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.
“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!”
