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.

Insane to discontinue the Camaro.
It is neither a small or a big block, it is the current Chevrolet V8 engine.
The Camaro Chevrolet is afraid to build! They forgot how to mix green paint also!
It sounds okay. All it needs is the right set of glass pack muffers to give it that Harley Davidson rumble kind of sound. Flowmasters suck and those round fart sounding mufflers suck too. The best sounding car that I ever heard was a 1969 Dodge Hemi Coronet with Continental Blue Swinger glasspacks. I’m a big fan of glasspacks but the newer ones don’t sound as good as the old timey ones like the Orange Peelers, Big Daddy, Golden Goose, and the purple silver and white Thrush mufflers
Don’t like the sound of screws, dog bones, other high pitchs, even tho means power.
Love the sound of my L99 after the resonator delete (made popping sounds hot start up or deceleration), add X pipe 20% larger diameter cat back Magnaflow exhaust. Lower tone and much smoother idle. Not obnoxious at all. Raise RPM and the tone goes into the Golden Mean area, while flowing more air. Sounds like POWER.
You can zip around not much noise at all, or get on it, and the decibels go up.
Just need a cam lope at idle. Have the kit. Needs install.
Think the acceptable sound level got me a pass recently, after wheel hop nonsense at an intersection. Got out of it, doing 33mph in a 25mph zone, cop with his window down in cold weather, looking for a pull over. Where 25 goes to 35, or the opposite way, depending on travel direction. Cop small town this side of 25, me going out of town.
If too loud before they can see you, any nonsense after likely more negative attention.
Low deep at idle, up into mid range stroked NA power.
