When Chevrolet announced the seventh-generation Corvette , it also announced an estimated top speed of 180 to 190 mph, which is light years behind the 200 mph barrier that separates supercars from sports cars. However, with the upgrades announced by Hennessey Performance, the HPE700 Corvette was able to hit a supercar -like 200.6 mph.

This amazing speed was hit on the Texas State Highway 99 and was witnessed by officials from TxDOT, Texas DPS and TransCore.

The HPE700 kit announced by Hennessey adds a TVS2300 supercharger system and Hennessey’s in-house HPE Air Induction System, engine calibration and CNC-ported heads for free-flowing air and exhaust. As a result, the car’s standard 460 horsepower is increased to an incredible 700 horsepower at 6,300 rpm.

With the extra 240 horsepower it was pretty easy for the Stingray to score such a great result. Check out the above video to see this monster Corvette in action.

How often do you think, the 2014 Chevrolet SS does not produce enough power? Apparently, it is a performance sedan with over 400 horsepower crammed into its engine bay and still, it isn’t enough for many motorheads. More is always better and in the case of the Chevrolet SS and its V-8 powerplant, there’s even more to be had than just 415 horsepower.

Callaway was first to come forward to inject some pop into the 6.2-liter, V-8 engine with a nice tuning package. With it, the Chevrolet SS pumped out 570 horsepower and 535 pound-feet of torque. Now, that’s what you call a performance sedan. At least, Callaway seems satisfied with the output.

Our friends from Texas aren’t far behind either. Hennessey Performance has put up a teaser video of what we could expect form the world-famous tuning house. The video shows a base-line dyno run of the 2014 Chevrolet SS sedan. On the dyno, the SS clocks 359 horsepower at the wheel and 367 pound-feet in factory-spec, which seems about right.

Although, information about the Hennessey-tuned Chevrolet SS is scarce, we believe Hennessey could be aiming for an output figure of around 600 horsepower. This may be slightly more than the Callaway SS, giving Hennessey a slight lead in tuning the next great Chevrolet sedan .

It’s hard putting a price on awesome yet somehow, Hennessey never fails to deliver. The US aftermarket company has time and again developed some of the wildest tuning projects imaginable and its no different with its program for the 2013 SRT Viper .

Who cares if the Viper’s sales are lagging; when you have Hennessey develop a program like the Venom 700R , you’re going to be tripping over yourselves to scoop up a Viper and get the project done.

On its own, the SRT Viper is capable of producing 640 horsepower and 600 pound-feet of torque, good enough to hit 0-60 mph in 3.3 seconds to go with a top speed of 206 mph. But with the Venom 700R program installed, the Viper’s output goes up to an incredible 705 horsepower and 695 pound-feet of torque, numbers that allow it to hit 0-60 mph in 3.1 seconds to go with a top speed of 216 mph.

That’s crazy in every imaginable way you look at it. Then again, Hennessey has made a habit of turning anything it builds into something crazy.

Hennessey took its powerful Venom GT and the Nissan GTR HPE750 to Circuit Of The Americas for some media rides during the ALMS and WEC races on September 20th and 21st. This video shows the Venom GT in action on the famous F1 circuit and it was filmed with a GoPro camera installed on the GT-R.

As you probably know by now, the Venom GT is based on a Lotus Exige and it’s powered by a Corvette ZR1 -sourced 6.2-liter, supercharged V-8 engine. In its base setup, this engine delivers a total of 725 horsepower, but in the top version it can be raised to 1,200 horsepower. The Venom GT can sprint from 0 to 60 mph in 2.5 seconds and to 200 mph in 15.9 seconds. The tuner reported a top speed of 275 mph.

While the sound is not at its best quality, the video is surely worth watching, so enjoy!

Hennessey unveiled its HPE800 Kit for the McLaren MP4-12C for the McLaren MP4-12C in early 2012. In that instance, Hennessey tuned the supercar to deliver a total of 800 horsepower.

In 2013, however, Hennessey revisits the MP4-12C and came up with a new HPE700 kit that, despite delivering "only" 704 horsepower, it’s still bound to be a hoot to drive.

The new HPE700 kit includes an optimized ECU, an upgraded intercooler, dual air induction filters and a stainless-steel sports exhaust system. Thanks to these changes, the car’s 3.8-liter, twin-turbo V-8 engine’s output was increased from the base 616 horsepower up to a total of 704 Horsepower at 7,500 rpm and a peak torque of 538 pound-feet at 5,800 rpm.

With the extra power, the MP4-12 will sprint from 0 to 60 mph in just 2.8 seconds and will run the quarter mile in 10.3 seconds at a speed of 137 mph.

When a new performance ride hits the market, like the 2014 Corvette Stingray , it is only a matter of time before Hennessey engineers get to cracking the code to drawing more horsepower from it. About a month after GM unveiled the all-new Corvette Stingray earlier this year, Hennessey let us in on the secret that it planned to tune the new sports car to upwards of 1,000 horsepower in several stages.

Today, just five months after making that bold announcement, Hennessey has outlined the details of its new HPE tuning programs for the Stingray . We are just a tad bit impressed, as Hennessey created four equally amazing kits for the Corvette that pushes it to between 600 and 1,000 ponies. So, if the stock 455-horsepower output just isn’t enough for you, you can rest assured that Hennessey has the right kit for you.

What’s great about Hennessey programs is that its engineers and designers never focus solely on muscle. They also turn their attention to updating the suspension, braking and aesthetics to help push the envelope of performance a little further.

We’re pretty sure that if you want to buy an American sports car this year, you may opt for the SRT Viper , and not the new Corvette Stingray .

Hennessey is far and away one of the best American tuners and this time the tuner focused its attention on a Jeep Grand Cherokee SRT8 . Equipped with the tuner’s HPE650 package, the model was taken to the racetrack and put to the test on the 1/4-mile.

The results were pretty impressive for the Grand Cherokee , as it ran the 1/4-mile in 12.6 seconds at a speed of 110 mph. The updated SUV sprints from 0 to 60 mph in just 3.9 seconds.

The HPE650 package includes: new ported cylinder heads; a custom air intake; a TVS2300 supercharger; stainless-steel, long-tube headers; an upgraded fuel system; and an optimized ECU. With these updates, the SRT8 delivers a total of 650 horsepower - up from the standard 470 horsepower.
