The power won't become peaky until people get into upgrading the turbo with something much larger than stock. The DI system should max out before a huge turbo is needed so if they are also upgrading the DI system, they would be WAY into mods before it became a peaky engine that makes all of its power over 4k (which of course would necessitate upgrading cams as well to increase the peak rpm range).

 

IMO, if it's like the ST, it's already peaky. Just all low/mid then falls off a cliff... I hated that feeling in a car with sporting intentions..

I gotta go pick up a 328 and see how the BMW version of the turbo 4 feels these days...

Occurs to me with DI that the fuel side bottleneck could come anywhere, the dynamics of the low pressure side of the pump could be pretty touchy, and upgrade parts are probably going to be a bit more interesting..

All that negativity out, I'll predict we still see a 10 sec Ecoboost S550 by the end of the year...

 

I guess one discussion is peak numbers, and undoubtedly you can whip an Egoboost 2.3 hard enough to get into the tens, but I'm not sure that's a mule I'd really want to ride. Sometimes a bigger steed, a little less stressed, makes for a more enjoyable ride.

 

I'd like to take a moment to summarize this thread:

1) Ford gave us 3 options in engines. You are free to choose your own based on your own impressions/knowledge/bias
2) If 0.4 second difference in 1/4 mile times matter to you, get the V8

Done

 

Thank you for your contribution to the discussion.

I'd like to add one more item to your summary:

3) People with nothing to add to a conversation will always find a way to increase their post count.

Here's another summary:
The Ecoboost platform in all it's guises, like IRS, is a technological advance still in its early stages in the Ford development cycle. Yes, it's the way of the future, like the modular engine program was in 1992, but this gem is far from its final polish.

It has certain advantages already, but it has been over promised and under delivered as far as many in the general enthusiast community online are concerned.

Alternatively expressed, anything not Ecoboost is old school crap and if you disagree you're an ignorant caveman..

Excuse me while I go get my popcorn.

 

Ah if only life were as simple as people on the internet like to make it sound. lol

 

Here's the thing that's getting lost in this discussion. Even a simple tune can allow Ford to void your power train warranty. I just built a NOT FULLY LOADED Ecoboost Premium Performance Package convertible on the Ford Canada build and price. That came out to $53,335 out the door including taxes. I can tell you one thing absolutely for sure...I am not spending $50K+ on a car and then letting Ford void my warranty by adding an aftermarket tune.

If the Ecoboost is all mid-range torque and falls flat on it's face at 5200 rpm in its stock form, it is not the right engine for me. These are not inexpensive cars. If anybody is willing to buy one and toss the warranty in favor of more power, have at it. This is not the path most buyers will follow. Maybe five years from now when the original owners are ditching their stock tune Ecoboost Mustangs, enthusiasts can pick them up cheap and start throwing money and parts at them to make them fast. They may become legendary with the tuner crowd and I am certain that performance shops are going to get some good numbers out of them very soon. However, the original owners are more likely to be stuck with the narrow 3200-5200 rpm torque band and weak high rpm performance from the factory.

 

the 4.6 was not a high revving engine... I think the redline was under 6,000..

FYI anything you do drive train wise will void or "harm" your warranty. The tune point was for people that wanted more power out of the motor be it V6 or EB2.0..


I think we have two kinds of mustang buyers.. Those who care about warranties and those who want more power. My last few mustangs had mods on them within literal hours of owning them. My current car had crazy mods on it within months.

 

It's not just caring about warranty. It's also about protecting a significant investment for most buyers, even if it's only an attempt to minimize potential losses at trade-in time. I know there are some people that don't care about warranty but I am unwilling to take a $6-10K hit to replace a popped engine because my warranty was denied because of a tune.

As for those who want more power, I humbly suggest that the 5.0L is the better option to start with than the Ecoboost. Why void your warranty to get a 350 hp Ecoboost when you can buy a 435 hp Mustang for $6k more (in my case, configured option for option vs. Ecoboost). If you want more power than the 5.0L, warranty be damned, go for it. It will be awesome.

 

Agreed, the whole CAI and a tune thing has never appealed to me to begin with. I tried a CAI on my 2010 Mustang, it did nothing for it. In fact below a certain temperature the tube would vibrate against the filter housing when I would cold start the engine. It was annoying as hell. But anyway, the whole tune thing on a stock engine is pointless as far as I'm concerned. I know a lot of guys swear by it but the testing has all come back the same. You don't really get that much of an improvement in performance and often its barely noticeable. But for that you have to lay down anywhere from $300 to $600 bucks and void your warranty while you're at it. I wouldn't waste my money but to each his own.

The reality is that if you really want to improve the performance of your Mustang its going to take more than adjusting a few parameters in your tune. You need to look at things like performance heads, forged internals, forced induction, cams, different rear gears etc etc. And of course when you do something like that you will have to have a tune to account for those changes. In that case it absolutely makes sense to have a tune. You must have a new tune in fact. But tuning a stock engine while not changing any physical components of the engine is just a waste of money to me. I wouldn't begrudge anyone that wants to do it and I think a lot of guys just do it because they really want to feel like they've done something to improve the performance of their Mustang but can't afford the many thousands of dollars it would take to really do that.

 

I am just going to be blunt here... You do not know what the **** you are talking about. A basic tune on a EB can be worth a second in the quarter mile..


most if not all CAI's really don't do much and do less on the V6 motor vs the V8 motor. Tunes are where the power is made.

 

Yes bluntness seems to be your thing. If it was that easy to get another second in the 1/4 mile than Ford would just put a tune on the car from the factory wouldn't they? Or could it be that they don't because what that tune is really doing is just leaning your mixture out? A lean car will always run faster but at the cost of shortening the lifespan of the engine. And frankly you don't have a clue what a basic tune on the Mustang EB will do since no one has done it yet. This isn't a front wheel drive Focus we are talking about.

You take the following video for example. Stock numbers were 270 hp with 260 lb ft torque. With an 89 tune he got a smashing 6 more hp but the torque dropped to 249. With the oh so impressive 93 tune he got 7 more hp but still had lower torque at 251. I am utterly unimpressed. Oh but let me guess, the magic turbo will cure all of that right? The same turbo that right now has numbers falling off the cliff at about 5K rpm.




By the way, the factory ecoboost Mustang runs the 1/4 mile in 14.1 while the GT runs it in 12.8. So you're telling us that with just a simple tune the ecoboost will be pretty close to Mustang GT performance levels? I'd like to see that.

 

fyi all good tuners run a rich tune.. Ford detunes motors like all makers to lower wear and lower warranty costs.

 

How about a ford racing tune??





its not on a ford focus but I think it will do. Its the ford racing 550hp whipple kit.

or

How about the ford racing tunes for the mustang or focus and so on.


FYI People in the cute little 2.0 focus ST have been saving a second or so in the QT mile with a tune and little else. So if the poor crap box focus can do it im sure the mustang can do it. Have you even seen into the EB flex?

 

I said good tuner.. you posted a bama tune. also you are still missing the point that a boosted motor is different from a N/A motor.

 

who said anything about the GT? We are talking about the value of a good tune. No one has claimed the GT output from a EB2.3.

 

If it weren't for Trackey on the Boss, I would not get a tune until my warranty was expired. Even the Trackey reduces your warranty if your engine pops while the red key is being used. If I am not mistaken, Ford Racing provides it's own warranty on it's tunes but it is not the same as the factory comprehensive warranty.

It's not like a Ford warranty is good for anything anyway. I haven't updated my other post yet but I haven't had a Ford vehicle successfully repaired under warranty in 13 years. Two out of the prior three Fords I owned were traded in with issues that I could not get repaired under warranty. Currently, both of my 2013 Fords have issues that I cannot get repaired under warranty. So forgive me for saying that, if I'm not getting a GT, I'd rather have the V6 than the Ecoboost because it's simpler, reliable and less likely to need warranty service that's proven entirely useless in my experience. But I'm not getting a V6 without the Premium Package, so here we are....

 

The EB motor is not a complex motor. All engines have a unique character and strengths and faults. We have had turbo motors on cars for a long long time and its simply not going to be changing anything soon. The V6 is going away.. why would they keep it when you can get a more carbon foot print friendly motor that gets the same mpg's and lightens the car.

thank you for bringing up the track key! Proof a tune on a stock car can make a difference.

 

I'm not missing anything flag. Good luck with your ecoboost Mustang. I hope you change the world lol.


PS I saw a Ford Flex with absolutely no idea what the owner had actually done to the car to make it faster. It must have been the magic tune! lol

 

met a tuning team here in phx 2 years ago with a awd flex and a intake and tune that ran 12.8 all night long at Friday night drags.

im not getting a EB mustang. My next mustang will be a Shelby vert in another year. I always buy the v8 mustang.
