Well known tuner Hennessey has recently revealed an upgrade program based on the Ferrari 458 Italia / Spider with better output.
The tuner has installed twin ball bearing turbochargers and upgraded the fuel system along with an air-to-water intercooler system, stainless steel inlet piping, dual wastegates and engine management calibration. Other tweaks to the model include custom oil and transmission lines, stainless steel exhaust system and turbo downpipes.
With these changes the V8 4.5-liter engine is now able to increase the output to an impressive 738 HP (543 kW) at 8,400 rpm and 532 lb-ft (720 Nm) of torque at 5,600 rpm. The modified 458 Spider is now able to accelerate to 0-60 mph (0-96 kmph) run in just 2.8 seconds and can run the quarter mile in 10.5 seconds at 137 mph (220 kmph).
Additional upgrades that are available in the model include a carbon fiber exterior body kit, a KW adjustable suspension, monoblock wheels wrapped in Michelin Pilot Super Sport tires, along with leather and carbon interior upgrades.
The power kit comes with a cost of mind boggling 59,995 USD and also comes with a one-year / 12,000-mile limited warranty.
