No matter where you like your power, Ford builds a Mustang for you. Some of us like to shift above 8,500 rpm, and the GT350 is the first American car to offer a flat-plane V8. With the ability to rev beyond anything else, why not make use of that high rpm to spin a pair of turbos? John Hennessey and his team have already developed two flavors of the GT350. The first is able to make 575 horsepower and 511 lb-ft of torque without adding boost. Next up is the HPE850. It uses a 2.9-liter supercharger at 6 lbs of boost to make 858 horsepower and 673 lb-ft of torque. [soliloquy id="118931"] The only problem with superchargers is that they are great for conventional V8 engines. That is ones that reach max power below 7,000 rpm. They are spun by an engine belt, at a fixed ratio from the crankshaft. He explained this when I drove his HPE1200 Ford GT at the Orange County Auto Show back in 2012. Unless you have a top-fueled dragster, a supercharger is best suited for low-rpm (under 7,000 rpm) boost.
