Direct Injection = no aftermarket support. It'll fade soon after release as the Ford's Ecoboost.
Fade? No aftermarket support? You sir are terribly mis-informed!
There are a number of high profile companies supporting the Ford and GM DI turbo'd motors!! Livornois Motorsports being at the top of the heap. There's already a large number of Ford Ecoboost Flex's and Tuarus SHO's run in the 12.7 and quicker range with nothing more than a LMS tune. The potential is tremendeous!
Keep in mind that average Flex tips the scales at over 4,800# with driver. Do the math yourself, how much horsepower does it take to get 4,800# down the track to the tune of a 12.7 @ 109+
Geez, even my MKT (bone stock) runs 14.7's. It, weighs 5,000# even before I get in!! That's new, bone stock GN kind of numbers.
Nope, DI is here to stay, and the aftermarket is already on board and hitting big numbers.
Oh, and BTW, Ecoboost has hardly faded away. The sales numbers are staggering! And I suspect that GM (even though they're 4 years behind) will enjoy the same success with their DI turbo'd motors.
I do worry a bit about why GM decided to put two small intercoolers up in the intake manifold on the V6 though. Heat soak is going to be massive there.
Ford has managed to package a massive front mount intercooler on their V6 Ecoboost setups which seems to be working out quite well.
