When it comes to world-beating performance, perhaps no name is as ubiquitous as Hennessey Performance. In fact, Hennessey was building 1,000 horsepower cars before building 1,000 horsepower cars was a thing—originally starting with the soon-to-be-extinct Viper and even the occasional Corvette in 1991. Since then, they have been building some of the fastest cars to have ever graced the tarmac, including the Hennessey Venom GT which uses a twin tubo’d LS7 to make more than 1,400 horsepower—1,451 to be exact—and was crowned one of the fastest cars in the world; even going as far as taking the top speed crown from Bugatti Veyron when it blasted to 270.49 mph at the Kennedy Space Center’s 3.2 mile shuttle landing runway.
Needless to say, Hennessey is very familiar with going fast, especially when it comes to LS and now LT motivation. So what else would you expect when they set their sights on the new sixth-generation Camaro other than to break all sorts of records with it? Well, that’s exactly what they did, giving us the world’s first 200 mph sixth-gen. But how did they do it?
First, they started off with John Hennessey’s personal sixth-gen Camaro. And, much like all of us have said at one point or another, he stated “as soon as I got it I knew I wanted to make it faster.” If that isn’t the understatement of the year, we don’t know what is. And while most would be tempted to throw a little boost at the Camaro’s mill, Hennessey Perfomance (HPE) decided to utilize a relatively unorthodox method for achieving top speed records; nitrous.
They started things off with one of their HPE600 packages, which is originally a naturally aspirated build. The heads are CNC ported, hand blended, and the chambers are milled down to up the compression ratio. Lightweight hollow-stem intake and exhaust valves are used and governed by heavy duty dual valve spring with machined locators and locks and titanium retainers. HPE then stuffs the mill with a custom ground bumpstick—the dimensions of which are classified.
The entire valve train is upgraded and a set of Kooks 1 7/8-inch stainless steel long-tube headers and an MSD Atomic Airforce intake manifold help the bullet breath. However, as you can see in the video, the car is still, amazingly, huffing through the stock air box with an upgraded filter element. After tuning, this all typically amounts to 605 horsepower and 542 lb-ft of torque at the crank. But, as we mentioned earlier, this was no standard HPE600 build.
After the car was up to HPE600 specs, a liberal does of nitrous, via Nitrous Outlet, was added to top it all off; bringing the car’s total twist capabilities to 751 horsepower. As for the suspension, Chevrolet Performance provided a lowering kit to help keep air from building up under the car, keeping it much more stable at the speeds it would be seeing.
With the car squared away, the team at HPE headed out to the Continental Tire Proving Grounds, a 8.5 mile oval track, in Uvalde, Texas. With hot-foot Brain Smith behind the wheel, the car easily blasted past the 200 mph target set for the car. At the end, you can detect a hint of hesitancy from Smith as he seems to want to go back out because the car has more left in it. Nevertheless, the goal was to be the first sixth-gen to go 200 mph and John Hennessey saw no point in risking the car again just to squeeze a few miles per hour out of it.
We still can’t believe the howl this thing produces as it tears by the camera. Sit back, and turn it up. We can’t wait to see what the HPE team will do next.
