Strong Rumor: 2015 Mustang Engine Lineup Leaked, Includes 475 hp 5.0 Coyote
http://www.stangtv.com/features/car-...es-475-hp-5-0/
"The final rumored engine according to the source would be a slightly revised 5.0 Coyote. Firing yet another salvo in the ponycar wars, the S550 Mustang GT would be carrying a big stick and running a
475 hp version of the popular 302. It’s hard to say exactly how Ford will achieve
475 hp. We would speculate the use of direct injection would help with this since the cylinder heads are already cast with direct injection in mind. Adding DI could allow for more power in the form of either a higher compression ratio, or more aggressive cam profiles, and timing. It may also open the door to further improvements in intake manifold design, and even a cylinder shut down system for cruising, improving fuel economy and emissions while allowing for V8 power on demand. No doubt the engineers have found a way to boost power and ensure the 2015 Mustang debuts as king-of-the-muscelcar-hill."
