S650 Ported Manifold?! - 2024 Ford Mustang GT 1320 Junkie Ported Manifold Comparison 

That was the problem for the C8 corvette for about the 2 years and someone finally cracked the code. I just think it will be a matter of time.

No doubt...gheez

Even if you could make it fit tuning would be the biggest issue as the PCM on the S650 is designed to manage both throttle bodies individually from one another. The F150 and S550 mustang PCM isn’t capable of that. Not saying it can’t be done but it would take a lot to make it work until someone comes out with a solution on how to manage the twin throttle bodies.

I thought the HP guys , have been playing with speed density for years? I tried reading a few posts but they were talking way above my understanding!

Smoothness, contrary to what you might think, isn't as good for airflow, hence why you don't see a whole lot of "ported and polished" versions anymore. The ported 18+ Mustang and something like the ported LS3 intake are both plastic and so good that the aftermarket has had trouble beating them.

You want smooth on the TB side and rough where fuel is introduced. We’ve tried dimpling. In heads and intakes. When done right it does have a certain effect that helps flow and atomization but the effort vs reward isn’t as high as just a nice port job with proper port shape and volume. But smoothing the intake where only air runs over it is ideal. We get the best flow numbers. But plastic intakes don’t really gain enough from what I’ve seen to really be worth the extra money or hassle. It’s one thing to clean us the flashing from the molding process. But the gains are generally minimal. But with the mustang stuff I really don’t know.
