Ferrari 458 Twin Turbo by Hennessey Performance

Though anyone who doesn't think the Ferrari 458 is fast enough as is might have a screw or two lose, you can't fault them for wanting something bigger and badder. This modded Ferrari from Hennessey Performance has 738 hp at 8,400 rpm and features twin ball bearing turbochargers, stainless steel inlet piping, air-to-water intercooler system, HPE engine management calibration and many other bells and whistles only a true titan of the road would appreciate.
