Stock HP limits of various components

[EcoPowerParts]

Fuel system:?
Turbos:?
Short block:?
MAF:?
Transfer case:?
Transmission:?

As these cars are being built up I'm sure we'll start hitting the stock limits of the turbo and MAF quickly. We're lucky with this car to have full tuning almost out of the box. I had to deal with a piggyback on my Mazda Speed 6 and it cost me later to the tune of $10K in a new motor after a few short weeks of a 3076 turbo upgrade (gotta pay if you want to be bleeding edge). These motors looks like they're built much better than the Ford motors in the Speed6's, those were very fragile to say the least. I'd love to get to a high 12 second 1/4 mile vehicle with good reliability and not unbearable to maintain (Flex variant). Tune/water injection/intake looks like it should get me there but I also don't want to be breaking on a monthly basis. Lived with that on my 96 Impala with a 250 shot, BOOM goes the 4L60E every time I went to the track....

Much of this has been discussed in many other threads. YOU MAY WANT TO DO A SEARCH......:thankyou:

Simple answers... Fuel system is biggest roadblock... NEEDS HIGHER VOLUME D.I. PUMP.
You can go to a 3 Bar MAPv sensor... I have... and Max Turbo Boost, if you could use it... is around 22PSI.... Tranny is an unknown.... Short block seems fine.... Ford had issues when testing a 3.7 version of the EB engine. AWD also an unknown....

SHO may have temp issues.... Custom Radiator & 170 T-stat..... WORK!

See Darreli's low 12's! W/M a good investment for great times!:angelnot: Key to any good run in the EB vehicle is a great 60 ft time!

A good tune from Torrie or Livernois is good for around 60 HP... Other mods are icing on the CAKE!

Quick recipe for high 12's that seems to work for many members here is :
Livernois tune, CAI, exhaust, good tires and a cool night.
Cost including tires is about 3K$ and so far reliability hasn't been an issue.
I am at 13 flat at 108 with only the tune... with tires and CAI, I expect to reach the 12's too.
Good luck and keep us posted of your results.
Cheers!

As Bob said.....Search is your friend. All this has been discussed several times. No one really knows the "limits" of anything on the platform yet. Well...Torrie knows at least one limit but fails to share it with anyone.

There is no MAF, but a MAP (Manifold Absolute Pressure) the stock limit of that is 14.7 pounds of boost.

All you need for 12's is a good tune and good air...the car will be completely relieable with a good tune.

All of this may have been discussed in a ton of topics but wouldn't it be nice to have this in a single easy to find thread for people. The question marks were for me to go back and edit so that new ecoboost owners looking to mod can easily find this stuff instead of searching for hours through random topics and offshoots of threads.
If you don't want to compile data like this into an easily used resource that's fine with me.

I understand where you're coming from. The majority of that is unknown at the present time. The stock MAP sensor is a 2-bar and is good to 14.x psi of boost. The rest is yet to be determined.

Everything I have read on this very message board indicates that CAI and exhaust are nothing more than noisemakers on this car. Not sure about good tires, but I ran 13.2@105 with only a Livernois stage 3 93 octane tune in less than ideal weather with a not fully broken-in car. I'm quite sure that I'll break into the 12s this fall in cooler weather with some more miles on the odometer.
My 60ft times aren't great - between 1.9 and 2.0, but I can't blame the tires - wheelspin hasn't been a problem. The stock Goodyear F1s - which aren't my first choice in tires by a long shot - appear to be about as good as it gets in the correct 20" or even 19" size. Lighter wheels would probaby help, but the choice is light and questionable strength (ASA, Bremmer, etc.) or expensive and strong (Wedsport, etc.). I'm not ready to dump $3K into wheels alone (much less tires) and think there are more cost effective ways to shave a few tenths off my 1/4 mile time.

Besides, this car is in dire need of brakes more than anything. I'll drop a couple $K on a TCE brake package before spending another dime on straight line mods.

Mentioned earlier that with a 3 bar map you can go to 22psi...but are the turbo still efficient at that boost level? What turbo do they use on these. Just looking at them they look super tiny.
Also any mention using a map clamp to run more boost without the computer pulling timing etc? Just a thought. Suppose just to it the right way and get a 3 bar MAP...what about the TIP sensor though. Not sure if it's similar to SRT's. But to run more boost on SRT you need a 3 bar MAP and TIP sensor.

 

[EcoBrick Bob]

They are small - 1.5" intakes.... Big question is fitment of other bigger turbos. And... we need a higher volume DI fuel pump.

TIP sensor is already a 3-bar. The 2 bar or 3 bar MAPv sensor are mounted in the top of the intake manifold - drivers side. The 3 Bar MAPv is identical (same part #) as the 3 Bar TIP sensor, and is available from Torrie @ Fastpartsnetwork - for around $100.

The turbos are GT11's

My experience says that boost will vary from a TIP of 58-72. Max is around 60 MPH the way I am set up. Also, boost levels for me vary a great deal depending on temp & humidity. This is with a 3-Bar sensor, W/M & a KB BAP & tuned accordingly. The turbos could be more efficient, but they're better than the DI pump....

I turned a 13.104 with my Brick, on Fri nite @ Cedar Falls (IA) Raceway, alt 850', when the temp was 86 deg and extremely humid. Did a 13.220 when it was 91. My tops speeds were between 104 & 105.95 moh! Speeds were the best I've ever seen.

 

[EcoPowerParts]

Bob what kind of boost were you seeing on that run?

 

[EcoBrick Bob]

There are over 600 logging points in a Live Link 1/4 mi log. This means 5-6 points for every MPH.

The boost varies all over the place, but tends to be highest at higher rpms. My max boost was a TIP of 72. To get the actual boost number you divide by 2 & subtract 15 (actually 14.7) So my maximum boost was 21 + PSI. I guess I could look at the log and list the TIP at each 5 mph increment. Will attempt to do sometime tomorrow. Log isn't on this new laptop.
