HEAVY work underway at Full-Race (EFR ecoboost upgrade)
If you guys have facebook, check Full-Race's page. They are giving updates on their turbo upgrade for the EB. Nothing crazy yet, but they have been prepping manifolds for the EFR turbos.

Part 2 of our EcoBoost F150 article posted Online HERE: http://www.full-race.com/articles/inside-the-ecoboost-f-150.html
Happy to help. Even not being a hotrodder, these motors are detuned from the factory. A tune can help, but it is equally or more important to do a basic exhaust and air filter upgrade. This should be considered mandatory when modding!! The stock EB exhaust has 7.5psi backpressure post turbine - that is CRAZY high. Going to a 3" exhaust alone is the way to go for these engines (any larger does nothing but rasp and drone, sound like an unhealthy honda)
note: I am not a fan of aftermarket intakes, instead i prefer drop-in replacement filters into the OEM airbox (like the AEM)
... just the beginning
starting with our exhaust and intercooler (release in november after SEMA) the turbokit will not be far behind!
our primary turbo kit is designed to make big TQ #s. However that same kit can support the large Borg Warner EFR turbos... so 10sec timeslips in an EB F150 is totally possible.
the blocks have different mounting bosses cast in... unless you plan to do some major surgery and/or swap internals you might be disappointed. I see you are in phoenix, if you wanted to stop by in about 2 weeks i have some EB motors on engine stands i can show you
glad you liked matchbot, very cool program. you can input your altitude into it and get a good idea of how the system will behave. is 700+ft lb and 500hp possible on stock motor?? matchbot says it is... we will find out for certain

Correct me if I'm wrong, I believe the limiting power of the eco is the fuel system, not the turbos. I believe it's the tuners themselves that are saying this which mean upgrading the turbos will probably be marginal gains, possibly offest by a loss in the low end.
My point being if I had an eco I would want to see some fuel system parts in that picture.

The trade-off is spool time, as you suggested.

Increasing the size of turbos affects power in a lot of ways, not all of which require more fuel. You'll get a bigger compressor that runs at a more efficient place on its map. Typically, OEM turbos are sized smaller than peak efficiency to improve spoolup. Running a bigger compressor in a more efficient zone reduces the shaft hp required to spin the compressor. This allows the turbine to not work as hard, leading to the wastegate bypassing more exhaust, thus reducing exhaust/drive pressure. Furthermore, the larger exhaust wheel will flow more mass for a given pressure. This, again, reduces exhaust pressure. All these reductions in exhaust pressure reduces pumping losses during the exhaust stroke. Keep in mind that typical turbo exhaust pressure can be as high as 50 psi (this is the turbo's equivalent to "parasitic drag"). Dropping this to 30 psi will greatly improve hp without requiring more fuel. All this is accomplished at the same boost level, too, so engine safety and longevity is also improved.

Rick.....call those guys and talk them into tuning through Livernois.
