18 F150 manifold???

[BmacIL]

So what would be best on my procharged setup

@ahl395 has had the F150 and 18 GT on his centi blower car. Stuck with the 18 GT manifold. I'll let him share his thoughts.

I did have the 15-17 F150 manifold, not the 18 though, so I'm not sure what improvements have been made.

I've talked to yote about it before but my thoughts are that I preferred the 18 GT manifold. The F150 hit crazy hard in the midrange. I would even say substantially better, especially around 4-5k . Although after 6k you could feel that it did not really want to rev higher. The drop off became extremely apparent when I switched to the 18 GT manifold, which absolutely takes off after 6k. The trade off in the midrange is worth the insanity over 6k, even if I cant rev that high often in daily driving.

Yup, because that is what matters. When you actually need to go fast, the higher rpm power makes the difference. Even the stock 15-17 GT manifold is a good all arounder and will be faster than an F150 manifold car. But imo the Gen2 motor has a willingness to rev and I think stock 15-17 GT manifold doesn't take enough advantage of this. That's why to me its 18 GT manifold FTW. Of course the CJ is the ultimate king, but requires hood mods or lowering the engine to make it fit.

For a stock ish manifold to me it goes in this order:

1. 18 GT manifold
2. GT350 manifold (close 2nd, could be 1a. and 1b.)
3. 15-17 GT manifold

I dont like the F150 manifold on the Mustang, but I do understand it. The low end torque could make it easier to have some fun on the street, as long as you don't care about revving it. But then I still say you didnt exactly buy the right car for that. It just doesn't fit how the engine and cams are configured. The 18GT is the goldilocks, right in between the 350 and stock GT manifolds. Power to shift at 7500 and minimal torque loss, less than the 350.

I know there's no F-150 mani

But Alex did a pretty interesting comparison between, stock, 18, and GT350

Anyone know if the 18 f150 intake manifold would work on a 11-14 gt. I know the 18 gt intake manifold works I would assume the f150 intake manifold would be installed the same way

 

[Mustang_Lou]

I haven't heard of anyone trying it yet.

I would be curious to see if anyone does end up testing this.

Seeing how the Gen 3 coyote is made to spin out more, but the F150 is more intended towards towing, I wonder if they made an intake that flows well up top but also gains low end torque.

It would work the exact same. You would need lockouts like with the 18 GT intake.

Should work fine since many people have installed 18 GT manifolds on their 11-14 GTs. Since you dont have IMRCs just lock them out and tape up the connectors.
