Just got the Feb. issue of Car and Driver, their supposed to be making Performance Pack 2.3 ecoboost that does 145mph, a base 2.3 ecoboost that does 121mph. There's a v6 at 121 mph and the v8 is at 155mph. The front and rear suspension have been reworked, the new v8 is claimed to be faster than the Boss 302. The PP sounds like enough to me!
The 2.3 is going to be 305+ hp, but they haven't decided on the number yet! This is from interviews with Fords top people.
