Hennessey twin turbo Ford GT

Hennessey is perhaps more closely associated with Dodge Vipers to most people, but they also do work on Ford's late, great supercar, the Ford GT, too. What Hennessey does with the GT is sort of up to you. One option they can do is a swap, wherein the factory supercharger is removed and a pair of turbos are fitted. With additional modifications, that car can reach more than 235 mph.

If it strikes you as a sacrilegious thing to do to a rare factory-supercharged car, you can keep your blower and simply add the twin turbos as well. They call that one the Ford GT1000 for the metric tonne of horsepower it produces. It can squirt from 0-60 in 2.6 seconds and cover the quarter in 10.6 on its way past 240 mph. The company had one of each on hand at SEMA this year in front of the duPont Registry trailer.
