Ecoboost blown engine

[neodark]

Well let's see, my bolt on GT ran low 11's. Does your 4-banger do that?:shrug:

Exactly

haha, yes :lol:

I wouldnt take what these GT guys say to heart, they are a little touchy about our I-4. Considering some of them get beat by a modified Eco unless they are willing to add force induction.

LOL!! My friends 2014 5.0 run about mid 11's with tune and bolt-ons with no stress on the engine!

You may want to retract that statement.

To the OP, sorry about the issues.. I read that Unleash's tune isn't that aggressive and so I'm willing to bet, that perhaps a defective part may have caused the issue.

You know there might be something to the cold weather thing. Though I wonder if it is more related to the quality of gas in the winter. My engine blew last February I was on a 93 tune and wonder if the gas was up to snuff or not. Seemed to be a bunch of blown engines last Jan-Mar then they seemed to really die down over the summer.

Did he have a catch can? I read that blow by increases once it gets colder.

awfully sensitive this morning. I do find it interesting that yall GT fellas find your way into the eco section but only comment on blown ecoboost threads with comments involving insult to injury, but never seem to comment on threads like UPR Steve wiggling his way into the 9's. curious how that works

Well isn't this the sad truth. Brings a whole new meaning to "Kick em while they are down."

Agreed - and I had a pretty decent tune on my last car (Taurus SHO, Livernois 93octane tune) and would NOT have expected Ford to replace the motor if it grenaded. Tunes are GREAT but you have to understand the risk and not whine when the manufacturer denies a claim.

How many miles did you have on that car with the LMS 93 and did you have any cold weather issues? Obviously you didn't blow the engine, but even LMS has had periodic minor issues with a few of their SHO tunes in the past when they first got into EB's.

They're right, though. Sorry.

This ^^^. There's pros and cons to both, even the V6 has its advantages. Simply put a FI V6 will make more power on pump gas than a FI I4. A FI V8 will make more power on pump gas than a FI V6 or FI I4....

What it comes down to is COST. The Ecobost stangs represnt the best bang for buck to a point. For just $1300 you can run a good quality tune, FMIC and 160F thermostat on an otherwise stock car and compete with stock NA V8's that cost 7k more just to get into and get markedly lower fuel mileage coupled with poorer handling (due to weight).

The down side is the max potential is lower and reliability will suffer at power levels modified V8's can make without breaking a sweat, lets face it, with the 5.0 you have 2x the cylinders and more than double the total displacement. Cost goes up exponentially at some point and from a cost vs. performance perspective the V8 at some point will have a better cost vs. performance ratio as the I4 nears the limitations of its displacement capabilities. Case in point, the guiness book of records had a 1200 HP honda civic, the engine block was Titanium and cost $100,000 to have custom machined...it was in an actual FWD civic and all that power was useless, but it was possible...

There is NO replacement for Displacement (Just look at GM's 6 liter in the 2016 Camaro, runs a 12.3 stock...sure a tuned NA V8 can do that, but not stock, but the GM power plant has 20% more displacement).

In the street car, autocross and circuit track category a lightly modified EB does exceptionally well at its price point for very little put into it cost wise, but again there are risks and a blown engine is one of them if care is not taken to choose a tune with proper engine management schemes and address the additional cooling needed to ensure longer term reliability. The more power you push, the more likely a catastrophic failure. The trick is to balance power with reliability, at some point you will have completely eaten away the safety margin and small changes in environment / fuel quality / driving habits may push things beyond their limits.

The whole reason I focused on cooling upgrades first was reliability. I upgraded to a 2" mishomoto radiator, 160F thermostat and large FMIC to aid the LMS 93 tune in making safe power. Even despite all that there is some risk assumed even if law prohibits the Mfg. from blaming the modifications without proving them to be the cause of the failure. Testing is important, but if the test doesn't account for ALL possible conditions, once you reach a condition outside of the test, you can run into problems. Unless you have an environmentally controlled engine dyno chamber, the next best thing is to tune with a margin of safety and then test that car out in real world cold weather conditions and monitor the key parameters with an actual data logger system (one that logs data directly from sensors just as the ECU receives them, remember OBDII reports at only 200~300ms intervals, the PCM refreshes ever 8ms or 50x that speed, lot can happen in that time, events can easily be missed due to aliasing).

Lesson here is, if you get a shop tune, make sure you get it tuned during winter or re-tune during winter to make safe power. The other option is to find an OE like tune like Ford Performance or LMS which also have already tested to cold weather operation (but you will not make quite as much power as a shop tune due to the added safety margin to account for environment and individual car differences).

Excellent points man, you nailed it. Yes I always wanted the V8 and that's because I'm fine with the power in stock form. Once I get the car, I can't tune it or do anything crazy since I have no cash cover repairs on my dime.

Bang for you buck, the EB Mustang wins.. Like the above mentioned, with $1300 it can pretty much get to a stock GT level and might even feel quicker from stoplight to stoplight.

If one wants to remain stock or do mods that doesn't mess with the warranty, then yes.. There's no replacement for displacement.

Exactly

Notice the previous person said "some of them" certainly not all GTs, but there are numerous ecoboosts running low 11's.

You just further proved his point regarding GT owners, cool your car ran low 11's, but mine costed less. Both engines have their pros and cons. Both engines are fantastic platforms, not sure why we cant just all get along? :shrug:

 

[tw557]

And as much as I wanted a GT myself too, my research did point out they are not bullet proof and used coyote motors are very expensive. BBQ tick, cylinder 8 and oil pump gears. All current high performance motors have become very sophisticated and complex with plenty that can go wrong no matter how many cylinders. Although a rod thru the block is probably less likely in the GT.

Well Dirty-EB-Chicago was the 1st to bring up the Ecoboost beating a GT. Not me. All I did was comment on the warranty aspect.

Me too, I've always loved the V8 sound and pull, there's just nothing like it. In fact I'll bet every EB owner on here would trade their EB, even modified for a GT350 of given the opportunity.

That mustang variant is just awesome in every way (except fuel economy). It makes great power, has legs that go all the way up (8200 RPM, let that sink in), extremely low un-sprung mass (carbon fiber wheels), magnetic suspension (I believe it's active) and looks that almost kill...but its $66,000 lol.

But since that scenario is 99.999999999999999999% likely to NOT happen, I am thankful for options like the ecoboost I4. A full bolt on EB on pump gas can run mid 12's, which is the same as a stock GT350, not bad for car that's less than 1/2 the cost!

And just a little helpful hint. "Costed" is not a word.;)

Asking someone if his "4-banger" is a low 11's car has NOTHING to do with commenting on the warranty aspect.

I didnt realize this was english class where proper grammar was expected :lol:

Notice how you didnt dispute the point I raised though. Nor did you comment on any of the previous posts including ones about the ecoboost that is now in the 9's, you just chose to comment on the one with a minor grammatical error that didnt change the meaning of the post at all.
