Maybe you guys can go explain to the tafe teachers your theory.
Done my trade and have been a tradesman for 10 years now.
This theory is valid on N/A
Ask your self this question why are golf balls not all smoothed they have all little holes all over them.
A golf ball that will be smooth all over wont travel as far a as the turbulent ball.
Thats all i have to say.
Hmmm... i was going to ask myself that question, but then remembered I'm not retarded and I successfully finished high school.
My car doesn't play golf, nor an I intending on having it suck up gold balls.
FYI, yes, gold balls have dimples to cause turbulance around them and therefore fly further but unfortunately the same theory cannot be applied to intakes.
Completely different airflow principals apply.
I think I've said this in the past, just because you have been doing something doesn't mean you're good at it.
In the case of intakes, you want the pipes to be as smooth as possible to reduce turbulence.
Either way, it has absolutely nothing to do with air/fuel in the combustion chamber.
Turbulence is needed AFTER the fuel has been introduced and last I checked, fuel is not introduced into the intake pipe.
As wraith said, the reason the factory pipe is ribbed is because flexible, because it quietens the intake and one addition form me is that it prevents engine vibration causing stresses on intake components unnecessarily .
