[?] '18 Intake Manifold on '15-'17

[HISSMAN]

I would hold off just in case, though I highly doubt it, the Bullitt has a slightly different manifold. It would be sick for it to have a twin TB like the '01 Bullitt had over the regular GT.

problem with that will be the cost of that IM. Right now if you can get the 18 IM and make the same or more power as a 350 IM it is no brainer pricewise, but the bullitt if it did come with a different IM will most likely come with a heftier price tag too and therefor not be such a no brainer cost wise

I can't argue with that, but what if it has Cobra Jet potential? I guess it depends on what the end goal is, like with any mod.

What is the part number? Did I miss it? Is there any fitment issues with the 15-17s?

Here is the graph from that post

What intake/filter was used on each run? What tune? (OEM 2016 GT tune?)

Aftermarket tune, but no tune change between runs (was tuned for 350 manifold). Doesn't say what CAI.

 

[FIREBALL_BRIAN]

stack this with the ford performance pack 2 using the GT350 intake and tune.

Anyone else having a hard time figuring out which line belongs to which manifold when they start intersecting/crossing over?

Took the plunge. For $275 shipped, what the hell. Not worried about recouping costs if it doesn't work out lol.

I think the higher line (for both hp and tq) is the 2018 GT, which then drops below the other lines at around 72-7300. So the GT350 loses a little bit of torque and power under 7200rpm and then gains over that.

Sounds about right when compared to the 2017 GT manifold, where the GT350 lost power until around 7000 and then gained from there. Except this time, the 18 manifold holds a lead until a bit higher than that.

I read the "top" line was the 18, but what about the HP crossover at 3200? and then at 5100? I assume that the 18 is the one that falls off at 7200 as well.

Tq crossover occurs at the same rpms as HP.

Maybe it's just my monitor, my eyes, both? but I can't tell which line goes where with the first 2 crossovers.

Mind sharing who you ordered from? That is a smokin' deal.

We did some manifold testing ourselves recently.

All pulls were done with the same tune to gauge what difference each manifold makes. All runs had the IMRC valves open and disabled.

Stock 2015 GT vs GT350 vs Stock 2018 GT vs Stock 2018 F150

F150 blows them all away until about 5000 rpm. The GT350 was best up top from 6200 rpm and up. The Stock 2015 manifold is a good all around manifold up to about 6500 rpm. The Stock 2018 is the Goldilocks manifold. Not quite as good on torque as the Stock 2015 manifold and not quite as good as the GT350 manifold on the top end, but sits right in the middle of the two.

If 2018 owners are okay with giving up some low end, decent top end gains should be achievable with the right manifold, and with the 10R80, that would be a good match ;)

 

[sstone]

Very interesting, thank you for the info! Curious what the low end would have looked like on the 18 manifold with the IMRCs enabled when compared to the 15 manifold with IMRCs enabled. Makes me think that running the imrc's on the 18 will get you much closer to the F150 numbers below 3000.
Why anyone would want to be turning that few rpms............
