Hennessey Performance (HPE) will unveil the company’s first modified Ferrari tomorrow 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 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 728bhp (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 the 458 to an even higher performance plateau, with an added raw soundtrack to match its explosive quarter-mile time: 10.5 seconds at 137 mph. It’s an elite 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-fibre 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 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-litre V-8’s 9000-rpm redline. A Hennessey reflash of the engine-control computer works in concert with the Ferrari’s direct injection to optimise fuel delivery and spark.
Further styling upgrades include Hennessey 20-in. monoblock forged wheels, a KW suspension system with 2-way adjustable shocks and threaded spring perches for easy corner weighting and ride-height adjustment.
