Hennessey Performance Promises to Turn McLaren MP4-12C into an 800HP Beast

If there's one thing the stock McLaren MP4-12C has in abundance it's power from the mid-mounted 3.8-liter twin-turbocharged V8 engine which is rated at 600PS (592HP) and 600Nm (442.5 lb-ft).

However, Texas-based tuning firm Hennessey Performance begs to differ as it believes the MP4-12C could do with some additional horses under the hood – 200 of them, to be precise.

Bulgarian Design Studio Vilner Revisits Jeep Grand Cherokee SRT600

The Hennessey-prepped Jeep Grand Cherokee SRT600 is once again in the center of attention of the Bulgarian design firm Vilner. Back in October 2010, the company had launched its first take on the Hennessey Grand Cherokee SRT600 that packs a modified V8 engine fitted with a "Vortech" turbo system for an output of 600-horses.

Video: Guess What Scared a 1,200 HP Bugatti Veyron Super Sport at Goodwood…

There’s nothing faster, short of a Formula 1 car, than a Bugatti Veyron, right? In particular, a Bugatti Veyron Super Sport boasting a 1,200HP quad-turbocharged 16-cylinder engine, four-wheel drive tech and a 258 mph (415 km/h) top speed. Whoever is behind its wheel must feel invincible, right?

Hennessey’s Tire-Shredding HPE500 Supercharged Ram Truck on Film

The tuners over at Hennessey Performance have always had a thing for boosting anything that rides on four wheels. More recently, the Texas-based tuning firm applied its technical wizardry on the Ram Truck. The result is the Hennessey HPE500 Supercharged Ram, which as implied by its name, features a supercharged version of the Chrysler Group’s 5.7-liter Hemi V8 producing 505-horsepower at 5,400 rpm.

The tune include numerous standard upgrades such as a sport exhaust and Hennessey embroidered seats, along with various optional parts like different alloy wheel and tire combos and suspension systems. While we’re waiting for Hennessey to pit the HPE500 Supercharged Ram against a stock Nissan GT-R or a Porsche 911 Turbo, you can watch the powerful pickup truck in some tire shredding action in the video after the break.

Hennessey's HPE1000 Escalade Cracks 60 in 3.3 Sec, bests Nissan's GT-R [with Video]

The concept of turning SUVs into pavement-pounding, drag-racing, supercar-shredding monster rods never ceases to amaze me, and by that I mean my jaw is on the floor and I'm completely boggled. I love me some automobiles (and vehicular transportation in general), but there's something about a nigh-three ton box on wheels and oodles of GO that seems...weird.

However, if monster rods - or high performance in general - are your cup of Starbucks soy latte, then Hennessey has got you covered (as if you didn't know that already, what with their cray-cray 1,000+ horsepower Vipers from way back when). Below, for your viewing pleasure, is video of a 2011 Cadillac Escalade drag racing a 2011 R35 GT-R and beating it.

VIDEO: Hennessey’s Cadillac CTS-V Sport Wagon vs Nissan GT-R and Porsche 911 Turbo

American tuning firm Hennessey has crafted some pretty insane vehicles over the years. One of its most recent tunes is based on the Cadillac CTS-V Sport Wagon, which leaves GM’s factory with a 556-horsepower 6.2-liter V8 lump, but once Hennessey’s engineers perform their magic under the hood, output is lifted to 650 horsepower.

To show off the tuned CTS-V Sport Wagon’s potential, the Texas-based company brought the Cadillac to the track and drag raced it first against a stock 480HP Porsche 911 Turbo [997] and then a standard 485HP 2011 Nissan GT-R. Watch what happened in the video after the jump.

The Hyundai Genesis Coupe appears to be gathering the attention of tuners at this year's SEMA Show. For this particular proposal, Hyundai Motor America teamed up with Hennessey Performance Engineering (HPE) and the firm's Tuner School.

Hennessey’s 725 Hp & 190 MPH Turbocharged Dodge Challenger SRT700

It was only a matter of time before we started seeing tuning propositions for Dodge’s highly anticipated Challenger Coupe. Hennessey Performance, which is widely known for their Dodge Viper conversions, is offering a unique power kit for the Challenger SRT8 that will be available for a mere 25 clients in 2008.

The result is a maximum output of 725 Hp at 5,200 rpm and 1,016Nm (750lb-ft) of torque at 4,000 rpm compared to the standard V8’s 425 HP and 420 lb.-ft. of torque. According to Hennessey, the supped up Challenger SRT700 Turbo can go from zero to 60 mph (96 km/h) in approx 3.5 sec, hit the quarter mile in 11.3 sec at 126 mph or 203 km/h and reach a top speed of 190 mph or 305 km/h.
