The Chevrolet Camaro ZL1 is already a beast straight from the factory, boasting a potent 6.2-liter supercharged LT4 V8 engine. This powerhouse delivers an impressive 650 horsepower and 650 lb-ft of torque, making it a formidable machine on both the road and track. However, for those craving even more exhilarating performance, Hennessey Performance, a renowned name in high-performance vehicle tuning, has consistently pushed the boundaries. Their latest creation, the EXORCIST ‘Final Edition’, marks the end of an era, taking the Camaro Zl1 Horsepower to an astonishing new level.
The standard Camaro ZL1 horsepower is certainly nothing to scoff at. Chevrolet engineered the LT4 engine for significant power, utilizing features like direct injection and a high-efficiency supercharger to achieve its заводские numbers. This stock configuration provides thrilling acceleration and a top speed that satisfies most performance enthusiasts. Yet, Hennessey saw an opportunity to unlock the LT4 engine’s untapped potential, transforming the already potent Camaro ZL1 into the legendary EXORCIST.
Hennessey’s team of expert technicians, with over three decades of experience in enhancing fast cars, meticulously upgrades the Camaro ZL1’s engine. The transformation begins with a larger, high-flow supercharger and a high-flow air induction system to force-feed the V8 with more air. The fuel system is also significantly enhanced with upgrades to the auxiliary fuel system, fuel injectors, and fuel pump to meet the demands of increased power. Internally, the engine receives ported cylinder heads, custom HPE camshafts, and upgraded intake valves, exhaust valves, valve springs, retainers, lifters, and pushrods. To manage the increased heat, an oversized heat exchanger is installed, while long-tube stainless steel headers and high-flow catalytic converters improve exhaust flow, optimizing performance and sound.
The result of these comprehensive upgrades is a staggering 1,000 horsepower and 966 lb-ft of torque. This represents a 54 percent increase in power and a 49 percent increase in torque over the stock Camaro ZL1 horsepower figures. The performance gains are nothing short of breathtaking. The EXORCIST ‘Final Edition’ accelerates from 0-60 mph in a mere 2.1 seconds, conquers the quarter mile in just 9.57 seconds, and achieves a top speed of 217 mph. These figures place the EXORCIST in hypercar territory, demonstrating the immense power Hennessey has extracted from the Camaro ZL1 platform.
Originally conceived in 2017 to challenge the Dodge Demon, the EXORCIST quickly established itself as a benchmark for Camaro ZL1 horsepower and overall performance. Even with Dodge’s release of the Challenger SRT Demon 170, boasting over 1,000 horsepower, the Hennessey EXORCIST ‘Final Edition’ remains a formidable contender. Its focus on both track prowess and everyday drivability makes it a unique and highly desirable performance machine.
As John Hennessey himself 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.”
Each EXORCIST ‘Final Edition’ engine is distinguished by a special ‘Final Edition X of 57’ serial-numbered plaque, commemorating 57 years of the Camaro legacy. Exterior EXORCIST ‘Final Edition’ graphics further set these limited-edition models apart. Backed by Hennessey’s 3-year / 36,000-mile warranty, the EXORCIST ‘Final Edition’ offers both extreme performance and peace of mind. For enthusiasts seeking the ultimate expression of Camaro ZL1 horsepower, the Hennessey EXORCIST ‘Final Edition’ represents a rare and exceptional opportunity.
