Here's an article on Edmunds for the 2010 Mustang stating an engine option of a 3.5L v6 with twin turbos. Yes, twin turbos. It will probably make production. Imagine stuffing that in you MAVCOM. 300 HP. http://www.edmunds.com:80/ford/mustang/2010/review.html
with all the new CAFE regulations i wouldnt be suprised if hipo/FI v6s became the top of the food chain for modern american muscle cars it'll be like the 1980s all over again lol
