Official 2.3L Ecoboost Thread

[Johnnybear]

SO they are starting production of the car but yet they have not come out with final numbers for the car? How can that be? I am very curious to find out about the HP on the EB. I think if I am going to get a new mustang and not a used one, it will be more of an every day car so the fuel economy will be a factor-but I would rather have 330 plus HP than real high MPG.

I think 330 will be my line. I would be disappointed in the extra money paid for the EB if there is less than 330 horse power.

330 horsepower shouldn't be a problem, regardless of the official number. Several sources, including this one: http://www.tflcar.com/2014/07/2015-mustang-ecoboost-350/ have stated that a simple tune will bring it up to as much as 350 or more. My mustang guru friend makes a living tuning mustangs and says he will take care of my upgrade the week I get my car. :bolt:

Not all that long ago, the average auto enthusiast didn't even know the power level of the average performance car... today, we expect a parade of information... It's kinda funny!

You'll void the warranty also just FYI.

This is a long and drawn out argument but I'll just remind you that even Ford reps have confirmed no single modification voids the warranty. The manufacturer warranty covers so much that short of driving into a river nothing will actually void it. In short, only a failure directly caused by a modification will not be covered. Everything else remains covered. I won't argue back and forth over this.

Thank you for the note on the warranty, I hadn't thought about that, but it is good news that the warranty will not be voided. Tony, the tuner, said he could always put it back to factory specs if I have to bring the car in for service. Unless there is a way for Ford to track changes that have been restored, I don't know how forward would even know. It is probably not something they would check for when I bringing the car in for an oil change. :shrug:

370 HP for a 4 banger is big power. Don't pay attention to all the magazines with the 600 HP EVO, that engine can't be driven on the street. Turbos and that is all of them have a surge line, this is where air oscillates in and out of the compressor, the air is superheated and will melt the impeller into a tootsie roll, perfect for eating, but not for engine longevity and boost. I have driven a streetable B18C with large turbo putting out anywhere from 350 to 400 WHP, with not 100% absolute care I could toast the turbo and / or engine in a matter of seconds. The engine could NEVER and should NEVER see any boost unless it is at WOT and at high RPM. Once again all turbos have a surge line and the bigger the turbo the more flow and boost it needs to see to keep the blade from roasting off. :shocked: If the GF drove the car the turbo would be toast before she got to the nail shop.

Hence there are NO OEM turbo application with large turbo and small engine as Joe Average would just toast the compressor by boosting the engine at low RPM, high gear loads. There is a " ported shroud" technology that gets around low flow low boost surge.

Here is a handy 400 WHP or 460 engine HP turbo calculator:
http://www.turbobygarrett.com/turbobygarrett/turbocharger

You get a GT4202 (too big I know but that is Garrett's calculator) which is about twice as big as the Turbo on the EB.
Heck you can just get to 1 bar of boost and 300 HP on the initial surge line. So basically it could only be driven at near max RPM and at WOT or the turbo would melt... just like I said.

The popular GT2876R (bigger than the disco potato) is already down hill at 460 HP, and that can't see boost under 100 HP and 1 bar under 200 HP. How high up in the rev range is that for a 2.3 liter?? Dunno but high.

Disco P to almost 350 HP (310 HP for best boost islands) : http://ep.yimg.com/ca/I/ntnsracing_2266_296331760

I can research the OEM 2.3 EB turbo but I highly doubt it is even as good as the Disco P, in terms of flow.

So no, despite what magazines say you ain't seen a "street driven" 460 HP anything at 2.0 to 2.3 liters. At least by mere mortals. Light car like a hollowed out Civic, no A/C or anything else that might lug the engine, crazy driver, super steep gears like 4.64, and a wad of cash... maybe. So clearly 600 HP EVO are like Unicorns and Rainbows. You see them or dream of them but can't touch one or ride one.

I know this is an old post... The longevity of a high HP 2L motor strongly depends on the design of the motor, the build components, turbo choice, and tune. A 600 hp streetable Evo is totally doable. I know this because I daily drive my 540 whp (600 bhp) Evo. It idles perfect, drives better than stock off boost, and provides ear-to-ear smiles when getting into boost. And my buddy has a 630 whp (700 bhp) 2.4L Evo that also drives great. However, there are limits as to how long they can be pushed without melting something. I can leave it in kill mode on the street and in the 1/4 mile, but if I were to take it out on a circuit course, I would definitely turn down the boost.

Anyhow, the point is that if the 2.3L motor is as stout or stouter than the 4G63, then 500+ whp 2.3L Ecoboost builds should be totally doable. Heck, one of my buddies just bought a Fiesta ST, and with just a tune and running E40, he's making 265 ft-lbs and 200 whp (figure 300 ft-lbs and 240 hp at the crank). I could see going up to 550 whp with the 2.3L motor, but for anything more, I think I'd give the V8 more serious consideration since its not hard to turbocharge (or supercharge) anything these days.

This is with the popular GT2867R turbo over-laid with RPM flow lines for 2.0 and 2.5 liters, even this small sub 400 WHP turbo is far into the surge range 1000 and 2000 RPM, even 2500 it is iffy, this is a small turbo. Probably, just a guess the most popular turbo of choice for the EB Mustang.

On the downshift, just my point, you can NEVER drive the boost, the car must constantly be downshifted. Sorry most people don't downshift from high gear whenever any bid of power is needed, hence the got a turbo car to begin with, to drive the torque over a wide band. Not a problem for me, as pointed out, I've driven big turbos on the street, it will be an issue for 6G Mustang as it really needs the turbo to move around 3400 lbs car. Trading drivable torque for 6000 + RPM HP bragging rights is just not where it is at on a car, a daily driven car.

Um a 2700 lbs SRT4, ain't a 3400 lbs Mustang and I would dare say that the average SRT4 owner is not a 2.3 EB owner. Still it would be nice to see a dyno pull of 400 WHP and what turbo you are running.


found a hub dyno (about 10% driveloss) on a 2.5 liter with the popular turbo chargers:
http://blog.perrinperformance.com/w.../10/dyno_turbo_08wrx3071rtuned16.7psivs18.jpg

Yep things don't start to sing till 3800 RPM, then of course things go crazy for 400 WHP..

This looks like it might be informative, but I don't understand it. Could someone explain it to me?
