difference in 2017 to 2018 mustang

[Coyotes55086]

So I'm just trying to understand something here . The main differences here between the 2017 and 2018 mustang. Do most of these differences come from the intake manifold of the 2018 ? if I changed my 2017 manifold to a 2018 manifold , what exactly would this achieve?

No, there are major internal changes to the engine. That’s why it’s called Gen 3.

A bad running car.
If you want the same or even slightly better performance than a Gen3, you can use a ford racing power pack 2

Uhh..

What?

What?

Is that a question?
Adding a gen3 intake manifold without tuning the car for it will make it run like crap
M-9603-M8A. Look it up and dyno numbers

It seems from his post that OP thinks the major change in the Gen 3 is the manifold. We know it’s a lot more than that.

But you’re right, just changing the manifold is pointless.

Gotcha. I thought you were responding to what the difference is..IE a bad running vehicle.

But you meant the intake without a tune part. I misunderstood bc he didnt mention not getting a tune.

From what I can tell, the main advantage of the Gen 3 is that because of the dual sets of injectors, you can run e85 with only a tune. It has never been clear to me if a gen 2 needs more than a tune to do the same.

Gen3 has obviously more power stock and more potential due to higher CR (enabled by DI), better flowing heads, bigger valves, more aggressive cam, 5 extra cubic inches...

if OP wants something like the stock gen3 power-wise get FPPP2 or 3 or a bunch of bolt-ons including an 18 or GT350 IM AND a tune. Even with NA mods won’t be able to keep up with a gen3 on E85 and headers though, esp if it’s bolted to an A10. If you go FI your gen2 shines on pump gas...both great FI on E85.

I think anyone going E85 on any Coyote is encouraged to get a fuel system upgrade, but I’m not sure about that.

You don't need bigger injectors on a gen 2 for e85. I use e85 with only a tune on mine.

If you go to a 2018+ intake manifold you need 47lb injectors for e85

I looked into this somewhat. There was a really good youtube video from vmp where he tested out every intake manifold. 2018 and up intake manifold will let you keep power up to 7500 rpm but the 15-17 will drop off at 6500. Looking at his dyno the 15-17 had more power down in the mid range.

Here is the video

I think there are other driveline changes too, like the driveshaft and probably flanges...

There was also some suspension changes. As the non PP cars got some components from the PP cars as well as standard.

Everything you need to know about the differences in the 5.0 Coyotes is here - it’s been used by many on this site:

There are numerous differences between a Gen 2 Coyote and Gen 3 Coyote, some small, some significant. Here's a complete list from Ford:

The physical component dimension changes are incremental - Cams have 1 mm more lift (intake and exhaust), bore is increased by 0.8 mm (overall 307 ci vs 302 ci), valve diameters are increased by less than 1/2 mm. The compression ratio is increased from 11:1 to 12:1, a pretty big change IMO. The head bolts are 1 mm longer.
