I wonder if acetone smoothing would help at all after porting.

Probably the worst test ive ever witnessed. Proved absolutely nothing. A manual car on the street?

Porting the plastic surely roughens it and making it worthless, I would only take a brand newly smooth designed port to begin with! Just my opinion!

i never understood the idea of supposedly making a modern high-performance intake manifold "better" by making it rougher. i think it's a bit of a scam, like throttle body spacers and billet oil pump gears. if it was so easy for manufacturers to get some extra power, why don't they?

There is no magic in the smoothness of the surface in an intake manifold folks. lol. These comments are funny. Now that said, after a few hundred miles the surface will be smooth anyways from the gases/vapors etc - so that should tickle your fancy. LOL

No surprise here that there wasn't huge gains. With that said, anyone who has gone "fast" Naturally Aspirated can say "it all adds up" and "it is not cheap" - I am sure these port jobs will pay off once these cars are making more power.

I’ve seen port work on aluminum where they dimple the floor like a golf ball and it leads to higher “laminar flow”

You want to create a thin layer of turbulence for the air to flow on top of the way I understand it.

too smooth/polished is slower.

I think this is the stupidest and riskiest modification. If air flow is your obsession you should remove the carbon traps or change the cold air intakes. if that's not enough... install a supercharger or turbo.

It’s physics. ICE engines are air pumps with fuel as the catalyst to keep the process going. More air=more power. The hats also why we love forced induction. However, the modular engines have long needed tuning and in some cases, cams to make use of the extra available air in naturally aspirated setups. You’ll see some fans with a ported Intake, but minuscule —— until you also open up the exhaust and tune the thing.
The issue here is Ford locking down the tuning so the car won’t respond to mods like it used to.

I am confused a bit in regard to the porting. Why not port the throttle bodies first? Isn't that a better place to start porting? I asked the guy in the video and he said someone else is doing that...?
