Legendary tuning outfit Hennessey Performance has unveiled its upgraded Ferrari 458 Italia Spider. The Texas-based company added two turbochargers, increasing the vehicle’s power output to 738 horsepower and 532 lb-ft of torque (vs. the 562 horsepower and 398 lb-ft of torque for the stock model). Additional essential stats: a 0 to 60 mph sprint time of 2.8 seconds and a quarter-mile time of 10.5 seconds at 137 mph. Some of the details of the upgrade componentry include the low-inertia ball-bearing turbochargers, located at the tail end of the dual-clutch sequential 7-speed gearbox, with TIG-welded, mandrel-bent T304 stainless tubing, twin wastegates and blow-off valves, and 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; these come with a maximum boost pressure of 7 psi and hold 6 psi through the 4.5-liter V-8’s 9000-rpm redline. Optional upgrades include Hennessey’s CarbonAero exterior pieces, consisting of a carbon-fiber front splitter and rear lip spoiler, Hennessey 20-inch monoblock forged wheels and a KW suspension system with 2-way adjustable shocks. The Ferrari 458’s HPE700 Twin Turbo upgrade is available for $59,995 installed and includes a 1-year/12,000-mile limited warranty, plus full dyno tuning and road testing.
