The Chevrolet Camaro ZL1 is already a formidable machine straight off the factory floor, boasting a supercharged 6.2-liter LT4 V8 engine that churns out an impressive 650 horsepower. However, for those who believe that there’s no such thing as too much power, Hennessey Performance, the renowned Texas-based hypercar manufacturer and high-performance vehicle creator, has consistently pushed the boundaries. For over 32 years, they’ve been in the business of ‘making fast cars faster’, and their EXORCIST Camaro ZL1 upgrade is a testament to this philosophy. Now, they’re announcing the end of an era with a limited ‘Final Edition’ series of this famed upgrade.
Elevating Camaro ZL1 Horsepower to a Monstrous 1000 HP
The stock Camaro ZL1 is undeniably potent, delivering 650 hp and 650 lb-ft of torque. But Hennessey’s expert technicians take this already powerful foundation and amplify it to an extreme level. Their comprehensive upgrade package for the EXORCIST ‘Final Edition’ focuses on maximizing the Camaro Zl1 Horsepower.
The transformation begins with the heart of the beast – the 6.2-liter pushrod V8. Hennessey replaces the stock supercharger with a larger, high-flow unit and integrates a high-flow air induction system. To ensure the engine can handle the increased demand, the auxiliary fuel system, fuel injectors, and fuel pump are all upgraded.
Moving deeper into the engine, the cylinder heads are meticulously ported, and custom HPE camshafts are installed. Furthermore, critical components like intake valves, exhaust valves, valve springs, retainers, lifters, and pushrods are all replaced with higher-performance alternatives. To manage the increased heat, an oversized heat exchanger is fitted, while long-tube stainless steel headers and high-flow catalytic converters optimize exhaust flow, further contributing to the enhanced Camaro ZL1 horsepower.
Unleashing Unrivaled Performance
Years of dedicated research and development have culminated in the EXORCIST ‘Final Edition’, which is meticulously calibrated with a finely tuned HPE Engine Management software upgrade. This software, working in harmony with the extensive engine modifications, unlocks the full potential of the LT4 engine. The result is a staggering 1,000 horsepower and 966 lb-ft of torque. This represents a phenomenal 54 percent increase in power and a 49 percent boost in torque compared to the stock Camaro ZL1 horsepower.
The performance figures are nothing short of breathtaking. The EXORCIST ‘Final Edition’ catapults from 0 to 60 mph in a mere 2.1 seconds, conquers the quarter-mile in just 9.57 seconds, and achieves a top speed of 217 mph. This level of performance places it firmly in hypercar territory.
The EXORCIST Legacy: A Legend Born to Conquer
The original EXORCIST, launched in 2017, was created with a clear mission: to ‘slay the Dodge Demon.’ At the time, the Dodge Demon, with its 840 horsepower, was considered the king of muscle cars. Hennessey’s 1,000 horsepower EXORCIST decisively surpassed its rival. Now, even with Dodge’s latest Challenger SRT Demon 170 boasting a claimed 1,025 hp on E85 fuel, the Hennessey EXORCIST Camaro ZL1 ‘Final Edition’ remains a force to be reckoned with. Tuned for both the race track and everyday driving, it offers a unique blend of extreme power and refined drivability.
John Hennessey, company founder and CEO, states: “Our comprehensive upgrade to the Camaro ZL1 is one of my all-time favorites. The chassis, suspension, and powerplant work seamlessly together, so all the driver experiences is raw, unbridled horsepower. There’s nothing else like our EXORCIST, so we’re eager to share this special limited edition with fans of this iconic car before it’s gone forever.”
A Collector’s Item: Limited to 57 Units
Adding to its exclusivity, each EXORCIST ‘Final Edition’ engine is adorned with a unique ‘Final Edition X of 57’ serial-numbered engine bay plaque. This commemorates 57 years since the iconic Camaro first entered production, making it a true collector’s item. Complementing the engine badging are distinctive EXORCIST ‘Final Edition’ graphics on the exterior, further setting it apart.
Hennessey stands behind the quality and performance of their upgrades, backing the EXORCIST ‘Final Edition’ with a comprehensive 3-year / 36,000-mile limited warranty. Production of this limited edition model is currently underway.
