The legendary Chevrolet Camaro ZL1, a powerhouse of American muscle, gets an even more formidable send-off thanks to Hennessey Performance. The renowned Texas-based hypercar manufacturer and high-performance vehicle creator has announced the limited-production ‘Final Edition’ series of its celebrated EXORCIST Camaro ZL1 upgrades, marking the end of an era for this iconic enhancement.
From the factory, the Chevrolet Camaro ZL1 already boasts a potent 6.2-liter supercharged LT4 V8 engine, delivering an impressive 650 horsepower and 650 lb-ft of torque. However, Hennessey’s team of expert technicians, with over 32 years of experience in ‘making fast cars faster,’ elevates this performance to a whole new level. They meticulously enhance the Camaro’s pushrod V8 with a suite of significant upgrades. These include a larger, high-flow supercharger and a high-flow air induction system to maximize airflow. The auxiliary fuel system, fuel injectors, and fuel pump are also upgraded to meet the demands of the increased power.
Delving deeper into the V8 engine, Hennessey’s upgrades continue with ported cylinder heads and custom HPE camshafts. The intake valves, exhaust valves, valve springs, retainers, lifters, and pushrods are all replaced with higher-performance components. To manage the increased heat, an oversized heat exchanger is installed for enhanced cooling. Breathing is further optimized with long-tube stainless steel headers and high-flow catalytic converters, ensuring the engine operates at peak efficiency.
Years of rigorous research and development have culminated in the EXORCIST ‘Final Edition,’ which is finely calibrated with a specifically tuned HPE Engine Management software upgrade. This crucial enhancement, in conjunction with the comprehensive engine overhaul, unlocks the LT4 engine’s true potential, resulting in a staggering output of 1,000 horsepower and 966 lb-ft of torque. This represents a remarkable 54 percent increase in power and a 49 percent boost in torque over the stock Camaro ZL1. The performance figures are nothing short of breathtaking. The EXORCIST ‘Final Edition’ rockets 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. For enthusiasts seeking ultimate performance, especially those considering the track-focused capabilities often associated with models like the Camaro Zl1 1le, the EXORCIST delivers an unparalleled driving experience.
The original EXORCIST, launched in 2017 on the sixth-generation Camaro Alpha platform, was famously created by Hennessey to ‘slay the Dodge Demon.’ At the time, the Demon, a rival supercharged Challenger with 840 hp, seemed formidable, yet it paled in comparison to Hennessey’s 1,000 hp EXORCIST. Today, Dodge has responded with the dragstrip-tuned Challenger SRT Demon 170, boasting an E85-fueled 1,025 hp. Despite this increase in competition, the Hennessey EXORCIST Camaro ZL1 ‘Final Edition’ – meticulously tuned for both racing circuits and everyday driving – remains a dominant force.
John Hennessey, the company founder and CEO, stated, “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.”
To further emphasize the exclusivity of these models, each upgraded powerplant 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, adding a historical significance to this final edition. The engine badging is further complemented by distinctive EXORCIST ‘Final Edition’ graphics on the exterior, setting these models apart.
Hennessey stands behind the quality and performance of the EXORCIST ‘Final Edition’ upgrade with a comprehensive 3-year / 36,000-mile limited warranty. Production of this highly sought-after model is already underway.
