I Drove The 1,000HP Hennessey Exorcist!

Hennessey Performance took an already track-focused Camaro ZL1 and pushed it to roughly 1,000 horsepower, building a car aggressive enough to earn the name Exorcist. Forrest’s Auto Reviews got behind the wheel to kick off 2018, delivering an unscripted, iPhone-shot drive that shows exactly what four-figure horsepower feels like in a car that started as GM’s factory flagship. Watch the drive and see why the muscle car era’s comeback is more than nostalgia.

A stock Camaro ZL1 already ranks among the most track-capable cars General Motors has ever built. Hennessey Performance looked at that and decided it needed roughly double the horsepower. The result carries a name that isn’t subtle — the Exorcist — and when Forrest’s Auto Reviews got behind the wheel to kick off 2018, the drive that followed makes clear exactly why a car built to exorcise something needs every bit of that four-figure horsepower number to back up its own name.

Starting From an Already Serious Platform

The Hennessey Exorcist doesn’t start from a blank slate — it begins life as a sixth-generation Camaro ZL1, GM’s supercharged, track-focused flagship that already produces well over 600 horsepower from the factory and comes standard with magnetic ride suspension and a genuine road-course pedigree earned on real circuits. Hennessey’s decision to build the Exorcist on top of that platform, rather than a lesser Camaro trim, tells you the goal was never just raw power — it was power layered onto a chassis already fully capable of handling it without falling apart.

Getting to Four Figures

Reaching the 1,000-horsepower mark that gives the Exorcist its name requires Hennessey’s own supercharger upgrade package built specifically around the ZL1’s factory LT4 engine, along with supporting fuel system and tuning work to make that power reliable rather than a one-time dyno-pull number that falls apart under repeated use. It’s the kind of build that separates a serious aftermarket tuner from a shop simply bolting on a bigger blower pulley, because getting an extra four hundred-plus horsepower to actually live on the street requires solving problems the factory never had to solve in the first place.

Tires Were the First Thing to Change

One detail viewers latched onto in the comments was the upgraded tire package — Nitto rubber replacing the factory Goodyears, a change that becomes non-negotiable once horsepower numbers climb into four figures. Getting that much power to the pavement without simply lighting up the rear tires every time the throttle opens requires exactly the kind of tire upgrade Hennessey clearly prioritized before handing the car over for a public review drive with a camera rolling.

A Review Filmed on Consumer Gear

Forrest’s Auto Reviews built this drive using nothing more exotic than an iPhone SE, a handheld gimbal, and a clip-on microphone — a production setup the channel openly shares in its description as a blueprint for anyone wanting to start their own car review channel from scratch. That transparency about equipment is part of what has made channels like this one relatable to an audience of enthusiasts who’d rather watch an honest, accessible review than a heavily produced network segment with a full camera crew.

Hennessey’s Reputation Precedes the Car

Hennessey Performance built its name over decades modifying everything from Dodge Vipers to pickup trucks into four-figure horsepower monsters, and the Exorcist name follows a company tradition of memorable, slightly ominous naming for its most extreme builds. A shop with that track record lends immediate credibility to a claimed 1,000-horsepower Camaro in a way an unknown, unproven tuner never could manage on a first attempt.

The Muscle Car Era’s Unlikely Comeback

One comment beneath the video captures something bigger than just this car: genuine surprise that the muscle car era ever came back at all, after decades of downsizing and emissions concerns seemed to have ended the horsepower wars for good sometime in the 1980s. A supercharged, four-figure Camaro built by an aftermarket specialist and reviewed on a consumer camera setup is exactly the kind of grassroots proof point that the muscle car resurgence isn’t just nostalgia marketing — it’s a genuinely active corner of the performance car world.

Why a Quick Review Still Works

Forrest’s Auto Reviews frames this specifically as “just meant to be a quick review and drive,” and that modest framing undersells how effectively a short, unpolished drive video can communicate what 1,000 horsepower in a Camaro actually feels like — sometimes a five-minute clip of someone genuinely reacting behind the wheel tells you more than a fully scripted, ten-minute production ever could manage with a full script.

Proving the Power Claim Independently

The dyno video linked in the description — a separate clip documenting the Exorcist’s power figures on a rolling road — gives skeptical viewers a way to verify the horsepower claim independently rather than simply taking the reviewer’s word for it, a level of transparency that smaller tuning shops with less to prove often skip entirely.

An Honest Gut-Check, Not a Marketing Reel

Watching an everyday reviewer, rather than a Hennessey factory driver, take the Exorcist out also changes the tone of the whole video — it’s less a controlled marketing exercise and more an honest gut-check of what the car is actually like to drive from someone with nothing to gain from exaggerating the experience.

Branding Extreme Builds Like Their Own Model

The Exorcist name also fits into a broader trend among modern tuning shops of branding extreme builds almost like their own sub-models rather than just “modified” versions of the donor car — Hennessey has done the same with its Venom and Jekyll & Hyde nameplates over the years, turning a heavily upgraded Camaro into something closer to a distinct product line than a one-off custom build.

Why Documentation Protects Resale Value

For anyone shopping the used market for one of these builds years down the road, that branding matters practically as well as marketing-wise — documentation tying a car back to a specific Hennessey package, complete with build sheets and dyno results, tends to preserve resale value in a way that an anonymous, undocumented shop build never quite manages to match.

It’s a small business detail buried under all that horsepower, but it’s exactly the kind of thing that separates a car worth chasing on the used market from one that’s simply loud.

Whether a viewer came for the horsepower number or the honest reaction shots, this drive delivers both in equal measure, which is probably the real reason it’s still getting watched years after 2018 ended.
