Hennessey Performance Engineering set its sights on modifying one of the finer Ferrari models.
The Hennessey HPE700 Twin Turbo upgrades release enough power to boost the mid-mounted 4.5 litre V8 engine up to 738 hp at 8,400 rpm and 532 lb-ft of torque at 5,600 rpm. The extra 170 crankshaft horsepower pushes performance to a whole new level. 60 mph pops up at 2.8 seconds with a quarter-mile time of 10.5 seconds at 137 mph.
Low-inertia ball-bearing turbochargers are used to boost the power, and an air-to-water intercooler makes sure the air surging into the combustion chambers is as cool and dense as possible. Twin wastegates and blow-off valves relieve extra boost pressure and, in addition to a new stainless-steel exhaust system, add some new noises to the 458’s soundtrack.
The V8 is boosted to a relatively mild 7 psi maximum and maintains 6 psi on its way up to redline. A reflash of the engine control unit brings the package together, reports the Autoblog.
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.
The Ferrari 458 HPE700 Twin Turbo upgrade is on offer for $59,995 installed. Perhaps the best part is the fact that it includes a 1-year/12,000-mile limited warranty alongside full dyno tuning and road testing.
Hennessey Performance haven’t fitted any visual upgrades to the show car aside from the badging. A carbon fibre front splitter and rear lip spoiler are in the works. A set of Hennessey 20 inch monoblock forged wheels are available and fitted to the show car with a set of standard Ferrari centre caps.
A KW suspension system is available as are interior enhancements. 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.
Meanwhile a lurid taste of what the HPE700 is like to drive can be found on the Hennessey site, courtesy of communications manager Doug Knott. He says, “Before the Hennessey update, the Ferrari’s 4.5-liter V-8 was angry; now it’s just flat p*ssed off and looking to vent its full fury on some innocent stretch of road.”
Hennessey Performance 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!”
“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.”
