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.

Hennessey Performance (HPE) will unveil the company’s first modified Ferrari on Friday, August 16th at Concorso Italiano, a display of Italian machinery that’s part of the annual celebration of classic and historic cars informally known as the Monterey Weekend. The car will be shown at Concorso’s home, the Laguna Seca Golf Ranch off Highway 68, in conjunction with Meguiar’s, a maker of premium car care products. On Saturday, August 17th, the car will be on display in Laguna Seca’s paddock as part of the Rolex Monterey Motorsports Reunion.

“The HPE700 Twin Turbo 458 delivers a sound and driving experience that few road cars can offer,” said company founder John Hennessey. “Aventador owners, beware—this car will take you by surprise!”

The Hennessey HPE700 Twin Turbo upgrade for the Ferrari 458 delivers 738 horsepower at 8,400 rpm and 532 lb-ft of torque at 5,600 rpm. The additional thrust, approximately 170 more crankshaft horsepower than stock, pushes this already magnificent steed from Maranello to an even higher performance plateau, with a compelling, raw soundtrack to match its explosive quarter-mile time: 10.5 seconds at 137 mph. It’s a rarefied group of supercars that can sprint to 60 mph in under 3.0 seconds, and the HPE700 Twin Turbo Ferrari easily qualifies at 2.8.

Most of the upgrade’s componentry is concealed beneath custom-made carbon-fiber covers, but if you stripped them away you’d see the low-inertia ball-bearing turbochargers tucked up neatly toward the tail end of the dual-clutch sequential 7-speed gearbox, the TIG-welded, mandrel-bent T304 stainless tubing, the twin wastegates and blow-off valves and an especially trick aluminum plenum that contains the air-to-water charge-cooler element. At the other end of the self-contained charge-cooling loop is a rear-mounted heat exchanger, paired with dual electric fans that work to reduce inlet temperatures that come with a maximum boost pressure of 7 psi, and holding 6 psi through the 4.5-liter V-8’s 9000-rpm redline. A Hennessey reflash of the engine-control computer works in concert with the Ferrari’s direct injection to optimize fuel delivery and spark. Overall, it’s an elegantly engineered system, finished to Ferrari standards and expertly packaged in the 458’s tight hindquarters.

Further personalization will be possible with optional upgrades including Hennessey’s CarbonAero exterior pieces (currently under development) consisting of a carbon-fiber front splitter and rear lip spoiler designed to accentuate the 458’s seductive lines. Hennessey 20-in. monoblock forged wheels are available, as is a KW suspension system with 2-way adjustable shocks and threaded spring perches for easy corner weighting and ride-height adjustment. Interior upgrades can be as extensive as the buyer desires, with custom leather/Alcantara color combinations, special stitch patterns and carbon-fiber trim for the dash and instrument cluster.

The Ferrari 458’s HPE700 Twin Turbo upgrade includes a 1-year/12,000-mile limited warranty and full dyno tuning and road testing. Serial-numbered aluminum plaques for both the engine compartment and dash are part of the upgrade, as is Hennessey exterior badging.

“This car will impress any Ferrari owner,” said Don Goldman, HPE CEO and longtime Ferrari owner. “Most purists would shudder at the thought of modifying their Ferrari. However, the HPE700 Twin Turbo 458 would easily change their mind.”
