.

Multiple options for the Gen 6 Camaro ZL1

Hennessey offers the 30th Anniversary Exorcist as a turnkey finished product in both coupe and convertible form, with the option of converting your own Camaro ZL1 instead. In either case, spectacular performance is the end result, with a quoted 0 to 60 mph time of 2.1 seconds and top speed of 217 mph.

“The Exorcist is the epitome of the American Muscle car and has the off-the-line performance to embarrass almost any car on the planet,” said company founder and CEO John Hennessey. “We’ve been making fast cars faster since 1991, so our 30th Anniversary Exorcist pools all we know into one ferocious supercar slayer.”

With automakers releasing new models for 2021 and 2022, it’s a good bet that Hennessey Performance is already working on the next batch of sleepers, just waiting for a chance to surprise unsuspecting supercar drivers.
