Hennessey Perfromance ’s most recent projects included power updates for the 2014 Corvette Stingray and 2014 Chevrolet SS . If you’ve been with us the past couple of months, you may also know that its Lotus Exige -based Venom GT is the world’s fastest production car, albeit an unofficial record, at 270.49 miles per hour.

But these aren’t the only vehicle Hennessey has meddled with in its Texas workshop lately. The company has added its familiar HPE700 package to a couple of European sports cars , such as the recently-discontinued McLaren MP4-12C and the Ferrari 458 Spider, as well.

Tuning an already fast Ferrari 458 might sound insane to some, but nothing’s too extreme for the folks over at Hennessey, who have added a pair of ball bearing turbochargers in order to increase output up to a neck-breaking 738 horses and 532 pound-feet of torque.

The twin-turbo Ferrari was also enhanced with a new fuel system, a stainless steel exhaust system, among other goodies, while being fitted with the HPE Engine Management Calibration for optimized performance.

These updates enables the Texas-tweaked 458 Spider to launch from 0 to 60 mph in only 2.8 seconds and complete the quarter mile in 10.5 seconds at 137 miles per hour.


Had it not been for some silly rules, like needing 30 production cars to qualify and needing two back-to-back runs, the Hennessey Venom GT would have taken home the title as the "World’s Fastest Production Car" after its 270.49-mph run at Kennedy Space Center. But those rules are in place, and Hennessey couldn’t care less, as it is rolling out a special World’s Fastest Edition Venom GTs in very limited quantities.

There is very limited information on the World’s Fastest Edition, but we do know that it features a red, white and blue livery to match the American flag. We also learned that the model will come in at a price tag of $1.25 million.

According to what I can gather, the Venom GT WFE will carry the same 7.0-liter, twin-turbo V-8 as the rest of the Venom GTs. This means that it pumps out 1,244 horsepower, and shoots the hypercar to 60 mph in 2.7 seconds and 186 mph in just 13.63 ticks. While the Venom GT only hit 270.49 mph at Kennedy Space Center, Hennessey claims it can hit about 278 mph.

I’m sure that Hennessey will announce more details on the WFE Venom GT, if there is more to talk about, so stay tuned to TopSpeed.com for more details.

We all know that the Bugatti Veyron is the current record holder as the world’s fastest production car, and that just didn’t sit right with John Hennessey and his team. So, they set out to destroy the record, bringing the title back to the good ol’ U.S. of A. After negotiating with NASA to use its landing strip at the Kennedy Space Center, the record was prime for the taking.

Well, as expected, the Venom GT was the car for the job, and it completed its end of the task by hitting a Vbox-verified 270.49 mph — the Veyron Super Sport topped out at 267.81 mph. Unfortunately, Guinness Book of World Records again catered to Bugatti, as it will not recognize the record because NASA only allowed one run, and the record book requires two runs — down and back — to confirm the average top speed.

So, why didn’t Hennessey negotiate for one more pass down the landing strip? That’s because it would have been pointless, as Guinness defines a "production car" as one with at least 30 examples built and Hennessey only has 29 slotted for production this year.

Well, I say screw Guinness and their Bugatti -loving tactics has confirmed that it can smoke the Veyron, plus it is better looking and cheaper — a win-win-win!

Shortly after Chevrolet launched the SS sports sedan onto the market Hennessey Performance came up with a pretty amazing tuning kit that raised the standard output up to 600 horsepower — up from 415 horsepower.

A few weeks ago, we got a look at the Hennessey SS hitting a top speed of 163 mph on a Texas Toll Road, and today the tuner released a video of the sports sedan running the quarter mile in 11.84 seconds at 117 mph. To put that into perspective, a Ferrari 458 Italia runs the quarter in about 11.5 ticks at 125 mph — not too bad for a sedan.

The only update the model received besides that bad-ass HPE600 kit was a set of drag radials for extra grip.

As a reminder the HPE600 package includes a TVS2300 supercharger, HPE air induction system, fuel system upgrades and ECU modifications. A series of aesthetic updates were also made, including a carbon aero body kit and a carbon-fiber kit for the interior.

Hennessey Performance revealed one of the first tuning kits for the seventh-generation Chevrolet Corvette last July, and the best part is that the tuner offers four different power kits — HPE600, HPE700, HPE800 and HPE1000 — with the output level ranging from 600 to 1,000 horsepower.

The tuner took one of this kits — the HPE700 — and strapped it onto the dyno to see what the car is really capable of. The HPE700 includes a TVS2300 supercharger system and Hennessey’s in-house HPE Air Induction System, CNC ported heads for free-flowing air and exhaust, and a hot camshaft.

As a result of all of this hard work and engineering, the Stingray HPE700 delivers a total of 700 horsepower at 6,300 rpm — up from the standard 460 horsepower at 6,000 rpm and 465 pound-feet of torque at 4,600 rpm.

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.
