Where does the 2013 GT 5.0 get the extra 8 horsepower?

The current 11-12 GT owners seem to be upset that the new model is getting a modest 8hp bump lol at least you don't have the buyers remorse that 2010 GT owners got when the 2011 came out.
no marketing department would be so dumb as to not have made that VERY well known. We wouldn't be guessing. BTW, power ratings are whatever the manufacturer says they are. People just get unhappy if the real output is lower than what is claimed.

I am thrilled with the stock motor in my car. Another 8hp would be welcome, of course but probably not even noticable.
It's the 2015 motor that I'm curious about. I'm predicting the appearance of the direct injection (finally) and forged internals for everybody.

I for one hope not to see direct injection.

There are legitimate worried about DI on gasoline motors...but when it works right, there is a really impressive improvement in power and efficiency. I have faith that Ford could pull it off.
Regardless, the forged internals would be amazing.

I would be more concerned about high pressure gasoline leaks and high pressure injector pumps.
I disagree. You can add FI to a DI motor, but there are a number of things to consider. Seems like the gains aren't anywhere near as good on DI as it is on PI. Also, almost every DI turbo motor I've seen has some "plateau" that they reach with power levels that is a major pain to break through.

How so? At the OEM level, it does not. At the aftermarket level it poses a new set of issues that need to be addressed when power levels reach those levels. All it's going to do is set the aftermarket back until they get past that plateau, and it can be done.
I don't understand how turbo/SC is out of the question on a DI motor. BMW, Audi, Mazda, Ford, GM, etc. already have versions of smaller motors running that exact setup. Granted, most are turbo applications, but a SC should perform similarly, but generate a more linear torque curve. Ford's EcoBoost motors are all DI turbo applications.
