15-17 vs 18+ engines

[w3rkn]

I think it would be an interesting comparison - I'd wager that the stock turbo is small enough that most folks wouldn't notice any additional lag during normal use, but the folks who cared to add a more efficient header type exhaust would really benefit. My previous Honda Fit also had the integrated manifold going on, but it wasn't done for performance purposes. Moot point given that Ford isn't going to change the design any time soon.

I don't think you understand...

BMW and other are trying to do what ford did, in moving the turbo as close to the exhaust valves as possible. I am really clueless why you keep talking about headers and Ford needing to change their EB design... when Ford keeps winning Engine design awards.... because of their Ecoboost design.


And yes the 2.3 EB VE can be increased by port work... almost like any engine. I don't see your point.

I wish Ford would ditch the integrated exhaust manifold. I'm sure they have fiscally-valid reasons for doing it that way (emissions, fewer parts, etc), but I'm sure the cruddy ports cost the engine an easy 20hp. I would wager it's also the cause of the mushy exhaust note this car has.

They also make the engine sound like total shit. When they use a head like this, 99 percent of the time the engine has a very bad rasp to it. Look at the fiesta st vs the focus st
The 1.6 uses the traditional manifold and turbo not only making turbo swaps really cheap but they sound fantastic

It's all trade-offs. You might get better exhaust flow with a header, which might produce more horsepower, but moving the turbo farther away from the head will reduce response time. More horsepower is great when you keep the engine up around redline, but turbo lag reduces power down low, where a street car engine spends most of its life. That would make the car less driveable.

The main reason why they do this is for emissions and response time. They use the engine coolant to help cool the turbo as well as warm it up. That’s a big issue with these DI turbo engines is that on cold starts DI isn’t as efficient as port injection for getting the combustion chamber up to temp, this is also why you get a lot of threads about cold start surging, misfires, odd little issues, remember DI has a cooling effect in the combustion chamber this is great everywhere else but startup lmfao , this also means it takes longer to get the cat up to temp. It’s all a domino effect, so by putting turbo right on the head, they solve a lot of little issues very quickly. The downside is it’s a serious pain for the aftermarket for upgrades and IMO intergraded turbo fold engines sound like ass most of the time. Rasp city

Tradeoffs... My advice is keep the factory exhaust on it and enjoy the fake soundtrack on the inside. That way you don't annoy the neighbors while you live in Ford's audio fantasyland. I can live with that tradeoff given all the other benefits of the design.

If ya want my personal opinion the MK7 and 8 fiesta have the best sounding small engine exhaust. The MK7s sound amazing even with a straight pipe the same can’t be said about the 2.3 lol the focus RS sounds good but holy crap does the everyday Eco with a muffler delete sound terrible

 

[TorqueMan]

You know, on my 18, I can NOT hear any fake engine noise. In fact, neither can any friends who have been in the car with me. Before my muffler delete the car was nearly silent.

Hmmm. I heard Ford ditched the sound tube on the 2018 Bullitt Mustang, but I haven't heard anything regarding the Engine Sound Enhancement on the 2018+ EcoBoosts. Anyone with Forscan willing to take a peek and see if it's still there?

I have a 17 and disabled it via forescan, imho I think it sounds better disabled, and better sounding music

I disabled ESE on my '17 as well, but ended up turning it back on. Why? Because I couldn't find a way to disable ESE without also disabling active noise control, which in my opinion really cuts down on road/wind noise. That's more important for me, because I use the car for a 70-mile round trip commute on the interstate.

I had to disable anc due to JL Stealthbox, I don’t notice outside noise though. I listen to music too

Its a hum, does your exhaust sound ONLY behind you? cause that was the biggest difference when I disabled it, the sound wasn't around me, but behind me now.

 

[TorqueMan]

It may be there, but I can't hear it.

It's subtle and well integrated with the car's sound system. I really noticed it the most when I turned it off. Even at high RPM the stock exhaust is almost dead silent. You get the strange phenomenon of a really quiet car at low speed, even when at really high RPM. Once you get rolling, however, the road and wind noise really pick up, and cabin noise gets intrusive, especially on poor-quality pavement.

Probably the only way to know if ESE is on (without checking with Forscan) is to pay attention to the engine noise. If it gets louder under acceleration as RPM ramps up then you are probably hearing ESE.

So it's a weird trade off: With ESE/ANC off you almost can't hear the engine at all, but you get a lot of road noise. With the system on you get FAKE engine noise, but muted road noise.
