American tuning shop Hennessey Performance Engineering has released a video showing a Chevy Camaro ZL1 1LE equipped with its HPE850 performance package being put through its paces on its private test track in Sealy, Texas, allowing viewers to hear its supercharged Small Block roar.
The HPE850 package for the Chevy Camaro ZL1 boosts the output of the sports coupe to an eyebrow-raising 850 bhp at 6,300 rpm and 860 pound-feet of torque at 4,000 rpm. This sizable increase in power comes from an aftermarket lower supercharger pulley, high-flow cylinder heads, an upgraded heat exchanger, upgraded valve springs, upgraded valves, different lifters and pushrods, a high-flow induction system, long tube headers, high-flow catalytic converters and a Hennessey camshaft. All HPE850-equipped Chevy Camaro ZL1 models also come with Hennessey exterior badging and a Hennessey numbered build plaque. The installed Hennessey parts are backed by a two-year, 24,000-mile warranty.
This video shows Hennessey putting an HPE850-equipped Chevy Camaro ZL1 1LE to the test prior to delivery to the customer. This particular car is somewhat unique in that it was delivered in the limited-run Shock exterior color, which was briefly offered on the Camaro lineup for the 2019 and 2020 model years. It also has the 1LE track package, which significantly improves the handling performance of the sports coupe thanks to an aero package, 19-inch sport wheels shod in Goodyear Eagle F1 tires and performance suspension with Multimatic DSSV dampers. The 1LE package also includes red brake calipers with 1LE logos, a Satin Black hood wrap, dark tail lamps and low-gloss mirror caps.
As a reminder, the Chevy Camaro ZL1 comes standard with GM’s supercharged 6.2L LT4 V8 engine, which produces 650 horsepower and 650 pound-feet of torque. Power is funneled to the rear wheels via the standard six-speed manual transmission or the optional GM 10-speed automatic.
