2014 F150 Ecoboost Review
I guess you could call me a truck and car enthusiast and I really enjoy driving different ones and comparing. I always thought I'd buy a car when my truck is paid off, using the truck strictly for tow...

There are lots of reasons just outed for the designers choices
Many have commented on the smallish turbines...spooling up to reduce lag seems
to be the reason...with them topping out on the upper end...but this is a small
displacement...so that makes sense
The dew point issue with the inter-cooler affects in all RPM ranges, but at the
higher boost of higher rev's the temp differential will be greater...therefore
higher chances of dew point issues
Boy racers for decades have known about this dew point issue and many approaches
that have worked for decades. The tiny drain hole...has potential to whistle if
not done right...and as usual, an OEM with tons of money has designed a much
more elaborate drain. Also putting the cold side tube on the high side avoids
most of the H2O issues, as the dew point is in the cooling tube area and will
drain 'down' into the plenum on the bottom...why the cold plenum should be on
the high side. FPS/CFM does affect the H2O flow
Everything the OP has observed is typical of lag and the boy racer trick is to
throttle/brake up to stall before launching...but that is tough, tough, tough
on the drive train and torque management kicks in
Oxymoron wanting that high power AND high MPG. Gotta stay off high throttle
settings of you want high MPG and let the small displacement continue to be
small displacement. With forced induction...that small displacement becomes an
'apparent' bigger displacement in a small displacement CC
It is an end all, or seemingly, to those who don't have much experience
with forced induction...can't wait till they discover nitrious... :B
