now the question is... can the stock fuel system deliver enough fuel to run e85. if so, we are in for interesting times.
thats how i tuned by WRX, uses cobb access port and access tuner race, i run e85 or 93 oct gas. with e85, i get 300whp on a conservative tune running a slightly bigger bolt on turbo, cobb turbo back, slightly bigger top mount. all of the work done buy me. since the turbo, turbo back and top mount were all simple bolt ons, it was pretty easy to do and provides a significant power increase on a stock, unmodified motor.

That is very quick for such a tiny little FWD car. Awesome work!

I don't get it, almost everyone else says the stock intercooler is pretty good for what it is. But ATP says they quickly ran into problems with the factory unit.

I think you are missing the fact that ATP is using/testing a different turbo with more output.

It looks like ATP has kept tuning their car.
They have two new YouTube videos, the GT turbo running a 13.1 and beating a bunch of Hondas and a GTX turbo running 12.9 @106.
I think the turbos used are GT25 something and GTX2860 or something.
They have a new set of race wheels on the front and it sounds like a launch control in the Cobb tune.
I bet they haven't found all the speed in either combo so the smaller GT turbo upgrade is probably good for high 12s and the GTX is probably good for mid-low 12s, maybe even 11s.
That kind of speed is going to surprise a lot of people.
One time a 458 thought I was trying to race him (I wasn't), he floors it and as I thought "this should be interesting", I floored it too. He walked me but nowhere near as bad as I was expecting and I didn't even shift out of 6'th gear. If I down shift and have enough power to run 13 flat, a 458 would just barely walk away and trust me, when a Ferrari driver can barely walk a Fiesta, they are going to be pissed.

I read someone post yesterday where they said what happens at higher boost levels is that you need better flow, not better cooling. The stock intercooler does a great job but flows like crap, flowing like crap means the air stays in longer which means it cools more, but you'll be restricted by flow not necessarily temperature at higher boost levels.
Also every aftermarket tuner has released an intercooler for their packages, Mountune, Cobb (soon), FSwerks, puma speed, etc. While we can be cynical and say they are just doing it to make money, I have faith that these tuners know what they're doing and are giving us parts that will help performance.

Here's the link to the video where they're running 12.9

Any air-air intercooler is a compromise, some are just better than others.
Ford gave us a nice big space but the core is physically long so the path is restrictive and the core is not the absolute most efficient out there.
The improved cores are thicker for less restriction but its like breathing through 15 coffee stirrers instead of 10. The cores are more efficient also.
I was just looking for EcoBoost 1.5 intercooler pics. That one is an air-water intercooler which exploits the greater specific heat of water to make a smaller core with less restriction that can suck out more heat than air-air. Of course they need a separate water-air intercooler with a pump to circulate water but you can go big on that without adding any intake restriction.
An interesting solution is the intercooler from Levels. Its wide but they shortened it. That's good for reducing restriction but you have to make sure you have enough core which might not be true at higher power.

I'll agree but its a minor contributor.
When stuff like a Squire STS pretty much works as goofy as it seems, you realize that a thicker intercooler core or an extra foot of cold side plumbing are not going to have a meaningful effect on lag.
The ATP or Cobb plumbing will spool pretty much like stock if you keep the stock turbo.

Kinda puts the intake purchase to rest for me. Just got an email response from ATP as i wondered what intake they were using if any and hitting +300hp.
They said they are using the OE air box w/ just a drop in filter.
Pretty much proves the efficiency of the stock system. So HP wise, we are pretty good sticking w/ the stock box or the mountune design. Ofcourse they dont provide whooooooosh noises but definately do the job well.

Yup, that sure isnt the stock box!
This is the exact quote, " within current test and development phase we utilized the stock intake system and a performance filter. To date all performance modification dyno pulls, track results and road tests utilize stock intake system and performance filter. In the event we experience possible restrictive systems, we will test alternatives. So far no issues"
But, in reality sticking an open filter down by the road like that *probably* doesnt pull much if any more air than the mountune box with its two air inlets.
The surface area of the oe filter size is already about 7x that of even the mountune highflow intake tube. So, there is lots of air coming in.... Getting it through the test of the system at high enough velocity seems to be the issue to make HP
