When McLaren released the MP4-12C, there were some questions about the distinctiveness of its styling, but not about whether the engineers at Woking had extracted every bit of performance they could from its 3.8-liter twin-turbo V8 engine. John Hennessey and company, however, think they can do better. That's why Hennessey Performance Engineering has targeted the 12C for its latest tuning package.

Traditionally, Hennessey usually starts by bolting on a pair of turbos to whatever car it can get its hands on. But McLaren has already done that, so Hennessey has fitted new ones, and along with it, upgraded the intercooler, intake, exhaust, electronic control modules and transmission. It's also fitted a CarbonAero body kit, new wheels with Michelin Pilot Super Sport rubber and a redone interior swathed in carbon, leather and Alcantara.

The result is 800 horsepower, up from 592 stock. What Hennessey hasn't touched, however, are the MP4-12C's suspension and brakes, which the Texas-based tuner didn't feel it could improve upon. Whether the rest is advisable is up for debate, but that's never stopped the Texas tuner before, so check out the details in the press release after the jump and the renderings for a closer look at what to expect should any McLaren owners inexplicably feel their 12C is just too slow.

Hennessey Performance Transforms McLaren MP4-12 from Mild to Wild with HPE800 Twin Turbo
January 31, 2012

SEALY, TEXAS – Texas-based automotive tuning company, Hennessey Performance (HPE), has set their sights on taking the new McLaren MP4-12C to a higher level of performance. Today the company is introducing their HPE800 Twin Turbo concept for the 12C. The HPE800 Twin Turbo will include upgrades to the powertrain designed to reliably increase power to over 800 bhp. HPE will also add a more aggressive aero package to the vehicle in order to increase downforce. The Hennessey CarbonAero bodywork will incorporate a new, center-positioned frontal air inlet with hood extractor. This new design will allow room for larger heat exchangers for improved engine intercooling as well as transmission cooling.

"We've been taking fast cars and have been making them faster for over twenty years," said company founder and president John Hennessey. "I spent a lot of time around the new 12C at the 2011 Goodwood Festival of Speed and was very impressed. We're excited to have the opportunity to take a great car and give it our own special performance touch while giving 12C owners a uniquely aggressive appearance".

HPE800 Twin Turbo Upgrades Include:
- Upgraded intercooler system
- Upgraded air intake system
- Upgraded ball-bearing turbochargers
- Hennessey titanium exhaust system
- External wastegates
- External blow-off valves
- Upgraded fuel and engine management system
- Upgraded transmission cooler
- Upgraded transmission clutch system
- Custom dyno-tuned engine calibration
- Hennessey Warranty

Other Upgrades Include:
- Hennessey CarbonAero body upgrade
- Hennessey Monoblock wheels
- Michelin Pilot Super Sport Tires
- Hennessey custom interior upgrades including carbon fiber, Alcantara and leathers

HPE does not plan to offer any kind of a suspension or brake system upgrade as the factory systems will be difficult to improve upon. The company plans to offer the upgrades listed above as an entire package as well as some individual parts. These items will be available directly from HPE facilities located in Texas and Southern California. Pricing has not yet been set.


About Hennessey Performance

Hennessey Performance was founded in 1991 as an extension of John Hennessey's competitive spirit, engineering creativity, and burning desire to keep finding ways and events that allowed him to go faster.

In a whirlwind of speed related events over the span of that year, John Hennessey and his self-modified, daily driver Mitsubishi 3000 GT commuted to and participated in a diverse combination of speed events that included Nevada open road races, the Pikes Peak Hill Climb and a record setting 173-mph run at the Bonneville Salt Flats.

John was obviously hooked on racing, but he realized that he wasn't alone in his need for speed. Already a successful entrepreneur in the environmental services industry, and looking for ways to supplement his ravenous racing budget, John saw the potential for turning his automotive passion into his life's work by taking the knowledge and development skills he had gained through racing and probing the performance potential of his car to others with similar cars and speed-focused ambitions.

The first few years saw John's efforts concentrated on building and modifying turbocharged imports such as the Mitsubishi 3000 GT, Toyota Supra and Mazda RX7. But in March 1993, the future and successful growth of Hennessey Performance was set into motion when a customer, impressed by John's winning drives in the Nevada open road challenge events, came to him with one of the first Vipers in the country seeking modifications that would make him competitive in similar events.

Those modifications and tuning resulted in an increase of about 100 more horsepower, prompting John to dub it the Hennessey Venom 500 Viper. The car's subsequent 164-mph average run in the Silver State Challenge drew the attention of the automotive media as one of the first, if not the first, Viper to participate in any form of competition.

The next few years saw demand for Hennessey enhanced Vipers, including cars built for Jay Leno, Bob Lutz and other Chrysler executives, increase to the point that by 1996, Hennessey Performance was dealing exclusively in the V10 Chrysler super sports car. To meet this demand, the company had grown to over a dozen employees and was operating out of a 30,000 square-foot hangar at the Houston airport.

In 2005, once again a new customer provided the means for a major change in the growth and direction of Hennessey Performance. Don Goldman had taken early retirement from a successful career of acquiring, growing then selling businesses to concentrate on his passion of car collecting. His desire to build a Ford GT capable of doing well over 200 mph on a mile long course initiated a successful diversification for Hennessey Performance into building high performance Ford GTs.

Don Goldman was also instrumental in mentoring and partnering with John on the 2004 acquisition of the Lonestar Motorsports Park drag strip facility and subsequent acquisition, in early 2008, of the adjacent property that is now includes the headquarters of Hennessey Performance Engineering.

During this period, John was watching what another friend and customer Bob Lutz was planning in terms of performance cars in his new role at General Motors. When the Cadillac CTS V arrived in 2008, Hennessey Performance was ready with modifications that could put out 650 horsepower from its Corvette derived V8. That same year also saw the design and development of the Venom GT ultra exotic sports car in England.

Building on its success with the Cadillac CTS V, Hennessey Performance became one of the first aftermarket companies to offer high performance models of the Camaro when it arrived.

Don Goldman officially became a partner in Hennessey Performance in June 2009 to oversee the management and operations of the company allowing John to concentrate fully on his passion for product design and development. In contrast to John's one man, apartment based startup operation in 1991, Hennessey Performance currently has 30 employees based in a 30,000-square foot facility off Interstate 10 about 45 minutes west of Houston.

In addition to administrative offices and a customer showroom, facilities include 20 service bays, 16 vehicle lifts, a welding and fabrication shop, Dynojet 248C chassis dynamometer rated to 1800 rear wheel horsepower, Dyno Dynamics all-wheel drive chassis dynamometer rated to 2000 horsepower, and a Hunter 4-wheel laser alignment rack built in-ground to handle lowered vehicles and race cars.

The surrounding acreage includes a ¼-mile drag strip and 1.4-mile road course to allow testing and development to be done on site.

Hennessey Performance also operates a state certified Tuner School on the premises offering hands-on instruction to students interested in pursuing a career in aftermarket performance tuning. The school has also provided Hennessey with some of its own in-house technicians.

Hennessey Performance continues to grow. A new 10,000-square foot production and service facility in Southern California opens in July 2011. The Lake Forest, CA location is midway between Los Angeles and San Diego and will serve customers west of the Rockies.

After two decades, while the size and scope of the operations, along with the vehicles and products, have diversified and expanded, the founding principle of Hennessey Performance has remained unchanged. The goal is to provide ultimate performance for customers, who like partners John Hennessey and Don Goldman, have a passion for speed and racing.

Hennessey History

1991
John Hennessey purchases new Mitsubishi 3000GT vr4 to pursue his dream of entering the Pikes Peak Hill Climb. After developing his own modifications to the exhaust and turbochargers for added power, he prepares for the July 4th hill climb by entering the Nevada Open Road Challenge in May. With no prior experience, he finishes fourth overall averaging 164 mph over the 90-mile course in a car he had driven to Ely, Nevada and back from Houston. He also drove his car, loaded with tools and spares, to Colorado and back in July when he successfully completed his run in the Pikes Peak Hill Climb. In August, he again drove, not trailered, his car to the Bonneville Salt Flats where he set a class record of 177 mph. And, to finish up his whirlwind tour of high-speed endeavors, that November he returned to Nevada for the Silver State Challenge open road race where he was the overall winner with an average speed of 177 mph.

In between races, he also found time, on October 12, to marry his fiancé Hope. With her support, John gave up his successful environmental remediation business and aimed his entrepreneurial skills at turning his passion for high performance and racing into his life's work by founding Hennessey Performance Engineering.

1992
Working out of a rented garage with a single technician, John specialized in offering modified turbochargers and intake/exhaust systems for the Mitsubishi 3000 GT and its Dodge Stealth sibling as well as other turbocharged imports such as the Toyota Supra and Mazda RX7.
Hennessey Performance gets its initial media exposure with an article in Car & Driver recounting his racing exploits and the modifications he made to his Mitsubishi 3000 GT, which he dubbed the vr200.

1993
The first Viper Venom 500 was built for a customer interested in competing in Nevada open road races. In May, the car won its class and finished fourth overall with an average of 164 mph at the Nevada Open Road Challenge. Being one of the first, if not the first, Viper entered in any competition, it was featured in Car & Driver, Motor Trend, Hot Rod and Car Craft.

1994
The Viper Venom 550 debuts with a 50 horsepower increase over the Venom 500 thanks to HPE's design of the world's first Viper 5-to-1 tubular headers and development of high performance valve train improvements in conjunction with Competition Cams. Motor Trend track tests a Venom 500 and Venom 550 with both cars entering the magazine's rather exclusive for the time '3-second club' by posting 0 to 60 mph runs of 3.7 and 3.5 seconds respectively.
Hennessey Performance is involved in development and sales of the first hardtop
designed for the Viper.
A Belgian team enters two Vipers at the 24 Hours of Le Mans utilizing exhaust headers, valve train components and other racing parts from Hennessey Performance. One of the team's Vipers finishes an incredible tenth overall. 1995 John Hennessey becomes one of the founding members of the Viper Club of America.
Venom 600, featuring a stroker kit with custom crank, debuts at Motor Trend shootout held at Firebird Raceway. It decisively beats the competition to earn 'cover shot' status.
An earlier experience at a Road & Track top speed event did not result in a victory but brought home the lesson of having world-class test equipment. HPE purchases one of the first Dyno Jet rolling chassis dynamometers.

1996
Viper GTS debuts and HPE improves stroker kit to produce 650 horsepower resulting in the 650r model.

1997
John Hennessey pilots a 650r around the tricky high-speed oval at the Honda proving grounds in Arizona to become the first Viper to hit 200 mph with a speed of 203 mph. Motor Trend features the record run with a cover story.

1998
John drives his personal Viper GTS to establish a new speed record for the Elko Twin 50 open road race with an average of 177 mph on the return run.
With the arrival of his and Hope's fifth child, John Hennessey puts his family's interest first by retiring from high speed racing events, limiting himself to drag strip and road course testing.

1999
Venom 800 debuts. It is the result of John Hennessey's decision that the time is right to develop a twin turbo Viper V10. He sets a goal of 200 mph in the standing mile. With 700 horsepower to the rear wheels, the Venom 800 comes up slightly shy of the mark with a speed of 197 mph, but does become the first tuner car tested by Motor Trend to do 0 to 60 in 2.9 seconds and the ¼-mile in 9.9 seconds.

2000 to 2003
Development continues on the Viper. The 1000 horsepower Venom 1000 debuts and a 650r does 0 to 60 mph in 2.9 seconds and a 10.7 ¼-mile on street tires.
HPE grows from five employees in 1995 to a dozen.

2004
Acquisition of the Lonestar Motorsports complex including 1/8-mile drag strip.
Venom 800 Twin Turbo SRT-10 captures overall win over 16 tuner cars in Car & Driver Supercar Challenge. The two-day event includes one day of road testing by the editors followed by a day on the oval and infield road course of Michigan International Speedway testing braking, handling, and various levels of acceleration.

2005
In a Road & Track standing mile test on the runway at Lemoore Naval Air Station, the Hennessey Venom 1000 SRT-10 convertible posts the fastest top speed of 210.2 mph. The diverse field of 15 entrants includes a Saleen S7 and three racecars. The Venom 1000 is 7 mph faster than the Lola-Ford Cosworth Indy Car of Paul Gentilozzi. In a separate run over a longer distance to determine its maximum top speed, this Viper convertible hit 223 mph.
Don Goldman becomes associated with HPE, initially as a customer then a partner with John Hennessey in terms of developing the Lonestar Motorsports property. The drag strip is extended to a fully operational ¼-mile plus shutdown area and return road allowing it to be used for testing and development.

2007
In a Road & Track 0 to 200 mph shootout at Lemoore Naval Air Station between six of the world's fastest super cars, the 1100-hp Venom 1000 coupe is the winner with a time of 20.3 seconds, nearly a full four seconds quicker than the runner up Bugatti Veyron 16.4.
John Hennessey shifts his thinking from increasing horsepower to reducing weight to achieve a comfortable, user-friendly 200 mph road car. He commissions a designer in the UK to create plans for a car based on a Lotus Elise with a Viper V10 amidships that is the precursor to the Venom GT.
In December, ground is broken for building the company's new facilities adjacent to Lonestar Motorsports Park.

2008
HPE Ford GT 1000 Twin Turbo becomes the world's fastest Ford GT at the time with a 234 mph run at Lemoore NAS.
HPE moves into its new home, a 30,000-square-foot building adjacent to Lonestar Motorsports Park, off Interstate 10, about 45 minutes west of Houston.
Tuner School, first school dedicated to teaching and training high performance vehicle tuners opens within the new facilities.
Hennessey establishes YouTube channel to post entertaining and informative videos of its vehicles in action.

2009
HPE expands into General Motors tuning with Cadillac CTS V and Corvette ZR1 leading the way.
HPE 700 LS9 Camaro debuts with 691-hp at the rear wheels. The car is an immediate hit establishing HPE among Chevrolet performance customers.
Venom GT development continues in the UK with Chevrolet LS9 V8 replacing the twin turbo Viper V10 of the original concept.
Don Goldman becomes a partner in HPE bringing in operational and systems skills that allow John Hennessey to refocus on product development and sales.

2010
SoCal shop opens in Lake Forest, CA
Venom GT prototype debuts and is followed later in the year by delivery of the first production version.
Top Gear devotes cover story to Venom GT.
HPE dealer network continues to expand for ordering cars through Chevrolet, Dodge, and Ford dealers across the country. New website is launched.

2011
Happy 20th anniversary to John and Hope Hennessey as well as HPE. Over the last two decades both the couple and the company have reason to celebrate as the couple has expanded to a family of five children while HPE business family has grown to 30 employees.
Venom GT appears on cover of Road & Track
HPE West Coast operations move into new 10,000-square foot production and service facility located in Lake Forest, CA in August to service customers west of the Rockies.

          uhhh... has not happened since? You mean like in 2009/2010 when HPE purchased off the shelf HKS 570 kits for the R35 GTR, re-branded them HPE kits, and marked them up 100%+? Hell they even used HKS's photo's in the advertising with slightly faded HKS water marks! More of the HPE norm.. Purchase (or sometimes make, but rarely) 10k worth of mods, give the package a name, slap a sticker on it, somehow get it reviewed by magazines and sell it for 50k...

          If I'm John Hennessey, why would I be talking about Evolution Performance? HPE tunes Mustangs, also. So that would mean a conflict of interest if I was him, right? By the way, neither of those accounts that were banned from other websites were EVER proven to be John Hennessey, and numerous people who personally know him have said that that wasn't like him to personally attack people like he did on that 300C forum.

          Fine post gadflyjczc -- the proof is in the pudding. Go look at the Viper forums -- just a whole lot more proof of what a crook Hennessey is. What do you have to say now, Elmo? You keep claiming that you're not John Hennessey. You're either John or his lover... One or the other but nothing else.

          Uh all that turned up on the thread was people claiming it was a photoshopped picture, even one person saying that they found it fishy that the same picture wasn't even on Hennessey's website and posted by some person not even relating to Hennessey. There's no post on that thread that says that he uses HKS parts, only that it was an HKS picture. From this link: http://www.hennesseyperformance.com/gtr-performance-parts.html It is showing they are a retailer of GT-R parts and accessories. It's also clear that they are not claiming those parts as their own with the HKS logo at the bottom of the pictures. Here's some more evidence of that: http://www.hennesseyperformance.com/gtr-air-turbo.html HPE IS A TUNER. They aren't a manufacturer of performance products. There are bunches of other tuners out there that use products that they don't manufacture.

          The only GT-R issue I have heard of was the sheet metal screws being used to fasten in an MAF on 1 GT-R, and that employee was fired shortly after. I can't find anything on what you're talking about. Mind showing me proof?

          @Elmo
          His 600 kit was an HKS gt 570 kit, paired with a Cobb access port, and a Chinese made knock off exhaust. Where is the tuning in that? Anyone can take other tuners parts and slap them on a car... I am not going to aurgue with you. I have no idea why you are swinging off John's nuts so bad... I have met John several times, and I don't think he is a bad guy. Yes he got in a bind a while back, he made a big mistake. I get that. Even good people do desperate things in desperate situations. My point is that John's products are normally not his, and he charges crazy money for what you get. Nothing to do with John personally, just feel like he does very little for how much money he charges.

          AB needs to kick John Hennessey (aka "Elmo") off this forum as he has been banned from other forums. This is getting ridiculous... John is a hack so stop calling him a tuner. Folks like Callaway, Lingenfelter and Heffner are tuners. I've dealt with two of the three -- I know.

          Sure... here is your proof. This the the thread on NAGTROC.com that busted him on it. Both his packages were nothing but off the shelf HKS performance packages that he marked up @100%, and in the second pictures of his ad, (in the upper right) you can clearly see the faded HKS watermark where he just used HKS images. http://www.nagtroc.org/forums/index.php?showtopic=27209&hl=hks+watermark

          HKS isn't a tuner, they are an aftermarket product retailer and manufacturer. So just because they used someone else's products, it doesn't mean they're a tuner? They tuned the car to their specifications. Like I said, a lot of other tuners use other aftermarket manufacturer's products. If I remember correctly, Evolution Performance (semi-large Mustang tuner, although very well known in the Mustang community) uses SCT Tuners, not their own. They also built a 9 second 2011 Mustang GT from parts purchased off of AmericanMuscle.com.

          @mostchillininsc
          Funny how you talk about proving me wrong when not once did you show me proof of you commenting on non-Hennessey articles before this article. By the way, the whole thing about you inviting me to fight you because of a tiny little argument on the internet is pathetic. No, I'm not scared. I just realize that, once again, I have encountered yet another pot calling the kettle black. You just accused me of coming onto these articles just so I can flex my muscles. But look at what you're doing by inviting me to your house just so you can fight me because I used the word "retard". What would you call that? Oh yeah, that's right. That's called flexing your muscles. Like I've said in the past, it's people like you who ruin this country. People who cry over the smallest of jokes involving the word "retard" when it isn't even directed at people with mental and physical disabilities. THAT is the reason you keep coming back to these articles. You're angry over the fact that I used "retard", so you need to "flex your muscles" in order to look like the "bigger man" in the situation. It has absolutely nothing to do with Hennessey, his past, or what he's been accused of. I can see straight through you. I worked with people with both mental and physical disabilities for 6 straight years of my life. Do you really think after all those years of doing something that I absolutely love (yes, love as I still would LOVE to do that type of work again because I love making them happy), that I would direct the word "retard" at someone with a mental or physical disability? So to conclude... Shut the hell up and get the hell off my nuts, you pathetic waste of space.

      I think this is the best looking version of this McLaren I've seen. It adds just the right amount of aggression. They added some interest along the sides with the subtle changes but they didn't really ruin anything. I'm a little shocked at how much I like the look, these aftermarket tuners usually go too far for me. I'm still not sure I'd purchase from this guy... I'd probably wait until I had a great lawyer to threaten/sue him if required.

      I don't think the car needs much improvement, and if any are made I would much prefer them to be implemented directly by McLaren in future models, not by some Texas drag racer. Incidentally compare McLaren's facilities in the UK to Hennessey's in TX. A Norman Foster masterpiece next to a corrugated steel eyesore. Compare McLaren's F1 track record to Hennessey's lack thereof. He can't improve upon the suspension because he hasn't the expertise to do so. He may get more power from the engine but he will ruin it in the process. I can only imagine what his crudely pieced together 'enhancements' do to the service life and resale value of the victims. It may be more appropriate for the man's station to stick to ponycars. With a McLaren he's more than a little bit out of his league.

      I hope this hack keeps his grubby mits off perfection. ham-fisted egotist puts out press releases associating himself with greatness just so he can pretend to be in the same league

        he pays for some renderings, figures out on paper how he could make it have higher output (and less reliability) - then puts out a press release. and AB bites......what a joke

          Less reliability? So why hasn't the Hennessey Venom GT had any reported problems?

      not me cup o tea; John Hennessey leaves a bad taste in customer's mouths, he is a bad dude..

      Anyone bets none of them dyno over 600whp and the 850 is derrived from using massively inflated "driveline losses" to cover up that a couple of cone filters from china and a bit more boost isn't going to make 250 more HP.

      He is not upgrading the suspension because it is too complex a system for him to understand. what? no roll bars to make fatter....?! then what do I do?!

        Doesn't the MP4-12C use some type of magnetic rid suspension technology? If so, then he's already messed with in the CTS-V. By the way, it's not that hard to swap out the complex system with coil suspension. I've already seen quite a few people do it on their CTS-Vs.

      So why to this date does AB still think it's great to post news about HPE?

        Because there's no new cars on Jay Leno's Garage of course!
