All these numbers and big words... I can feel a headache coming on...

With regards to enlarged intake/pipe to throttle: There is a reason why the pipe narrows before entering the throttle: it increases air velocity to the throttle body. The best way to explain this is using the example of a garden hose. Run a garden hose without a nozzle. You will find that you have low water pressure until you turn the hose on to near full. Next, run the hose with a nozzle, at nearly full pressure. Put your hand against the water. Can you feel how much more water pressure was created by simply having the water's passage restricted before exiting the hose? This is how the pipe-to-throttle narrowing works in your Ford. Incorrect for a couple of reasons, the first being that air acts completely different is it is suck as opposed to blown, the second is the air is compressible, water is not. The last is that it is about mass flow of air and as you example shows the mass flow of water is the same you just by default have increased the pressure to compensate. The fluid dynamics of what will work and what won't are quite complex and probably aren't worth going into here. The easiest way to test all of this is the to measure the restriction on the inlet with a manometer and try difference setups until you get the least restriction. This will give you the best flow, on a side note I would stand rooted if all Ford had to do to get another 10rwkw out of their engine was fit a big pod filter. IT would kind of make tickford feel sily messing around with variable cam timing and such 
Cheers Paul

This would allow the air to move in an ordely fashion and not much congestion/restriction.....that COULD work.......but im only thinking in lamens terms. phong =P~

those stupid hyclone things have been tested and are absolute B/S, just the same as vaporate, magnets and fuel tablets.

but the concept sounds good =D ah wells i guess ill just stick with a stock one or get a mandrel bent intake =D. cheers

It does sound good, but in reality turbulant air does not move as fast nor is it as dense.
Not to mention the fact that the twists and such acutally create a restriction. |

I run my car with no intake piping.
Just have the throttle body open to the engine bay. I have no restrictions at all, not even an air filter. Street lights became lines as I jumped to hyperspace. Man what a rush. |

Exactly
Try taking a deep fast breath with your mount wide open. Now open your mouth just a little and try it again. No doubt the velocity is higher when your mouth is mostly closed, but does it help get air in your lungs?

Yeah i agree, yet they still seem to sell a s**t load. I saw them at the Motor Expo here in perth. Where the hell do they get this R&D from anyway? Anyone can pull figures out of there a**. |

its amazing what people will beleive when 'dyno figures' and a few select tesimonials are quoted.

(I wonder how far this analogy will go...) When you need to move lots of air fast - velocity comes second to flow.

the first thing you learn if your a runner is in thru the nose out thru the mouth?
