Hennessey Performance is well-known among Corvette enthusiasts. They have made some legendary performance upgrades and are currently offering upgrade packages for the Corvette C8.
However, the Corvette C7 ZR1 is becoming more coveted by many enthusiasts in the second-hand market. Before the introduction of the C8 Corvette ZR1, the 2019 Chevrolet Corvette ZR1, built for just one year, marked the final evolution of the C7 generation and remains the most powerful production Corvette of its era. At its heart lies the LT5: a 6.2-liter supercharged V8 producing 755 horsepower and 715 lb-ft of torque.
And Hennessey would like to remind you that they are still offering the HP1000 upgrade package for the C7 Corvette ZR1. This performance package elevates the LT5’s output to a staggering 1,000 horsepower and 966 lb-ft of torque, figures that stand toe-to-toe with the C8 ZR1’s 1,064 horsepower and 828 lb-ft.
