if you were to make a rifled round port, you know spiraled on the inside like a rifle barrel... wouldn't it do higher numbers than a smoothbore port.....think of accuracy with a shotgun compared to a rifle....i mean wouldn't that do wonders for outlaw potentially? any comments on this???

You can't compare bullets with air. Spirals on the inside of the port would do nothing.

I dont think it would be possible to make air spin with nothing but some spiral grooves in the port. And IMO the air velocity wouldnt be fast enough to benefit from a "rifled' port even if it worked that way.

My understanding is that the reason a rifled barrel improves accuracy is because if the projectile is rotating, it has less tendancy to flip in air. Flipping hurts accuracy. I don't think a rifled port would help anything, but if you wanna try I know where you can buy rifled PVC. Not sure how big of a diameter it comes in though and it's pretty expensive.

i think there us merit to his idea... and i must admit that i've actually thought the same thing myself..... and really i think its possible, you're trying to reduce turbulence, and creating a spiral like movement should do just that..... back in the day (BOUT 3-5YRS AGO) people were actually talking about the same idea but with computers & fans.... using a spiral like guide with a fans helped decrease noise and turbulence.
however i don't think rifling groves would do anything... but rather you'd need some fins... unforunetly... if you made the fins too big, they might actually make things worse due to increased surface area, thus issues with laminate air.
i think the gains would be more with port noise reduction than with spl.

Another thing to consider is that, your subs are gonna move air back And forth- not just in one direction. I had thought about how you have those spacers which go in between the throttle body and the intake. They too are have a spiral that helps preformance.

dont forget you scope!!! ( you can then aim your db's)

This is why it won't work. The air moves back and forth extremely fast in a port, therefore if a vortex could be set up with spirals in the port, the direction of spinning air would also have to change direction very fast.
Spiraling air may help with flow in some cases, where the airflow has a relatively constant speed in one direction, but it won't help when the air goes back and forth such as in a port.

talnlanky and the guy who said the thing about the spacer get what i'm saying, it wasn't a serious thing i use big slot ports...it was more of a question for my friend i know that the air moves in and out very fast in a port but....put your hand in front of it.......it blows it does suck back but it feels like it blows so we were thinking mabey rifled ports and aiming right at the mic....lol like the guy said about the scope.....

I would think it would create more of an obstruction to air flow. We round the corners or ends of our ports to guard against this kind of thing. In the examples of both the rifle and the intake plate, the bullet and the air/fuel mixture are moving only in one direction and they are rotated for different reasons. If anything, shouldn't we smooth and wax our ports for more effecient flow of air?
