Details of the latest run will be announced on April 11.

Hennessey Performance Engineering is going to smash its own world record on Monday, teasing a run that goes past 270.49 miles per hour.

Exceeding 200 miles per hour in anything is impressive. When it's done in a Camaro, though, you know a lot of wrench work has gone into the car in question.

Hennessey Performance's HPE1000 package for the 2016 Chevy Camaro SS adds a supercharged and strokes the engine to 6.8 liters to make 1,000 hp.

Hennessey Captures 0-170 MPH Sprint On Video

Hennessey puts the 2016 Ford Mustang Shelby GT350 on the dyno, and runs it to 170 mph to establish a power baseline for its supercharger package.

Top Gear has staged a short drag race between a Hennessey VelociRaptor and a Land Rover Range Rover Sport SVR. Watch to see which one of these supercharged V8s wins.

Hennessey has kept tweaking the Mustang to create the 774-horsepower HPE750. The supercharged pony car recently hit a GPS-verified 207.9 miles per hour at the Continental Tire Proving Grounds in Texas, and it was all captured on video.

John Hennessey took his personal 2015 HPE700 Supercharged Ford Mustang to the Continental Tire Proving Grounds in Texas to see just how fast the muscle car would go. It managed 195.4 miles per hour when it hit the limiter going down the straight.

Hennessey has done it again, improving the claimed record-holding top speed of its Venom GT to 270.49 miles per hour. The record run was made on February 14 on the 3.22-mile landing runway at the Kennedy Space Center in Florida. The speed was confirmed by a Racelogic Vbox telemetry system, but for a variety of reasons, it will not make it into the Guinness Book of World Records. However, it narrowly beat out the record-holding top speed of the Bugatti Veyron Super Sport at 267.81 mph. Amazingl

Hennessey has a proud history of tuning high-performance machinery from General Motors and taxing it out onto Grand Parkway, a new stretch of toll road on the outskirts of Houston, Texas. That's what it did with the Cadillac CTS-V, spooling its twin turbochargers until it cracked 220 miles per hour. It did the same with the Corvette Stingray, feeding it nitrous all the way up to 200 mph. Now it's time for the new Chevy SS.

We knew that once Hennessey Performance got its hands on the seventh-generation Chevrolet Corvette Stingray, big things were going to happen. A 200.6-mile-per-hour run on a closed section of Texas' brand-new State Highway 99, was just a shade bigger than what we were expecting. The run was also a test of the new toll road - which Hennessey founder John Hennessey called "perfectly smooth" - and the RFID toll system, which was still able to tag the Corvette at 200 miles per hour (toll dodgers bewa

Chevrolet's latest road rocket, the Corvette Stingray, is a very quick car. If one needs further proof of that, we recommend they take a look at this video from Hennessey of what is claimed to be the first privately owned C7 Corvette to make a pass down the quarter mile. Not just any quarter mile, mind, this black C7 blitzed its way down the tuner's primary testing dragstrip. The Chevrolet ran the quarter in just 12.23 seconds at 114.88 miles per hour. That is a very quick time for a stock car.

Hennessey Performance Engineering has created an HPE650 package for the Jeep Grand Cherokee SRT fitted with the 6.4-liter Hemi engine. When it leaves the showroom floor it has 470 horsepower and gets from 0-60 miles per hour in 4.8 seconds. When it leaves Hennessey's garage floor after the upgrade it has 650 horsepower – 530 hp at the wheels, according to Hennessey – and gets to 60 mph in 3.9 seconds on its way to running the quarter-mile in 12.6 seconds.

We said they'd probably be out with an official video, we did not lie. The Hennessey-powered camouflage Ford GT sat at one end of the runway at the Texas Mile sitting still. At the other end of the runway it had broken its own speed record, the twin-turbo 5.7-liter V8 pushing the aerodynamic supercar up to 267.6 miles per hour, a 4.3-mph improvement over the old mark.

The record-setting Hennessey-powered camouflage Ford GT we showed you at this time last year headed back to the Texas Mile and managed to bring home yet another record. As you may recollect, last year saw Mark Heidraker's machine sprint to a record 257.7 mph thanks to propulsion from its twin-turbo 5.7-liter V8. The big mill sucks down race gas, and this year the creation pulled off a 267.6-mph run over the weekend. That feat set a new record for the event. Something tells us neither Heidraker n

We're happy there's a John Hennessey who walks the Earth. While any number of humans may have had the idea of marrying a stretched Lotus with a twin-turbocharged ZR1 engine, only Hennessey had the wherewithal to make the Venom GT. And because he has, we bring you the news that the Venom GT has officially broken the world record for a car traveling from 0 to 300 kilometers per hour.
